PRC Desoto - PR-1773 B Access Door Sealant, Pint | PR1773B1-2PT
PR-1773 Class B is a low adhesion, non-chromate, corrosion inhibitive sealant. It has a service temperature range from -65┬░F (-54┬░C) to 250┬░F (121┬░C), with intermittent excursions up to 300┬░F (149┬░C). The material is designed for use as an access door sealant or in the fabrication of form-in-place (FIP) gaskets. This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals.
PR-1773 Class B is a two-part, manganese dioxide cured, 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 removable seal to common aircraft substrates.
