PRC Desoto – PR-1828 B1/4 Rapid Cure Fuel Tank Sealant – 6 oz | PR1828B1-4

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.

To use this fuel tank sealant, first make sure the surface is clean and dry. For most common substrates, you don’t need a primer. Mix the two parts as per the instructions. The application temperature should be at least +5 C. You can apply it easily with an extrusion or injection gun since the mixed compound is thixotropic. Make sure to follow the recommended temperature range of -60 C to +150 C, and for intermittent use up to +215 C. After application, let it cure properly. Keep it away from extreme humidity changes as it’s not affected by normal relative humidity changes. Also, ensure proper storage to maintain its effectiveness.
