Overview

PR-1425 Class B sealant is specifically formulated for fillet sealing of properly prepared glass, polycarbonate, acrylic, and other aircraft substrates without causing crazing. The uncured material is a low sag, thixotropic paste that can be easily applied using an extrusion gun or spatula. 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). The cured sealant exhibits excellent adhesion to common aircraft substrates and maintains its integrity under various environmental conditions. The storage life of PR-1425 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

  • Thermal rupture resistance allows it to retain pressure of 10 psi with negligible deformation.
  • Low temperature flexibility at -65°F (-54°C) ensures no cracking, checking, or loss of adhesion.
  • Corrosion resistance prevents corrosion, adhesion loss, softening, or blistering.
  • Flexibility is maintained with no cracks after bending 180 degrees over a 0.125 inch (3.18 mm) mandrel.
  • Repairability to itself is excellent for both freshly cured and fuel-aged or abraded fillets.
  • Resistance to other fluids includes excellent performance against water, alcohols, petroleum-based and synthetic lubricating oils, and petroleum-based hydraulic fluids.
  • Fungus resistance ensures non-nutrient properties to prevent fungal growth.
