Definitions
- the present invention relates to a specific uretdione prepolymer, and an aqueous curable composition based on the specific uretdione prepolymer. Furthermore, it pertains to a process for curing said aqueous curable composition, the cured article obtained by this process and additionally to the use of said aqueous composition for coatings, adhesives and/or sealants.
- Aqueous curable compositions based on specific uretdione prepolymers are for example known from DE 10 2005 036 654 Al. However, those compositions do not show a sufficient long-term stability. The hydrophilization of the polymer is obtained via ionogenic groups.
- an object of the present invention to provide an uretdione prepolymer, which provides an improved aqueous curable composition, which shows improved, preferably long-term, storage stability.
- An uretdione prepolymer which comprises at least one uretdione group, and which is obtainable by reacting
- At least one polyalkoxy ether derivative comprising at least two -OH groups, which are present on two different non-neighbouring atoms of the molecule and whereby at least one of the -OH groups is not a terminal -OH group,
- At least one reactant which comprises at least one Zerewitinoff-active group and being different from A2 or which is 3 ⁇ 40,
- the prepolymer has an acid number of at most 4 mg KOH/g, preferably determined according to DIN EN ISO 2114:2002-06 as 37 wt.% aqueous dispersion.
- the uretdione prepolymer of the present invention When the uretdione prepolymer of the present invention is employed in aqueous curable compositions, the thus obtained compositions are homogenous after storage over a long time, can retain a high amount of uretdione groups, compared to the initially used ones, the uretdione groups can be reacted with alcohols or amines, whereby a crosslinking of the prepolymers is obtained, the reaction of the uretdione group with alcohol can be catalysed and the cured product obtained by these compositions show equivalent or even improved lacquer properties.
- the use of compounds A2 in the preparation of the prepolymer leads to this properties, since it promotes chain growth and provides a better cross-linking
- any numerical range recited herein is intended to include all sub-ranges subsumed therein.
- a range of " 1 to 10" is intended to include all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.
- a "monomer” is a low-molecular weight compound comprising functional moieties, wherein said monomer functions as a building block for polymers and has a defined molecular weight.
- a polymer according to the present invention is a compound, comprising in its molecular structure at least one repeating unit, which was integrated in the polymer structure during polymer synthesis by repeatedly linking monomers together via covalent bonds to form said polymer structure.
- the number average molecular weight is preferably at least 250 g/mol, more preferably at least 1,000 g/mol.
- polymer includes homopolymers, copolymers, block-copolymers and oligomers.
- a "prepolymer” is a polymer with reactive groups.
- the molecular structure of a prepolymer is formed by repeatedly linking more than two monomers of the same of different kind together.
- the prepolymer can participate in a subsequent formation of a polymer, which has a higher molecular weight than said prepolymer.
- the term“prepolymer” encompasses polymers, which are able to chemically react via at least one of its reactive groups, forming a repeating unit of a (preferably crosslinked) polymer. Therefore the term answeringprepolymer“ encompasses as well self-crosslinking polymers with at least two different kinds of reactive groups, wherein said groups are able to chemically react among themselves, so that the prepolymer molecules are able to crosslink.
- the average molecular weight is defined as the number average molecular weight Mn.
- Mn is determined via gel permeation chromatography (GPC at 23°C) in tetrahydrofurane as the solvent.
- An epichoic compound contains at least one moiety, comprising a carbon-hydrogen covalent bond.
- ⁇ is defined as non-aromatic hydrocarbyl groups being saturated or unsaturated.
- the term “unaraliphatic” is defined as hydrocarbyl moieties composed of a non-aromatic, as well as saturated or unsaturated hydrocarbyl group, which is directly bonded to an aromatic moiety.

- the aqueous, curable composition may be applied uniformly to a substrate, for example by spin coating, dip coating, knife coating, curtain coating, brushing, spraying—especially electrostatic spraying— and reverse roll coating.
- Said coating compositions can be used as a primer, color coat or as a clear coat.
- the choice of diluent and the concentration depend predominantly on the choice of coating ingredients and the coating process.
- the diluent should preferably be inert. In other words, it should not undergo any chemical reaction with the components and should be capable of being removed after the coating operation in the curing process. Surprisingly it was found, that especially water is an appropriate diluent.
- Suitable diluents are water, ketones, ethers and esters, such as methyl ethyl ketone, isobutyl methyl ketone, cyclopentanone, cyclohexanone, N-methylpyrrolidone, dioxane, tetrahydrofuran, 2-methoxy ethanol, 2-ethoxy ethanol, l-methoxy-2-propanol, 1 ,2-dimethoxy ethane, ethyl acetate, n-butyl acetate and ethyl 3-ethoxypropionate. It is particularly preferred to use water as diluent.

