Abstract:
Coating formulations especially useful for topcoat and clearcoat applications contains an isocyanate-reactive resin, a blocked isocyanate curative, and particles which bear blocked isocyanate functionalities, a considerable portion of which unblock at a temperature lower than the unblocking temperature of the curative. As a result, the coatings exhibit improved scratch resistance.
