Description
Herdbare blandinger av epoksydforbindelser og BF3. Curable mixtures of epoxy compounds and BF3.
Det er kjent at man kan omsette 1,2-oksydoforbindelser slik som etylenok-syd, epiklorhydrin eller l,3-[2',3'- oksydo-propyl]-oksybenzol med tetrahydrofuran i nærvær av Friedel-Craft-katalysatorer eller BFa. It is known that one can react 1,2-oxido compounds such as ethylene oxide, epichlorohydrin or 1,3-[2',3'-oxido-propyl]-oxybenzene with tetrahydrofuran in the presence of Friedel-Craft catalysts or BFa.
Da tetrahydrofuranet polymeriserer med seg selv i nærvær av Friedel-Craft-katalysatorer eller bortrifluorid, er det ifølge den kjente fremgangsmåte ikke mulig å oppnå homogene herdede produk-ter. Dessuten forløper omsetningen av epoksyder med tetrahydrofuran så vold-somt, at det opptrer lokale sterke overopphetninger og forkulling av den herdede harpiks ved større porsjoner. As the tetrahydrofuran polymerises with itself in the presence of Friedel-Craft catalysts or boron trifluoride, according to the known method it is not possible to obtain homogeneous cured products. Moreover, the reaction of epoxides with tetrahydrofuran proceeds so violently that local strong overheating and charring of the hardened resin occur in larger portions.
Det ble nu overraskende funnet at tetrahydrofuran ikke polymeriserer med It was now surprisingly found that tetrahydrofuran does not polymerize with
seg selv i nærvær av BFs når det dessuten er tilstede små mengder vann eller kvelstoffbaser. Derimot hindrer nærvær av disse forbindelser ikke omsetning med epoksydgruppeholdige forbindelser, men itself in the presence of BFs when small amounts of water or nitrogenous bases are also present. In contrast, the presence of these compounds does not prevent reaction with compounds containing epoxide groups, but
reaksjonshastigheten blir derved bare for-sinket. Dette har igjen den fordel, at uøn-skede overopphetninger og dermed forbund-ne uheldige innvirkning på omsetnings-produktenes egenskaper lettere kan unn-gås. the reaction rate is thereby only slowed down. This again has the advantage that unwanted overheating and the associated adverse impact on the properties of the sales products can be more easily avoided.
Gjenstanden for foreliggende oppfinnelse er herdbare blandinger av epoksydforbindelser, som beregnet på den gjennomsnittlige molekylarvekt inneholder n epoksydgrupper, idet n er et helt tall eller en brøk som er større enn 1, tetrahydrofuran og BF» idet blandingene er karakterisert ved, at de inneholder stabile komplekser av vann og/eller kvelstoffbaser med BFs. The object of the present invention is curable mixtures of epoxide compounds, which, calculated on the average molecular weight, contain n epoxide groups, where n is a whole number or a fraction greater than 1, tetrahydrofuran and BF, where the mixtures are characterized by the fact that they contain stable complexes of water and/or nitrogen bases with BFs.
Som epoksydforbindelser av den oven-for definerte art som omsettes med tetrahydrofuran kommer f. eks. på tale: epoksyderte diolefiner, diener eller cykliske diener, slik som butadienoksyd, 1,2,5,6-di-epoksyheksan og 1,2,4,5-diepoksycyklo-heksan, epoksyderte diolefinsk umettede karbonsyreestere, slik som metyl-9,10,12,13-diepoksystearat, dimeylesteren av 6,7,10,11-diepoksyheksadekan-l,16-dikarbonsyre, epoksyderte forbindelser med to cyklohek-senylrester, slik som dietylenglykol-bis-(3,4-epoksycykloheksankarboksylat) og 3, 4-epoksycykloheksyilmetyl-3,4-epoksycy-kloheksankarboksylat. Videre basiske poly-epoksydforbindélser, slik som de fåes ved omsetning av primære eller sekundære aromatiske diaminer, slik som anilin eller 4,4'-di- [monometylamino] -dif enyl-metan med epiklorhydrin i nærvær av alkali. As epoxide compounds of the type defined above which are reacted with tetrahydrofuran, e.g. in question: epoxidized diolefins, dienes or cyclic dienes, such as butadiene oxide, 1,2,5,6-diepoxyhexane and 1,2,4,5-diepoxycyclohexane, epoxidized diolefinically unsaturated carboxylic acid esters, such as methyl-9, 10,12,13-diepoxystearate, the dimeyl ester of 6,7,10,11-diepoxyhexadecane-1,16-dicarboxylic acid, epoxidized compounds with two cyclohexenyl residues, such as diethylene glycol bis-(3,4-epoxycyclohexanecarboxylate) and 3, 4-Epoxycyclohexylmethyl-3,4-epoxycyclohexanecarboxylate. Furthermore, basic polyepoxide compounds, such as are obtained by reacting primary or secondary aromatic diamines, such as aniline or 4,4'-di-[monomethylamino]-diphenylmethane with epichlorohydrin in the presence of alkali.
