PPG FR80 (5-Ltr-Tin)

Additional Product Information

Overview

FR80 is a high-performance two-pack pigmented epoxy filler designed as a ground coat for aircraft external surfaces. It enhances the appearance and durability of epoxy or polyurethane topcoats while providing reliable adhesion to composite and metal substrates. FR80 is widely used in aviation MRO environments, offering teams a fast, dependable solution for surface preparation and finishing.
