Abstract
A corrosion resistant, alkali resistant coating composition is disclosed. The composition comprises a binder comprising a reaction product of an epoxy-containing material and a phosphorus-containing material together with a curing agent. Aminoplasts, especially melamine-based aminoplasts, are particularly suitable curing agents. A source of silicon can optionally be included. The compositions also provide excellent adhesion and can be used with or without a weldable primer. The compositions are applied to and cured on a metal substrate.

39. A weldable, corrosion resistant layer deposited on a substrate, wherein the weldable layer is of a thickness to provide corrosion resistance without inhibiting welding, is substantially free of conductive pigments, and is comprised of the cured reaction product of:
-
a) the reaction product of at least one epoxy-functional material and at least one phosphorus-containing material; and
b) a curing agent - View Dependent Claims (40, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)