Videre kommer polyglycidylester på tale, slik som de er tilgjengelig ved omsetning av en dikarbonsyre med epiklorhydrin Furthermore, polyglycidyl esters are mentioned, such as are available by reacting a dicarboxylic acid with epichlorohydrin

polyestere kan avledes av alifatiske dikarbonsyrer, slik "som oksalsyre, ravsyre, glu-tarsyre, adipinsyre, pimélinsyre, korksyre, acelainsyre, sebacinsyre og særlig av aromatiske dikarbonsyrer, slik som ftalsyre, isoftalsyre, tereftalsyre, 2,6-naftylendikar-bonsyre, difenyl-o,o'-dikarbonsyre, etylen-glykol-bis-(p-karboksy-fenyl)-eter og an-dre. Det skal nevnes f. eks. diglycidyladipi-nat og diglycidylftalat samt diglycidyles- polyesters can be derived from aliphatic dicarboxylic acids, such as oxalic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, cork acid, azelaic acid, sebacic acid and especially from aromatic dicarboxylic acids, such as phthalic acid, isophthalic acid, terephthalic acid, 2,6-naphthylenedicarboxylic acid, diphenyl -o,o'-dicarboxylic acid, ethylene-glycol-bis-(p-carboxy-phenyl)-ether and others. Mention should be made, for example, of diglycidyl adipinate and diglycidyl phthalate as well as diglycidyl
ter, som tilsvarer den gjennomsnittlige formel ter, which corresponds to the average formula
hvori X betyr en aromatisk kullvannstoff-rest, slik som en fenylrest og Z et helt eller brutt litet tall. Videre kommer det på tale polyglyci-dyletere, slik som de er tilgjengelig ved foretring av en flerverdig alkohol eller po-lyfenol med epiklorhydrin eller diklorhydrin i nærvær av alkali. Disse forbindelser kan avledes av glykoler, slik som etylen-glykol, dietylenglykol, trietylenglykol, propylenglykol-1,2, propylenglykol-1,3, buty-lenglykol-1,4, pentandiol-1,5, heksandiol-1,6, heksantriol-2,4,6, glycerin og særlig a,v polyfenoler, slik som fenol- eller kresol-novolakker, resorcin, pyrokatekin, hydro-kinon, 1,4-dioksynaftalin, bis-[4-oksyf e-nyl] -metan, bis- [4-oksyfenyl] -metylfenyl-metan, bis[4-oksyfenyl]-tolylmetan, 4,4'-dioksydifenyl, bis-[4-oksyfenyl]-sulfon og særlig 2,2-bis[4-oksyfenyl]-propan. Det skal nevnes etylenglykoldiglycidyleter og resor-cinoldiglycidyleter samt diglycidyleter, som tilsvarer den gjennomsnittlige formel hvori X betyr en aromatisk rest og Z betyr et helt tall eller en brøk. Særlig egnet er ved romtemperatur flytende epoksyharpiks, f. eks. slike av 4,4'-dioksydifenyldimetylmetan, hvilke inneholder et epoksydinnhold på ca. 3,8—5,8 epoksydekvivalenter pr. kg. Slike epoksy-harpikser svarer f. eks. til den gjennomsnittlige formel: wherein X means an aromatic carbon hydrogen residue, such as a phenyl residue and Z a whole or broken small number. Also mentioned are polyglycidyl ethers, such as are available by etherification of a polyhydric alcohol or polyphenol with epichlorohydrin or dichlorohydrin in the presence of alkali. These compounds can be derived from glycols, such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol-1,2, propylene glycol-1,3, butylene glycol-1,4, pentanediol-1,5, hexanediol-1,6, hexanetriol -2,4,6, glycerin and especially a,v polyphenols, such as phenol or cresol novolacs, resorcin, pyrocatechin, hydroquinone, 1,4-dioxynaphthalene, bis-[4-oxyphenyl]-methane , bis-[4-oxyphenyl]-methylphenyl-methane, bis[4-oxyphenyl]-tolylmethane, 4,4'-dioxydiphenyl, bis-[4-oxyphenyl]-sulfone and especially 2,2-bis[4-oxyphenyl] - propane. Mention should be made of ethylene glycol diglycidyl ethers and resorcinol diglycidyl ethers as well as diglycidyl ethers, which correspond to the average formula in which X means an aromatic residue and Z means a whole number or a fraction. Liquid epoxy resin at room temperature, e.g. those of 4,4'-dioxydiphenyldimethylmethane, which contain an epoxide content of approx. 3.8-5.8 epoxide equivalents per kg. Such epoxy resins correspond to e.g. to the average formula:
hvori Z betyr et helt tall eller en brøk, f. eks. mellom 0 og 2. where Z means a whole number or a fraction, e.g. between 0 and 2.
