Product Details

PPG PR-1764 Class B sealant is an electrically conductive, corrosion inhibitive sealant. It has a service temperature range from -67°F (-55°C) to 250°F (121°C), with intermittent excursions up to 360°F (182°C).

The cured sealant maintains electrical continuity in aircraft applications. This material provides excellent long-term EMI/RMI protection. The product is also corrosion inhibitive and protects against the common causes of corrosion on aluminum alloys or between dissimilar metals. The cured sealant is resistant to prolonged exposure to both jet fuel and aviation gas.

PPG PR-1764 Class B is a two-part, nickel filled, manganese dioxide cured, Permapol® P-3 polythioether compound. The uncured material is a low sag, thixotropic paste suitable for application by extrusion gun or spatula. This sealant has excellent adhesion to common aircraft substrates when correctly primed with PPG PR-148® Adhesion Promoter.
