Electrodepositable coating compositions and their use in a method of cationic electrodeposition |
摘要 |
In accordance with the present invention, an electrodepositable composition and a method of electrodeposition using the composition are provided. The electrodepositable composition comprises (a) an active hydrogen-containing, cationic salt group-containing resin electrodepositable on a cathode; (b) a capped polyisocyanate curing agent; and optionally, (c) a metal-containing catalyst. The capped polyisocyanate curing agent comprises a polyisocyanate at least partially capped with a material having the structure: wherein n is a number of 1 to 10; m is a number of 1 to 10 and R is hydrogen or an alkyl or aryl group or substituted alkyl or aryl group having from about 1 to about 30 carbon atoms.