Det kan imidlertid også anvendes smel-ter eller oppløsninger av faste epoksyhar-pikser. However, melts or solutions of solid epoxy resins can also be used.
Bortrifluorider kan settes til blandingene som sådant, dog er det fordelaktig på forhånd å overføre det i sine komplekser. Man kan f. eks. først fremstille de stabile komplekser med vann eller kvelstoffbaser. Disse komplekser kan fortynnes med tetrahydrofuran, hvorved det oppstår stabile ikke polymeriserende oppløsninger, hvilke blandes kort før bruken med epoksydforbindelsen. Boron trifluorides can be added to the mixtures as such, however it is advantageous to transfer them in their complexes in advance. One can e.g. first they prepare stable complexes with water or nitrogenous bases. These complexes can be diluted with tetrahydrofuran, whereby stable non-polymerizing solutions are formed, which are mixed shortly before use with the epoxide compound.
Man kan også oppløse BF.s først i et You can also dissolve BF.s first in one
overskudd over den støkiometriske mengde av tetrahydrofuranet som trenges for kompleksdannelsen, og som allerede inneholder den nødvendige lille mengde kvelstoffbase eller vann, f. eks. minst 1 % og hensiktsmessig 2—5 % H2O, beregnet på tetrahydrofuran. excess over the stoichiometric amount of the tetrahydrofuran which is needed for the complex formation, and which already contains the necessary small amount of nitrogenous base or water, e.g. at least 1% and suitably 2-5% H2O, calculated on tetrahydrofuran.
Som moderatorer kan det anvendes kvelstoffbaser som er i stand til å danne stabile komplekser med BF3. Som slike kvelstoffbaser kommer f. eks. på tale: am-moniakk, etylamin, etylendiamin, mono-etanolamin, piperidin, trietanolamin, urin-stoff, heksametylentetramin, trimetylamin, pyridin og særlig aromatiske aminer, slik som anilin, toluidin og Schiff'ske baser av slike aminer. Fortrinnsvis anvender man som moderator enten Schiff'ske baser av aromatiske aminer og aromatiske aldehyder, f. eks. den Schiff'ske base av anilin og Nitrogen bases which are able to form stable complexes with BF3 can be used as moderators. As such nitrogenous bases come e.g. namely: ammonia, ethylamine, ethylenediamine, monoethanolamine, piperidine, triethanolamine, urea, hexamethylenetetramine, trimethylamine, pyridine and especially aromatic amines, such as aniline, toluidine and Schiff's bases of such amines. Preferably, either Schiff's bases of aromatic amines and aromatic aldehydes are used as moderators, e.g. the Schiff's base of aniline and
benzaldehyd eller vann, som danner stabile benzaldehyde or water, which form stable
komplekser med BF.). Bortrifluorid og vann complexes with BF.). Boron trifluoride and water
danner f. eks. stabile, flytende hydrater, slik som BFh . H-O og BF3. 2H2O. Ved anvendelse av vann som moderator forløper forms e.g. stable, liquid hydrates, such as BFh. H-O and BF3. 2H2O. When using water as a moderator precursor
herdningen eksotermt ved romtemperatur. Ved anvendelse av de Schiffske baser av curing exothermically at room temperature. When using the Schiffske bases of
aromatiske aminer og aromatiske aldehyder forløper herdningen først ved varmetilfør-sel, f. eks. etter kort oppvarmning til ca. 60° C eksotermt. Ved romtemperatur foregår herdningen derimot først etter lengre lagring og uten påviselig varmeutvikling, hvilket i visse tilfeller kan være ønsket. Foruten den forsinkende virkning på ko-polymerisas j onshastigheten undertrykker aromatic amines and aromatic aldehydes cure only when heat is applied, e.g. after brief heating to approx. 60° C exothermic. At room temperature, on the other hand, curing only takes place after longer storage and without detectable heat development, which in certain cases may be desired. In addition to the retarding effect on the copolymerization rate, it suppresses
