RADIATION CURABLE ADHESION PROMOTER

摘要

New type of adhesion promoter in particular can be used in radiation curable coating material, adhesive and ink. This adhesion promoter is obtained by fast reaction of alkoxysilane containing isocyanate, with acrylate or methacrylate monomers containing hydroxyl or amino groups, in the presence of dibutyltin dilaurate catalyst at a temperature 40-60°C. This adhesion promoter has adhesion promotive functional groups such as alkoxysilanes at one end, and polymerisable groups of (meth)acrylate at the other end. This invention can be applied to coating material, adhesive and ink to improve adhesion between cured materials and substrates.
