GE SWS weatherproofing sealant is a single-component, neutral cure silicone, which is excellent for use in new or remedial weathersealing applications. GE SWS exhibits negligible change in physical properties after weathering and upon cure, becomes a low-modulus, formed-in-place durable rubber building joint and glazing sealant. GE SWS rubber sealant, when cured, exhibits excellent long-term resistance to natural weathering, including: ultraviolet radiation, high and low temperatures and rain and snow, with little change in elasticity. SWS offers the durability of a true silicone sealant but at an economical price level similar to lesser-performing sealant types. GE SCS has a ±50% movement capacity, can accommodate 50% movement in both extension and compression and has excellent recovery after cycling. GE SWS adheres to many substrates and finishes without requiring a primer. GE SWS may be considered for use with the following materials: glass, polycarbonate, vinyl, plastics, wood, painted & anodized aluminum, brick, terra-cotta, ceramic and porcelain materials, concrete and natural stones. Some finishes or substrates may require a primer. GE SWS has good workability being a temperature-stable paste which is easily applied and tooled under hot or cold weather conditions. GE SWS also allows sufficient skinning time for sealant placement and tooling.
