Pro-Seal 870 Corrosion Inhibitive Sealant

Discription:

P/S 870 is a corrosion inhibitive two-part, manganese dioxide cured polysulfide sealant. It has a service temperature range from -65°F (-54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C). This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals. The cured sealant maintains elastomeric properties after limited exposure to both jet fuel and aviation gas.
