Layer of reaction product of epoxy and phosphorus materials and curing agent on substrate
First Claim
1. A weldable, corrosion resistant layer deposited on a substrate, wherein the weldable layer has a thickness of from 0.1 micron to 1.0 micron, 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, wherein the equivalent ratio of the phosphorous-containing material to epoxy-containing material is within the range of 1.6;
1 and 5;
1; and
b) a curing agent.

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.