nærværet av små mengder vann dessuten den forstyrrende koagulasjon, hvilket ofte opptrer ved blanding av epoksydforbindelser med en vannfri oppløsning av BF.-i i tetrahydrofuran, og hvilket fører til en ikke homogen herdning. Det kan derfor være av the presence of small amounts of water also interferes with coagulation, which often occurs when mixing epoxy compounds with an anhydrous solution of BF.-i in tetrahydrofuran, and which leads to non-homogeneous curing. It can therefore be off
fordel å anvende vann og kvelstoffbaser sammen som moderatorer. Det gjensidige mengdeforhold mellom epoksydforbindelse og tetrahydrofuran kan variere innen vide grenser. For visse anvendelser kan mengden av tetrahydrofuran være liten og ligge på en slik størrelsesorden som trenges til dannelse av relativt stabile komplekser med BF». Dette tilsvarer f. eks. for det meste et omtrent tidobbelt overskudd av tetrahydrofuran over den støkiometriske mengde som trenges for kompleksdannelsen. Forsøk har vist, at man hensiktsmessig anvender for eksempel 5 deler av en slik oppløsning av 10 % bortrifluorid i tetrahydrofuran pr. 100 deler av en polyglycidyleter av 4,4'-dioksydifenyldimetylmetan med et epoksydinnhold på 4,03 epoksydekvivalenter pr. kg dvs. 1,25 g bortrifluorid pr. gramekvi-valent epoksydgrupper. advantage to use water and nitrogen bases together as moderators. The mutual quantity ratio between epoxide compound and tetrahydrofuran can vary within wide limits. For certain applications, the amount of tetrahydrofuran can be small and be of the order of magnitude needed to form relatively stable complexes with BF". This corresponds to e.g. mostly an approximately tenfold excess of tetrahydrofuran over the stoichiometric amount needed for complexation. Experiments have shown that it is appropriate to use, for example, 5 parts of such a solution of 10% boron trifluoride in tetrahydrofuran per 100 parts of a polyglycidyl ether of 4,4'-dioxydiphenyldimethylmethane with an epoxide content of 4.03 epoxide equivalents per kg, i.e. 1.25 g boron trifluoride per gram-equivalent epoxide groups.
Ifølge en foretrukken utførelsesform for oppfinnelsen, anvendes større mengder tetrahydrofuran, idet mengdeforholdet epoksydforbindelse: tetrahydrofuran ut-gjør ca. mellom 100 : 5—50 og fortrinnsvis 100 : 10—30. Hensiktsmessig anvender man pr. epoksydekvivalent for epoksydforbindelsen høyst 1 mol tetrahydrofuran. According to a preferred embodiment of the invention, larger amounts of tetrahydrofuran are used, the quantity ratio of epoxide compound: tetrahydrofuran being approx. between 100 : 5-50 and preferably 100 : 10-30. Appropriately, one uses per epoxide equivalent for the epoxide compound at most 1 mol of tetrahydrofuran.
Mengden av det vann som anvendes som moderator eller av kvelstoffbasen, kan likeledes variere innen visse grenser. Virk-somme er allerede mindre mengder enn det som støkiometrisk er nødvendig for dannelse av 1 : 1 komplekset med BFa. The amount of water used as moderator or of the nitrogen base can likewise vary within certain limits. Active amounts are already smaller than what is stoichiometrically necessary for the formation of the 1:1 complex with BFa.
Ved den foretrukne anvendte kombi-nasjon bortrifluorid-vann anvender man på 1 vektsdel bortrifluorid hensiktsmessig minst ca. 0,2, fortrinnsvis 0,5—3 vektsdeler vann. In the preferred combination of boron trifluoride and water, 1 part by weight of boron trifluoride is suitably used at least approx. 0.2, preferably 0.5-3 parts by weight of water.
