Product Properties


Product Information

PR-1776 Class C 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 application.

It offers aircraft fuselage sealing applications. It offers as much as twenty percent weight savings, per unit volume, over traditions 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.

PPG PR-1776 Class C is a two-part, manganese dioxide cured Permapol° P-5 modified polysulfide. The uncured material is a roller grade liquid suitable for application by brush or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
