Overview
PR-1422 Class B sealant is specifically formulated for fillet sealing of fuel tanks and other aircraft fuselage sealing applications. It maintains excellent performance after prolonged exposure to fuels, with a service temperature range from -65°F (-54°C) to 250°F (121°C), and can withstand intermittent excursions up to 275°F (135°C). The uncured material is a low sag, thixotropic paste that can be easily applied using an extrusion gun or spatula. Once cured at room temperature, it forms a resilient sealant with excellent adhesion to common aircraft substrates. The storage life of PR-1422 Class B is at least 9 months when stored in original, unopened containers at temperatures between 40°F (5°C) and 80°F (27°C).
Features & Benefits
The thermal rupture resistance allows it to retain pressure of 10 psi with negligible deformation.
It exhibits low temperature flexibility, showing no cracking, checking, or loss of adhesion at -65°F (-54°C).
The sealant has excellent corrosion resistance, with no corrosion, adhesion loss, softening, or blistering.
It demonstrates strong resistance to hydrocarbons, enhancing durability.
The resilient finish prevents the collection of dirt and debris in the blades.
It allows for increased water-washing intervals for gas turbine compressors.
The sealant is highly reliable in harsh environmental conditions.
It has non-nutrient properties that prevent fungal growth.
