PR-1829 Class B is a rapid aircraft windshield and canopy sealant. It 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 B 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.
These sunglasses were a gift to our grandson. He is a fairly new pilot and wanted these sunglasses as a birthday gift. He is very happy with them.
The staff at Pilots HQ were great to deal with and managed pto get the sunglasses to me just in time for our grandson’s birthday.
Thanks for the help.
Heard about Boelube for years. Finally had a chance to try it on several projects. It definitely works well and better than anything else I have ever tried. Would recommend.
