Overview

This sealant contains no organic solvents and does not craze substrates. The cured material exhibits excellent resistance to UV and weather exposure. 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. 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 sealant has excellent adhesion to common aircraft substrates. The B-1/2 classification indicates an application life of 1/2 hour. The storage life of PR-1829 Class B is at least 9 months when stored at temperatures below 80°F (27°C) in original, unopened containers.
