SELF-CROSSLINKABLE ELECTROCOAT RESINS PREPARED BY ROOM TEMPERATURE REACTIONS OF EPOXY RESINS AND POLYAMINES CONTAINING PRIMARY AND TERTIARY AMINE GROUPS.

摘要

coating compositions comprising a cathode by electrodeposition, self cross linkable aqueous dispersion resin.this is a self cross linkable resin and epoxide and amine function is prepared by reacting a polyamine with an epoxy resin at about room temperature.at least 50% of the amine groups have been neutralized with an acid soluble in water. the polyamine contains at least one primary amino group and at least one tertiary amine.the partially cross-linked resin may be deposited on a metal substrate in the bath to be polymerized at high temperature.in order to form a coating with excellent corrosion protection and excellent adhesion with a substrate.
