PPG CA8800-I01050 (5-Ltr-Tin)

Additional Product Information

Overview

Desothane HS CA8800 Buffable Polyurethane Topcoats are high-solids aerospace polyurethane finishes designed to protect aircraft exteriors when applied over approved epoxy primers and surfacers. Widely used across aviation manufacturing and MRO environments, this coating delivers exceptional gloss retention, chemical resistance, and long-term durability. Aircraft finishing teams rely on this system for its buffable surface, flexible application, and ability to maintain appearance and performance in harsh operational environments.
