An aqueous electrodeposition coating composition comprising a cathodically electrodepositable binder, the binder comprising a phosphorylated resin and a carboxyl group separated by from 2 to 4 carbons from an ester group, provides corrosion protection equivalent to that obtained by the conventional phosphate pretreatment-electrodeposition coating process.

Electrocoat composition and process replacing phosphate pretreatment

A coating composition, such as an electrodepositable electrocoat primer coating composition, comprises a phosphorylated acrylic polymer, The coating provides excellent corrosion protection even without a conventional phosphate pretreatment.

A method for obtaining a cured multi-layer coating with good intercoat adhesion, comprising the steps of:

Method for a multilayer coating

The present invention relates to a thermoset powder coating composition and method of application. The coating includes a copolymer having a reactive functionality selected from the group consisting of epoxy, carboxy, and hydroxy functionalities and mixtures thereof, a suitable crosslinking agent capable of reaction with the reactive functionality on the copolymer, and an aliphatic or aromatic crystalline, hydroxyl containing compound having a melting point of between 30.degree. C. and 150.degree. C. and a flow control agent. The powder coating is a pigmented or clear coat powder composition applied over a primer layer.

Method for powder coatings

A thermosetting powder coating composition resistant to overspray incompatibility defects that comprises solid particulates of a uniform mixture of (a) a polyester resin having an average of two or more carboxyl groups, (b) a first crosslinker that is reactive toward the carboxyl groups of the polyester resin, (c) from 1% to 20% of a reactive acrylic copolymer having a weight average molecular weight of from 10,000 to 40,000, and (d) a second crosslinker that is reactive toward the reactive functionality of the acrylic copolymer is described.
