Momentive Performance Materials GE Silicones IGS3767 Two-Component Insulating Glass Silicone
Categories: Polymer; Thermoset; Silicone

Material Notes: IGS3767 adhesive silicone is an optimized, high-modulus, neutral curing sealant for edge seal applications for gas and air filled structural and non- structural insulating glass units. IGS3767 two-component silicone offers variable work life with fast deep section cure to accommodate scheduling and production needs.

Features: High Modulus, High Elastic Recovery, Fast Cure, Compatibility, Non-flammable.

Applications: Structural Glazing, Silicone Durability, Adhesive. Note: IGS3767 silicone should only be used in the fabrication of insulating glass where the dual seal method of fabrication is used. The moisture vapor transmission rate of silicone sealants is sufficiently high as to preclude their use in the fabrication of single seal insulating glass units. Silicone setting blocks are recommended for direct contact with IGS3767 silicone. Avoid using non-silicone materials (i.e., EPDM, Neoprene) as they could degrade or discolor the secondary seal over time. Avoid IGS3767 to be in contact with or exposed to sealants that evolve acetic acid cure byproduct. Not recommended for water immersion applications.

IGS3763 is the black equivalent.
