The compositions may further include an organometallic catalyst.

Both of these inhibitory effects are reversed upon acid evaporation, which may substantially occur after the composition has been applied to a substrate. The delay in crosslinking achieved by use of the acid, however, may facilitate more complete evaporation of solvents from the coating, resulting in improved coating properties.
