PR-1764 M Class B is an electrically conductive, corrosion inhibitive, chromate and aromatic-free sealant. It has a service temperature range from -42°C (-43.6°F) to 130°C (266°F). The cured sealant maintains electrical continuity in aircraft applications. The product is also corrosion inhibitive and protects against the common causes of corrosion on aluminium alloys or between dissimilar metals. The cured sealant is resistant to prolonged exposure to both jet fuel and aviation gas. PR-1764 M Class B is a two-part, manganese dioxide cured, liquid polysulfide compound. The mixed compound is a low-sag, thixotropic paste suitable for application by extrusion gun or spatula. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates without shrinkage.
