PRC Desoto - PR-1828 B1/2 Rapid Cure Fuel Tank Sealant - 6 oz
PR 1828 Class B is a rapid curing, primerless to most common substrates, aircraft integral fuel tank sealant. It has a service temperature range from -60 C to +150 C, with intermittent use to +215 C.
PR 1828 Class B has excellent low temperature curing characteristics. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas.
PR 1828 Class B is a two-part, chemically curing Permapol P-3 polythioether polymer based sealant characterized by a rapid cure at low temperature to a fuel resistance elastomer. This material has application temperature as low as +5 C and is unaffected by changes in relative humidity. The mixed compound is a thixotropic material, which can be readily applied by extrusion or injection gun.
