Corrosion Inhibitive Sealants

PR-2870 Sprayable Non-Chromate Corrosion Inhibitive Sealant

PR-2870 Sprayable is a corrosion inhibitive sealant and elastomeric coating. It has a service temperature range from -80°F (-62°C) to 250°F (121°C), with intermittent excursions up to 300°F (149°C). This material acts as an effective barrier against the common causes of corrosion on aluminum alloys or between dissimilar metals.
PR-2870 Sprayable is a two-part, epoxy cured polythioether compound. The uncured material is suitable for application by spray. It cures at room temperature to form a resilient sealant having excellent adhesion to common aircraft substrates.
