PR-1776® Class C, Lightweight Fuel Tank Sealant
PR-1776 Class C sealant is a low density, aircraft integral fuel tank sealant with a service temperature range from -65°F (-54°C) to 250°F (121°C). The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels, (both jet fuel and aviation gas) and will resist limited contact to diphosphate ester based hydraulic fluids.

PR-1776 Class C sealant is a low density, high temperature aircraft integral fuel tank sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 360°F (182°C). This material is designed for brush sealing of fuel tanks and other aircraft fuselage sealing applications. It offers as much as a twenty percent weight savings, per unit volume, over traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels, (both jet fuel and aviation gas) and will resist limited contact to diphosphate ester based hydraulic fluids.
