HYBRID PAINT COMPOSITION

PROBLEM TO BE SOLVED: To provide a paint composition with improved in high hardness, abrasion resistance and chemical resistance, and high flexibility. SOLUTION: The hybrid paint composition contains 5-80 wt.% of (A) an aliphatic polyisocyanate-aminosilane adduct which is a reaction product of (A1)...

Summary:PROBLEM TO BE SOLVED: To provide a paint composition with improved in high hardness, abrasion resistance and chemical resistance, and high flexibility. SOLUTION: The hybrid paint composition contains 5-80 wt.% of (A) an aliphatic polyisocyanate-aminosilane adduct which is a reaction product of (A1) a polyisocyanate component having an isocyanate content of 9-50 wt.% and comprising an aliphatic polyisocyanate with (A2) at least 0.7 amino- equivalent, based on the NCO equivalent of (A1), of an aminosilane of formula I: (RO)nY3-nSi-CH2CH2CH2-NHZ (wherein R and Y are each methyl and/or ethyl; Z is H, a 1-12C alkyl or the like; and n is 1, 2 or 3) and occasionally (A3) an isocyanate-reactive compound other than (A2), and 20-95 wt.% of (B) at least one hydrolyzable silane of formula II: QSi(OX)3 (wherein X is a 1-4C alkyl; and Q is H, a 1-8C alkyl or phenyl) or the like and/or a hydrolyzate/ condensate obtained from these silanes.
