Abstract
The present invention relates to water-borne emulsion adhesives based on polymers or copolymers of vinyl acetate and having uniformly dispersed therein an adhesion promoter consisting essentially of an alkoxysilane and up to about 80% by weight of a plasticizer for the poly(vinyl acetate). The alkoxysilane useful herein may be selected from ##STR1## in which R is independently selected from alkyl or alkoxyalkyl radicals having 1-4 carbon atoms. The modified adhesives have improved bond strength to wood, particularly after exposure to moisture.
