Overview
P/S 895 Class B is an aerodynamic smoothing sealant. This material is designed for sealing aircraft structures and pressurized cabins or for depression filling and smoothing applications. The cured sealant maintains excellent elastomeric properties after prolonged exposure to both jet fuel and aviation gas. P/S 895 Class B is a two-part, manganese dioxide cured, polysulfide sealant. This sealant has excellent adhesion to common aircraft substrates.
Features & Benefits
Thermal rupture resistance, retaining pressure of 10 psi with negligible deformation before and after immersion in JRF
Low temperature flexibility at -65°F (-54°C) with no cracking, checking, or loss of adhesion
Corrosion resistance with no loss of adhesion or softening after immersion in salt water
Resistance to hydrocarbons with minimal weight loss after 7 days @ 140°F (60°C) immersed in JRF
Repairable to itself, excellent for both freshly cured and fuel-aged fillets
Outstanding resistance to water, alcohols, petroleum-based and synthetic lubricating oils, and petroleum-based hydraulic fluids
Fungus resistant and non-nutrient
