SELF-CROSSLINKABLE ELECTROCOAT RESINS PREPARED BY ROOM TEMPERATURE REACTIONS OF EPOXY RESINS AND FATTY AMIDOPOLYAMINES

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 an epoxy resin with amidopolyamine fat close to room temperature.in such a way as to form a partially cross-linked resin, in which at least 50% of the amine groups have been neutralized with an acid soluble in water.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.
