Abstract:
Disclosed is a composition comprising: a) an condensate of one or more aminohydrocarbyl alkoxy silanes and one or more alkenyl alkoxy silanes; b) one or more mercaptohydrocarbyl alkoxy silanes; and c) water; wherein the composition is useful as a primer useful with adhesives or coatings containing polymers having isocyanate functional groups, alkoxysilane functional groups or both. The composition may include one or more epoxyhydrocarbyl silanes. The composition may include one or more alkanols in sufficient amount to improve the volatilization of the liquid components away from substrate surface.
