ABSTRACT:
Compounds useful for improving the intra-film binding of micaceous particulates in films formed from coating compositions which contain such micaceous particulates comprise urethanes or ureas which are the reaction products of silylalkyl- or silylaryl isocyanates with blocked or unblocked alcohols, aminoalcohols, or polydiol alcohols. The compounds may also be the reaction products of silylalkyl- or silylarylamines with half-blocked diisocyanates which are themselves the reaction products of a diisocyanate with a blocked or unblocked alcohol, aminoalcohol, or polydiol alcohol.
Micaceous particulates which have been surface modified by reaction with these compounds, as well as coating compositions comprising such surface-modified micaceous particulates, and coated substrates are also disclosed.
