The present invention provides a composition of matter having the structure:where Q is a multi-valent organic moiety containing isocyanurate functionality; X is H, &#x2014;CHOH, or &#x2014;CHOR'; R&#x2032; is an alkyl or aryl group having from 1 to 12 carbon atoms; and y is at least 2. Also provided is a curable composition containing the composition of matter.

Etherified carbamate crosslinking agents and their use in curable compositions, particularly film-forming compositions

A reaction product is useful as a crosslinking agent for polymers having functional groups reactive with the reaction product such as hydroxyl, carboxylic acid, amide, thiol, urea, carbamate and/or thiocarbamate groups, wherein the polymer includes an acrylic, polyester, polyether and/or polyurethane. The reaction product is derived from a) a polyisocyanate or polyisocyanurate, b) a hydroxyalkyl carbamate, c) an aldehyde and d) at least one monohydric alcohol.

Etherified carbamate crosslinking agents and their use in curable compositions particularly film-forming compositions

A weldable curable coating composition with improved intercoat adhesion is disclosed comprising a resinous binder comprising a polymer (A) with functional groups and a crosslinking agent with functional groups reactive with those of polymer (A); an electroconductive pigment; and an adhesion promoting compound comprising boron containing compounds. In an alternative embodiment, the adhesion promoting compound may comprise siloxane polymer reacted with aluminates, titanates, zirconates, silicates, siloxanes, silanes, and mixtures thereof, wherein each component is different.