- the deposited aqueous, curable composition is preferably exposed to a temperature of 60 to 120°C, preferably 80 to 100°C, to cure said deposited curing composition.
- the deposited aqueous, curable composition is preferably exposed to said temperature for a period of 20 to 45 minutes to cure said deposited curing composition. It is particularly preferred to expose the deposited aqueous, curable composition to a temperature of 60 to 120°C, preferably 80 to 100°C, for a period of 20 to 45 minutes.
- the cured, aqueous curable composition by preheating the deposited, curable composition to a temperature of 30°C to below 60°C for a period of 2 to 10 minutes. Said preheating is particularly preferred followed by increasing the temperature to 60 to 160°C (preferably to 60 to 120°C, most preferred to 80 to 100°C) and exposing for another period of 20 to 45 minutes at said increased temperature.
- the preheating step is advantageous, since the amount of water is reduced in the deposited, curable composition prior to curing. The subsequent curing reaction at 60°C to 160°C is thereby enhanced.
- the cured aqueous curable composition forms a crosslinked film on the substrate, preferably forms a transparent solid on the substrate, that shows excellent mechanical and optical properties and a high resistance against chemicals and solvents.
- Ymer N120 (CAS number: 131483-27-7), a linear, trimethylolpropane started polyethylene glycol monomethyl ether, OH number 100-120 mg KOH/g) was acquired from Perstorp Holding AB, Malmo, Sweden.

After 20 h, the reaction mixture, which had an NCO content of 28.7%, corresponding to a degree of oligomerization of 21.8%, was freed from volatile components without prior addition of a catalyst poison with the aid of a thin-film evaporator at a temperature of 160 ° C and a pressure of 0.3 mbar.
- DMAP 4-dimethylaminopyridine
- the solids contents were determined by heating a weighed sample (approx lg) at 105 °C to constant weight. At constant weight, the solid-body content is calculated by reweighing the sample.
- the pendulum hardness by the Konig method was measured on a glass plate according to DIN EN ISO 1522:2007-04.
- NCO contents were determined volumetrically in accordance with DIN-EN ISO 11909:2007-05.

- the average particle sizes (the number-average is given) of the polyurethane dispersions were determined following dilution with deionized water by means of laser correlation spectroscopy (instrument: Malvern Zetasizer 1000, Malver Inst. Limited, London, UK).
- Zeta potential was measured by diluting one drop of the sample with 20 ml demineralized water and homogenized by stirring. Subsequently the zeta potential is determined at 23°C in the Malvern Nanosizer ZS90" (Malvern Instruments,dorfberg, Germany).
- Acid number of the respective dispersion was determined according to DIN ISO 2114 1:2006-11. Instead of a mixture of toluene and ethanol - as described in DIN ISO 2114 1:2006-11- a mixture of acetone and ethanol (2: 1 by weight) was used as solvent. The unit of the acid number is mg KOH per g of the analyzed sample.
- the cured coating films were tested for their resistance to xylene and water.
- a piece of cotton wool soaked with the test substance was placed on the coating surface and covered with a watch glass. After the specified exposure time, the cotton wool was removed; the exposed site was dried and immediately inspected.
- the evaluation of the softening or discoloring of the coating surface was carried out following the DIN EN ISO 4628-1 :2016-07:
- the uretdione ring opening was characterized by an FT-IR spectrometer (tensor P with Platinum ATR unit (diamond crystal) from Bruker). The spectra were recorded in a wave number range of (4000-400) cm 1 . The maximum of the uretdione peak (about 1760 cm 1 ) was evaluated. Peak heights to comparative systems were compared with an initial value set to 100% (uretdione film without catalyst, dried at room temperature) and variations relative to this (ratio formation). Uretdione peak height of films cured for 30 min at 180 °C were set to 0%. When measuring on an ATR crystal, the intensity of the spectrum depends on the occupation of the crystal surface.
