Momentive Performance Materials GE Silicones SCS2350 Neutral cure silicone sealant
Categories: Polymer; Thermoset; Silicone

Material Notes: SCS2350 is a neutral cure silicone sealant that is an excellent candidate for general glazing and sealing as well as for internal frame sealing on curtainwall assemblies. SCS2350 is supplied as a paste and upon cure produces a durable silicone rubber seal.

Features: Silicone Durability, ±25% Movement Capacity, Faster Curing, Low VOC. SCS2350 is an excellent candidate to consider: As a weatherproofing material when sealing between dissimilar or similar materials in either new or remedial glazing / sealing applications. As an internal frame sealant for curtainwall assembly. As an adhesive in panel stiffener applications. SCS2350 silicone elastomeric sealant should not be used: Underwater or when in continuous contact with water. Where painting is necessary. When paintability is desired, consider SCS7000. As the structural sealant in Structural Silicone Glazing (SSG) applications. On mirrors. On wet, damp, frozen or contaminated surfaces.
