ABSTRACT:
A primer composition suitable for metallic substrates, which primer comprises a hydrogenated elastomeric block copolymer having resinous endblocks, the copolymer being functionalized by treatment with an unsaturated monomer such as maleic anhydride. The primer composition further comprises an endblock compatible resin such as an aromatic resin. Such compositions are especially useful for priming metal which is later to be fabricated into channels and frames. Thus, it is of particular utility in the construction of double glazed insulated windows.
