Silane end-capped polyether (SCP / STP hybrid polymer), terminated with a trimethoxysilyl group on a polyoxypropylene backbone. Isocyanate-free, cures via atmospheric moisture, paintable after cure, resistant to UV and weathering, and, compared with silicone sealants, resists staining and picks up less dirt. The grades in this chemistry are distinguished by viscosity and activity, listed in the technical data below.
