RADIATION CURABLE ADHESION PROMOTER

摘要

This invention relates to a new type of adhesion promoter, which in particular can be used in radiation curable coatings and adhesives. This adhesion promoter is obtained by fast reaction of alkoxysilanes containing mercapto groups, with monomers containing two or more acrylate or methacrylate groups, in the presence of organic amines under mild conditions. This adhesion promoter has adhesion promotive functional groups such as alkoxysilanes at one end, and polymerable groups of (meth)acrylate at the other end. The invention can be applied to coatings, inks and adhesives to improve adhesion between cured materials and substrates.