De herdbare blandinger ifølge oppfinnelsen kan videre inneholde egnede mykgjørere eller inerte fortynningsmidler. En tilsetning av mykgjørere, slik som dibutylftalat, dioktylftalat, tricresylfosfat eller trifenylfosfit, gir mykere, mere elastiske og fleksible herdede masser. Det kan videre være fordelaktig, alt etter de egenskaper som ønskes av den herdede harpiks, å medanvende aktive fortynnings- eller modifi-seringsmidler, hvilke reagerer under virk-ningen av BF-t med epoksydharpiksen og deltar i herdningsreaksjonen, f. eks. etyl-enisk umettede polymerisasjonsegnede forbindelser, slik som styrol, monoepoksydfor-bindelser, slik som kresylglycid. Videre kan der også innføres mono- eller fordelaktig polyfunksjonelle forbindelser, hvilke inneholder hydroksylgrupper, ketogrupper, al-dehydgrupper, karboksylgrupper etc. slik som f. eks. to- eller flerverdige alkoholer, polyglykoler, polyester med innestående hydroksyl- eller karboksylgrupper under innvirkning av bortrifluoridet. The curable mixtures according to the invention may further contain suitable plasticizers or inert diluents. An addition of plasticisers, such as dibutyl phthalate, dioctyl phthalate, tricresyl phosphate or triphenyl phosphite, gives softer, more elastic and flexible hardened masses. It can also be advantageous, depending on the desired properties of the cured resin, to co-use active diluents or modifiers, which react under the action of BF-t with the epoxy resin and participate in the curing reaction, e.g. ethylenically unsaturated compounds suitable for polymerization, such as styrene, monoepoxide compounds, such as cresyl glycide. Furthermore, mono- or advantageously polyfunctional compounds can also be introduced, which contain hydroxyl groups, keto groups, aldehyde groups, carboxyl groups, etc. such as e.g. di- or polyhydric alcohols, polyglycols, polyester with contained hydroxyl or carboxyl groups under the influence of boron trifluoride.
Det ligger videre innenfor rammen for foreliggende oppfinnelse å medanvende i de beskrevne masser vanlige tilsetninger, slik som akseleratorer, slik som styroloksyd eller organiske peroksyder, pigmenter, strekkmiddel og fyllmiddel. Som strekk- og fyllmiddel kan det f. eks. anvendes asfalt, bitumen, glassfibre, glimmer, kvartsmel, kaolin eller finfordelt kiselsyre (AEROSIL) eller aluminiumpulver. Derved kan man f. eks. forarbeide en oppløsning av komplekset av BF3 og vann eller kvelstoffbase i tetrahydrofuran med det anorganiske fyllstoff til en herdet pasta, og blande denne kort før bruken med epoksydharpiksen eller en blanding av epoksydharpiksen og tetrahydrofuran. It is also within the scope of the present invention to co-use common additives in the described masses, such as accelerators, such as styrene oxide or organic peroxides, pigments, extenders and fillers. As a stretching and filling agent, it can e.g. asphalt, bitumen, glass fibres, mica, quartz flour, kaolin or finely divided silicic acid (AEROSIL) or aluminum powder are used. Thereby, one can e.g. processing a solution of the complex of BF3 and water or nitrogen base in tetrahydrofuran with the inorganic filler into a hardened paste, and mixing this shortly before use with the epoxy resin or a mixture of the epoxy resin and tetrahydrofuran.
Blandingen ifølge oppfinnelsen kan tjene til fremstilling av hurtigherdende klebemidler, lamineringsharpikser, lakkovertrekk, støpeharpikser og pressmasser. The mixture according to the invention can be used for the production of fast-setting adhesives, lamination resins, varnish coatings, molding resins and pressing compounds.
Blandinger ifølge oppfinnelsen, hvilke dessuten inneholder pigmenter og fyllstof-fer av enhver art, slik som finfordelt kiselsyre, samt mykgj ørere, egner seg fremrag-ende som utfylling- og sparkelmasser. Mixtures according to the invention, which also contain pigments and fillers of all kinds, such as finely divided silicic acid, as well as softeners, are excellently suitable as fillers and fillers.
Eksempel 1: Example 1:
67,8 g bortrifluorid-gass innledes under iskjøling i 36 g vann. 15,3 g av det dannede bortrifluoriddihydrat, hvilket inneholder 10 g bortrifluorid, fylles opp med tetrahydrofuran til 100 cm<3>. Den erholdte oppløsning av bortrifluorid-vann-tetrahy-drofurankompleks forblir vannklar og ube-grenset holdbar. Det finner ikke sted noen polymerisasjon av tetrahydrofuranet. 5 g av denne oppløsning og 15 g tetrahydrofuran blandes med 100 g av en på kjent måte ved alkalisk kondensasjon av 4,4'-dioksydfenyldimetylmetan og epiklorhydrin fremstillet flytende epoksydharpiks med et epoksydinnhold på 5,2 epoksydekvivalenter pr. kg. Blandingen herder ved 20° C etter 3 minutter under varmeutvikling.

