SEALANT: 654 SEMKIT | Flamemaster Chemseal

PR-1435 is packaged in a Semkit, which is a complete plastic cartridge assembly that stores, mixes, and applies multiple component adhesives, sealants, encapsulants, and other materials. Because PR14-35 is a two-part (A & B) sealant, the Semkit is ideal for this purpose.PR-1435 is a quick repair, aircraft integral fuel tank sealant. It has a service temperature range from -650F (-540C) to 2500F (1210C), with intermittent excursions up to 2750F (1350C). This material is designed for sealing of fuel tanks and other aircraft fuselage sealing applications. The cured sealant maintains elastomeric properties after exposure to both jet fuel and aviation gas.PR-1435 is a two part, dichromate cured polysulfide compound. The uncured material is suitable for application by extrusion gun or brush. It has excellent adhesion to common aircraft substrates when correctly primed with PR-148 Adhesion Promoter. The following tests are in accordance with AMS-S-83318 Class A specification test methods.
