CLEARCOATING COMPOSITION WITH UNBLOCKED ACID CATALYST

摘要

A two-component solvent-borne clearcoat composition comprising an unblock ed acid catalyst, a film-forming binder, and an aminoplast crosslinking agen t (e.g., a melamine formaldehyde crosslinking agent) surprisingly provides e nhanced appearance when compared to a one-component clearcoating composition containing blocked acid catalyst cured at temperatures above 121°C (250°F).
