PRIMER: EPOXY,SURFACER,GL, SHERWIN-WILLIAMS P/N CM0560563 GA

Sherwin-Williams CM0560563 GA is a two-component epoxy surfacer primer engineered to provide a uniform, tightly bonded foundation on aluminum, composite, and treated steel aircraft substrates. Its dense, corrosion-inhibiting film fills surface imperfections and promotes optimal topcoat adhesion in demanding OEM and maintenance environments. The formulation withstands hydraulic fluids, fuel, de-icing chemicals, and temperature swings common in airframes and nacelles, while remaining compatible with polyurethane and epoxy topcoats. Applied by spray, it levels easily, cures to a hard, sandable finish, and supports long-term structural protection in both interior and exterior aerospace applications.
