METHOD FOR IMPROVING THE ADHESION OF POLYESTER COMPOSITIONS

摘要

This invention relates to a method of improving the adhesion of a polyester composition to itself or to metals. This is achieved by treating the surface of the polyester composition with a treating agent preferably in a solvent to enhance the bond strength between isocyanate-type adhesives and the surface of the polyester composition. The treating agent is a tertiary amine of the aliphatic, cycloaliphatic and aromatic-type.
