PR-2200 Class B is an electrically conductive, rapid cure, corrosion inhibitive sealant. It has a service tem-perature range from -67°F (-55°C) to 250°F (121°C), with intermittent excursions up to 360°F (182°C). The cured sealant provides excellent electrical conductivity and EMI/RFI shielding effectiveness. This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. The cured sealant is resistant to exposure to both jet fuel and aviation gas. PR-2200 Class B is a two part, nickel filled, epoxy cured, Permapol® P-3.1 polythioether compound. The uncured material is a low sag, thixotropic paste suit-able for application by extrusion gun or spatula. This sealant has excellent adhesion to common aircraft substrates when correctly primed with PR-182 Adhesion Promoter. The following tests are in accordance with Boeing St. Louis MMS-327 specification test methods.
