SOLUTION POLYMERIZED VINYL RESIN FOR PRIMER APPLICATIONS

摘要

The invention relates to a primer for covering a metal surface such as the surface of steel, galvanized steel or aluminium, the primer comprising polymer chains to protect the metal surface and hydrolysable adhesion promoters to enhance the metal affinity of the primer, to a method of producing such a primer, and to the use thereof. According to the invention, the polymer chains comprise building blocks formed from vinyl monomers and linked together in the form of chains, a fraction eta hy of the building blocks having a functional pendent group comprising a hydrolysable adhesion promoter. This provides a primer on the basis of polymers whose synthesis has substantially taken place in its entirety before the primer is applied. All the vinyl monomers are incorporated in the polymer chain as randomly as possible, although they need not all be equally reactive. The primer according to the invention provides a large degree of freedom in conferring desired characteristics.
