Amino crosslinking agents functionalized with carbamate groups and coating compositions containing the same

摘要

A crosslinking agent comprising one or more carbamate groups or groups convertible to carbamate and two or more polyfunctional amino moieties having the formula ,wherein L is selected from the group consisting of alkyl or aryl, cycloalkyl and alkylaryl having a carbon chain length between 1 and 6 carbon atoms and N is a polyfunctional amino moiety. L may also have additional bridging groups such as eaters, ethers, ureas, or urethanes groups. Also included is a method of making the croselinker, a coating composition containing the crosslinker and a method for coating a substrate with the composition.
