PPG PRC DeSoto - Brown BMS Type II, Class B-2 Spec Low Weight Fuselage Sealant | PR1776MB2-60Z

This 6 oz SemKit of PPG Aerospace PRC-Desoto PR-1772 Class B is a low weight fuselage sealant with a 2 hour application life. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). It offers as much as a thirty percent weight savings, per unit volume, over traditional sealants used for these purposes. The cured sealant maintains excellent elastomeric properties after limited exposure to both jet fuel and aviation gas.

PR-1772 Class B is a two part, chemically curing polysulfide compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
