PR-2201 electrically conductive non-chromated corrosion inhibitive sealant

PR-2201 Class B is an electrically conductive, rapid cure, corrosion inhibitive sealant. It has a service temperature range from -67°F (-55°C) to 250°F (1 21 °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 prolonged exposure to both jet fuel and aviation gas.
