US Classification:

524555

Abstract:

A low temperature cure, two component coating composition having an improved balance between pot life and speed of cure is provided. The coating composition includes a crosslinkable, solvent borne, solution polymer containing certain activated ester groups, and a hemiaminal. Also provided is a crosslinked coating obtained by curing the composition. Additionally, there is provided a process for increasing the pot life of a low temperature cure coating composition. The process includes the step of forming a hemiaminal from a crosslinking agent preferably prior to mixing the crosslinking agent with the polymer.
