Definitions
- Paints are also in continuous development and the old paints based on solvents and more and more dropping in demand have been replaced firstly by high dry paints, that is to say with less solvent, and then by watersoluble and powder paints, which are continuously on the increase and development. These latest paints have the good quality of being totally used and without waste because the application excess can be recovered and used again.
- thermoplastic paints have been replaced by thermosettable ones with different types of polymers and several crosslinkable or thermosettable systems and with lower and lower crosslinking time and temperatures.
- Powder paints in various crosslinking systems generally give high glossy coatings with good chemical-physical features such as flexibility, hardness and resistance to chemicals and weather agents with gloss being equal to or above 90% when measured under an angle of 20° or 60° according to rule ASTM D 523.
- FR 78 04 685 discloses mat films which are obtained by a powder paint consisting of intimate mixture in an extruder of two hydroxyl resins having different hydroxy number along with polyanhydridic hardener.
- DE 23 24 696 discloses mat films obtained by a powder paint consisting of intimate homogenizalion in extruder of a glycidic or epoxydic resin along with anhydridic salts of polycarboxylic acids.
- DE 32 32 463 discloses mat films obtained by a powder paint consisting of intimate mixture of a hydroxyl polyester resin along with a blocked isocyanic hardener containing carboxylic aci s and a co-crosslinker containing glycidylic groups.
- JP 101963 of August 25, 1 977 discloses mat films obtained by an eutectic mixture of two paints in epoxydic powder having different reactivity and obtained by the same epoxydic resin but catalized with different amounts of the same catalyst.
- EP 0 551 064 A2 of UCB powder paint compositions for mat materials obtained by coextrusion of a linear carboxylic polyester with acid value between 20 and 50 mg of OH and an acrylic polymer containing from 5 to 30% of glycidic methacrylate are claimed.
- thermosensitivc supports we have devoted a great part of our research in order to both find out application methods meeting these requirements as claimed in our Italian patent application Ml 96A 001728 concerning a method of hot air application of thermomeltable powder polymers and obtain unsaturated powder polymers to be used as hardenable paints by means of radiations or catalysts soon after the application and melting.
- MI 96A 001097 we obtained as much as we had set but the problem relating to manner of obtaining mat powder paints derived from these unsaturated products was not solved
- powder paints which are satin or mat by using binder systems containing unsaturated polymers, can be obtained by dry blending (dry blend) or coextruding two or more compositions different from each other both for physical appearance (amorphous or crystalline) and for unsaturated functional groups (the one with a few and the other with a lot) by means of two or more adiacent extruders with a single exit nozzle A maximal opacity is obtained with a 1 1 ratio by weight between the two mixtures
- Ciystalline unsaturated polyester 03489 of Vianova Resins with melting point 130 140°C and unsaturation degree of equivalent weight ⁇ 550 Examples. In the formulations all parts are by weight unless otherwise specified.
- Additol VXL9824 stretching master agent, trademark registered by Vianova Resins.
- Photoinitiator e.g. lrgacure 651 and lrgacure 1800 registered by Ciba.
- Peroxide e.g. Dicumyl-peroxide Formulations of the above described examples were extruded by means of twin screw extruder under the following conditions: - T(°C): 80- 100- 100
- Blends at 1 : 1 ratio by weight are carried out between the paints formulated (dry blend) in each mixture.
