PR1829 Rapid Cure Windshield & Canopy Sealant

PR-1829 Class B is a rapid curing aircraft windshield and canopy sealant.  It has a service temperature range from -80°F (-62°C) to 320°F (160°C), with intermittent excursions up to 420°F (216°C). This material is designed for fillet sealing of glass, polycarbonate, acrylic and other aircraft sealing applications. The product contains no organic solvents and does not craze substrates. The cured sealant exhibits excellent resistance to UV and weather exposure. PR-1829 Class B is a two-part, epoxy cured Permapol® P-3 polythioether compound. The uncured material is a low sag, thixotropic paste, suitable for application by extrusion gun or spatula. Unlike standard polysulfide windshield sealants, it can cure at low temperatures and is unaffected by changes in relative humidity.  This sealant has excellent adhesion to common aircraft substrates.

  • The product contains no organic solvents and does not craze substrates.
