| SWS weatherproofing sealant is a single-component, neutral cure silicone, which is an excellent candidate for use in new or remedial weathersealing applications. SWS exhibits negligible change in physical properties after weathering and upon cure, becomes a low-modulus, formed-in-place durable rubber building joint & glazing sealant. Features: Silicone Durability, High Performance, ±50% Movement Capacity, Primerless Adhesion. SWS is an excellent candidate to consider: As a weatherproofing material when sealing between dissimilar or similar materials in either new or remedial glazing and sealing applications, window perimeters and punched openings. For sealing to precast concrete, site cast concrete and tilt-up concrete joints.
