Cathodic electrodeposition coatings containing zinc hydroxyphosphite pigment |
摘要 |
An improved aqueous electrocoating composition having a binder of an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent; wherein the improvement is the use of zinc hydroxyphosphite pigment as a corrosion inhibitive pigment and an as a curing catalyst which provides an excellent cure under overbake and underbake conditions and forms a coating with excellent chip resistance and the throwing power of the electrocoating composition is significantly improved.
