PR 1826 Class B Aluminum Grey Quick Repair Sealant

PR 1826 B is a thixotropic aluminum colored compound for use on the exterior of aircraft to provide aerodynamic smoothness, to seal against weather, and prevent faying surface corrosion from chemical cleaners and fuel spillage.

PR 1826 B is a rapid curing sealant designed for use at temperature between -60° C to +150° C, with intermittent use to +215° C.

PR 1826 Class B is a two-part, chemically curing Permapol P-3 polythioether polymer based sealant characterized by a rapid cure at low temperature. This material has application temperature as low as +5° C.
When used with primer PR 1826 Adhesion Promoter, the sealant adheres to alclad, titanium, stainless steel, coated surfaces and sealant.

PR 1826 Adhesion Promoter will promote adhesion of PR 1826 Class B to itself and to materials and treatments commonly used for aircraft fasteners.  The mixed compound is a thixotropic material which can be readily applied by extrusion or injection gun.
