POLYMERIC COMPOSITION FOR COATINGS Russian patent published in 2002 - IPC

FIELD: polymeric compositions for protective coatings hardenable under natural conditions at relative humidity of up to 100%. SUBSTANCE: composition comprises, wt parts: epoxydiane resin, 48.0-69.8; ketimine hardener, 22.3-40.1; 2, 4, 6-tris(dimethylaminomethyl)phenol accelerator, 2.6-2.8; photoinitiator which is mixture of benzoin esters, 0.7-1.2 and comonomer which is triethylene glycol dimethaacrylic ester, 4.5-8.0. Ketimine hardener is product of reaction of ketimine based on diethylene triamine or triethylene tetramine with isocyanate adduct and unsaturated compound. Invention makes it possible to prepare coatings having low swelling ability, high wear resistance, cavitation stability, low corrosion rate and high degree of hardening. EFFECT: improved properties of the polymeric composition. 96 ex, 3 tbl