75 g av den epoksydharpiks som ble anvendt i eksempel 1 oppvarmes sammen med 4,5 g av et bortrifluoridmonoetylamin-kompleks i 4 min. ved 20° C til 135° C så-ledes at herderen oppløses klart. Nu lar man det straks avkjøle igjen til 30° C og tilsetter under god omrøring 25 g tetrahydrofuran. 75 g of the epoxy resin used in example 1 is heated together with 4.5 g of a boron trifluoride monoethylamine complex for 4 minutes. at 20° C to 135° C so that the hardener dissolves clearly. Now it is immediately allowed to cool again to 30° C and 25 g of tetrahydrofuran is added with good stirring.
Blandingen ifylles deretter i en auto-klav og oppvarmes i 14 timer til 150° C. Man får et fjærhårdt, gulaktig farget poly-merisat, som i vakuum (20 mm Hg) ved opphetning til 100° C i 23 timer taper 7 % av sin utgangsvekt. The mixture is then filled into an autoclave and heated for 14 hours to 150° C. A spring-hard, yellowish colored polymer is obtained, which in vacuum (20 mm Hg) when heated to 100° C for 23 hours loses 7% of its starting weight.
Utsettes tetrahydrofuranet (25 g) for BF:i-monoetylaminkomplekset (1,125 g) alene for de ovenstående betingelser inntrer det en polymerisasjon. If the tetrahydrofuran (25 g) is exposed to the BF:i-monoethylamine complex (1.125 g) alone under the above conditions, polymerization occurs.
Eksempel 9: Example 9:
80 g av den epoksydharpiks som an-vendtes i eksempel 1 med et epoksydinnhold på 5,2 g epoksydekvivalenter pr. kg harpiks, oppvarmes sammen med 20 g av en epiklorhydrin og 4,4'-dioksydifenyldime-tylmetan med et epoksydinnhold på 3,8 epoksydekvivalenter pr. kg til 120° C og deri oppløses 5 g av et kondensasjonsprodukt av 1 mol oktadecylalkohol og ca. 35 mol etylen-oksyd. Nu lar man avkjøle til 60° C og tilsetter under god omrøring 15 g destillert vann. Det dannes straks en emulsjon som er stabil ved romtemperatur og som har en pastaformet konsistens. 20 g av denne blanding tilsettes nu 2,0 cm<3> av en 10 volumprosent BF3-herde-oppløsning som man får når man fortynner 15,4 g BF;f-dihydrat (65 % BF3) med tetrahydrofuran til 100 cm<3>. 80 g of the epoxy resin used in example 1 with an epoxy content of 5.2 g epoxy equivalents per kg of resin, is heated together with 20 g of an epichlorohydrin and 4,4'-dioxydiphenyldimethylmethane with an epoxide content of 3.8 epoxide equivalents per kg to 120° C and 5 g of a condensation product of 1 mol of octadecyl alcohol and approx. 35 moles of ethylene oxide. Now allow to cool to 60° C and add 15 g of distilled water while stirring well. An emulsion is immediately formed which is stable at room temperature and has a paste-like consistency. 20 g of this mixture is now added to 2.0 cm<3> of a 10 volume percent BF3 hardening solution which is obtained when 15.4 g of BF;f-dihydrate (65% BF3) is diluted with tetrahydrofuran to 100 cm<3 >.
Den katalyserte emulsjonspasta ut-strykes nu i et tynt lag på en glassplate og tørkes. Det fremstilte overtrekk herder ved romtemperatur innen 45 min., idet man gjør den iakttagelse at herdningen inntrer først der hvor vannet fordunster, dvs. blandingen herder først fra overflaten. Dette betinger at det påførte overtrekk ikke på-føres for tykt da vannet i de nedre lag ikke lenger kan fordunste innen en rimelig tid. The catalyzed emulsion paste is now spread in a thin layer on a glass plate and dried. The produced coating hardens at room temperature within 45 min., making sure that the hardening occurs first where the water evaporates, i.e. the mixture hardens first from the surface. This requires that the applied coating is not applied too thick, as the water in the lower layers can no longer evaporate within a reasonable time.
Ved 60° C forelå herdningen allerede innen 15 min. Brukstiden for den katalyserte blanding utgjør ved romtemperatur ca. 5 timer. At 60° C, the hardening was already within 15 min. The useful life of the catalyzed mixture at room temperature is approx. 5 hours.
