PR-1770A is a dual-component, high temperature resistant sealant designed for brushing applications, functioning reliably across a wide temperature span from -55°C to +180°C. It boasts exceptional resilience against aircraft fuels, lubricating oils, and phosphate ester hydraulic oils, resisting degradation effectively. In its uncured state, the sealant presents as a viscous liquid, facilitating easy application by brush or roller. Once cured, it maintains superior elastomeric properties, even after prolonged exposure to aircraft fuels, ensuring enduring effectiveness. View our Class A products below.
PR-1770 Class B stands as a robust aircraft integral fuel tank sealant, boasting high strength and reliability. Tailored for fillet sealing within fuel tanks and other fuselage sealing applications in aircraft, this material maintains its exceptional elastomeric properties even after enduring prolonged exposure to both jet fuel and aviation gas.
Comprising a two-part formulation, Class B utilises manganese dioxide curing with Permapol P-5 polysulfide compound. In its uncured state, it presents as a low-sag, thixotropic paste, ideal for application using extrusion guns or spatulas. Upon curing at room temperature, it transforms into a resilient sealant, exhibiting excellent adhesion to commonly used aircraft substrates.
PR-1770C stands as a dual-component, high-temperature-resistant sealant, crafted for faying surface applications. It exhibits remarkable resilience against aircraft fuels, lubricating oils, and is adept at withstanding the degrading effects of phosphate ester hydraulic oils. In its uncured state, the sealant presents as a dense liquid, well-suited for application by brush or roller. Upon curing at room temperature, it transforms into a resilient sealant.
