AI Technical Summary

Problems solved by technology

The use of isocyanate dimer-containing components therein resulted in improved interlayer adhesion, but in this cited example, no effect on the hardness and scratch resistance of the coating (Examples 3, 4 and V2)
No examples are given of coating properties using only thermal curing without radiation curing (i.e. simulating shadowed areas)

[0086] A1) Polyester Production

[0087] Adipic acid (292 g) and butanediol (295 g) were melted in a 21 flask with a distillation head under nitrogen flow. When the temperature reaches 160°C, water starts to distill out. The temperature was continuously raised to 220°C over a period of 1 hour. After 4 hours at this temperature, the separation of water slowed down. 200 mg of FASCAT 4102 (transesterification catalyst from Arkema) were incorporated with stirring and the operation was continued under reduced pressure, which was adjusted during the reaction so that distillate produc...

Abstract

The present invention relates to dual cure formulations with components comprising uretdione groups. The present invention relates to novel formulations that can be cured thermally and by actinic radiation, referred to as dual cure formulations. Furthermore, the present invention relates to the use of the novel formulations that can be cured thermally and by actinic radiation for the production of pigmented and pigment-free paints and for adhesives and sealants.

Description

technical field [0001] The present invention relates to novel formulations which are thermally curable and which can be cured by means of actinic radiation, so-called dual-cure formulations. The invention also relates to the use of the novel thermally curable and actinic radiation-curable formulations for the production of colored or clear paints or adhesives and sealants. Background technique [0002] Formulations curable by actinic radiation are known. [0003] Ethylenically unsaturated prepolymers are described e.g. in P.K.T. Oldring (ed.), "Chemistry and Technology of UV-and EB-Formulation for Coatings, Inks and Paints", Vol. II, SITA Technology, London 1991, e.g. based on epoxy acrylic esters (pp. 31-68), urethane acrylates (pp. 73-123) and melamine acrylates (pp. 208-214). Such formulations are also frequently mentioned in the patent literature, examples that may be mentioned are JP 62110779 and EP 947 565 . [0004] Coating of metal substrates is a particular probl...
