PPG 1829 Class B1/4 Rapid Curing Windshield Canopy Sealant has a service temperature range from -80°F (-62°C) to 320°F to (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 B1/4 is a two-part, epoxy cured Permapol® 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.
Available in a 6oz quantity.
