Abstract
Compounds useful for improving the dispersibility of micaceous particulates in aqueous-based coating compositions comprise urethanes or ureas which are the reaction products of silylalkyl or silylaryl isocyanates with alcohols, amines, polyether alcohols or amine-terminated polyethers. 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 an alcohol, amine, polyether alcohol or amine-terminated polyether. 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.
