Description
PR-1770 is a two-part, high strength/temperature resistant, brushing sealant for use over a temperature range of -55°C to +180°C, with outstanding resistance to aircraft fuels and lubricating oils and resistance to degradation by phosphate ester type hydraulic oils.
PR1770A
PR-1770A is a manganese dioxide cured sealant based on Permapol® P-5 liquid polymers, a chemically modified, improved class of polysulphide polymers covered by US Patent 4,623,711. The uncured material is a thick liquid suitable for application by brush or roller. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels.
PR1770B
PR-1770 Class B is a two-part, manganese dioxide cured Permapol® P-5 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.
PR1770C
PR-1770C is a manganese dioxide cured sealant based on Permapol® P-5 liquid polymers, a chemically modified, improved class of polysulphide polymers covered by US Patent 4,623,711. The uncured sealant is a thick liquid suitable for application by brush or roller. The cured sealant maintains excellent elastomeric properties after prolonged exposure to aircraft fuels.
