Silane end-capped polyether (SCP / STP hybrid polymer), endcapped with a dimethoxy(methyl)silyl methyl group (alpha effect) on a polypropylene oxide backbone — a different silane termination from the trimethoxysilyl chemistry. 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, listed in the technical data below.
