The AMS 3333 specification covers a two-part polysulfide sealing compound specifically designed for aircraft windshields, canopies, and transparencies. Its primary purpose is to provide a flexible, weather-resistant seal between transparent panels (glass, acrylic, or polycarbonate) and their frames, operating at temperatures up to 250°F (121°C). Key features include excellent UV resistance, a typically black color for aesthetic finishing, and a formulation optimized to prevent crazing or damage to sensitive plastic substrates.
