Abstract
Abstract Disclosed is an adduct of a mercapto-functional monohydric alcohol and a vinyl-type silane having at least one hydrolyzable group directly attached to a silicon atom, the adduct prepared by reacting the mercapto-functional monohydric alcohol and the vinyl-type silane in the presence of a free radical initiator. Also disclosed is an NCO-functional compound comprising the reaction product of: (A) the aforesaid adduct of a mercapto-functional monohydric alcohol and a vinyl-type silane having at least one hydrolyzable group directly attached to a silicon atom, and (B) an organic polyisocyanate.
