PPG Aerospace® P/S 870 A-2 Gray MIL-PRF-81733D Type I-2, Class 1, GA Spec Corrosion Inhibitive Sealant - Pint Kit

P/S 870 Class A is a corrosion-inhibiting sealant. Its service temperature range is -54°C (-65°F) to 121°C (250°F), with intermittent variations up to 135°C (275°F). This material acts as an effective barrier against common causes of corrosion in aluminum alloys or between dissimilar metals. The cured sealant retains its elastomeric properties after limited exposure to both jet fuel and aviation gas.

P/S 870 Class A is a two-component polysulfide compound cured with manganese dioxide. The uncured material can be brush-applied in thicknesses up to 25 mils. It cures at room temperature to form a tough sealant with excellent adhesion to common aircraft substrates.

The following tests are in accordance with the test methods of specification MIL-PRF-81733 Type I.
