PR-1829 Class B is a rapid aircraft windshield and canopy sealant. 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® polythioether compound. Unlike standard polysulfide windshield sealants, it can cure at low-temperatures and is unaffected by changes in relative humidity.
