Description
PR-706 is a non-curing fuel tank channel sealant. It has a service temperature range from -65°F (-54°C) to 220°F (104°C). This material is designed for sealing aircraft fuel tanks utilizing a channel/groove design with 5 to 15 mils wide gaps. The material offers excellent resistance to water and hydrocarbon aircraft fuels like JP-4 and JP-8.
PR-706 is one part polysulfide compound. The material is a heavy, putty-like compound suitable for high-pressure injection gun application. The following tests follow MIL-S-85334 (AS) specification test methods.
Surface Preparation
PR-706 exhibits positive adhesion to most metal and coated metal surfaces. Therefore, substrates should be cleaned with solvents to remove contamination such as dirt, grease, or other processing lubricants.
Application
PR-706 is supplied in 6 oz. Semco® cartridges. Maximum pressure of 2800 lbs (12,455 Newtons) is used at an air pressure of approximately 40 psi (276 K-Pa) using a model 223 Grover-Smith injection gun with a Semco® cartridge adapter kit #226358. This material is compatible with polyfluoro and polycyanosiloxane-based channel sealants and polysulfides.
