HEAT-ACTIVATED PAINT COMPOSITION Russian patent published in 2007 - IPC C08L63/00 C09D163/00 C09J163/00 C09D175/04 C09D5/08 C08J5/24 

FIELD: thermo-setting heat-activated paint compositions, application of such composition on substrate.

SUBSTANCE: proposed composition contains at least one amorphous binder at T_s below 5C and/or at least one crystalline or semi-crystalline binder at melting point or interval of melting points below 150C, at least one epoxy resin, at least one polyamine including cyanamide groups, at least one blocked or latent catalyst in the amount of 0.5-5 mass-%; this catalyst is deblocked or activated at elevated temperature below hardening temperature of paint composition. Paint composition is characterized by T_s below 5C and viscosity below 2000 mPa·sec measured at temperature of 80C and shift rate of 10 c^-1. The method of application of coat to substrate includes the following stages: first, paint composition is heated to temperature of application, then, composition is applied on substrate and paint thus applied is heated to temperature of its hardening till complete hardening. Paint composition is used for application onto mirror reverse surface, onto metal surface or onto substrate sensitive to heating. This composition forms thin anti-corrosive coat free from volatile organic compounds which may be used at temperature of application between 100 and 160C by employing the methods of application at low temperatures.

EFFECT: enhanced efficiency.
