Momentive Performance Materials GE Silicones SWS Single-component, neutral cure silicone
Categories: Polymer; Thermoset; Silicone

Material Notes: 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. As a general purpose sealant for seams and curtainwall frames, screw heads, back pans, etc. SWS is not: For use in structural glazing applications. For use in food contact applications. For use in applications where the product will be in continuous contact with water. Paintable (except when using SilShield* 2400 or Optic* 2401 silicone elastomeric coating). For use on wet, damp, frozen or contaminated surfaces.
