Additional Product Information
Overview
PPG PR1776MB2?B1001 is a high?performance, two?component sealant designed for weight?critical aircraft structures where excellent fuel resistance and flexibility are essential. It reduces weight by up to 20% per unit volume compared to traditional sealants while maintaining superior adhesion to aluminium, titanium, and primed surfaces.
Key Technical Specs
Reduces weight up to 20% per volume vs traditional sealants without compromising fuel resistance or flexibility. Superior adhesion with low?sag thixotropic paste suitable for extrusion or spatula application.
Typical Applications
Designed for integral fuel tank and fuselage sealing in weight?critical aerospace structures. Suitable for both OEM and MRO environments.
Surface Preparation
Clean substrates with approved solvents using lint?free wipes to remove grease, oils, and residues. Surfaces should be progressively cleaned and dried prior to application to prevent redeposition. Adhesion testing is recommended for new substrates.
Packing & Mixing
Available in two?part Semkit packages, two?part can kits, or pre?mixed frozen cartridges. Mix Parts A and B separately, then combine and blend thoroughly, scraping container sides and bottom. Apply promptly after mixing.
Storage Life
Semkit and can kits: minimum 9 months at 40 80 F (4.5 27 C). Pre?mixed frozen cartridges: 28 days at ?40 F (?40 C).
Performance Highlights
Specific gravity: 1.29; nonvolatile content: 94%; ultimate hardness: 50 Shore A; tensile strength: 263 psi; elongation: 366%. Fuel immersion tensile strength: 269 psi; elongation: 439%. Low?temperature flexibility: no cracking at ?65 F (?54 C). Weight loss (7?day JRF @ 140 F): 4.7%. Fungus resistance: non?nutrient.
