Thicker formula resists sagging in vertical applications, yet still allows quick wet-outs of light to medium weight fabrics. MAS Epoxies FLAG Epoxy Resin is a medium body resin designed to perform as an adhesive and structural laminating foundation. Applications include filleting, fairing, laminating, gluing, barrier coating and cold molding. The medium viscosity allows for an easy incorporation of fillers when fairing putties, gluing slurries and filleting compounds are required. FLAG is more reactive than MAS Low Viscosity Resin when mixed with Medium Hardener, which keeps fillets and fairing from slumping. FLAG Resin is next day sandable when cured with Medium hardener at temperatures above 60F. FLAG Resin may be used with all MAS Hardeners, however, for filled applications we recommend Medium Hardener.
