Properties of Epoxy Cathodic Electrodeposition Coating by Aminosiloxane

Article Preview

Abstract:

The epoxy cathodic electrodeposition (CED) coating modified by organic siloxane has been prepared. EP-44 resin was modified by aminosiloxane and organic amine, then to be neutralized with organic acid and emulsified in deionized water with blocked isocyanate as curing agent. The CED films were electrodeposited on tinplate, and the properties of the paint films were investigated. The results indicated that the films shown good performance.
