EdgeSil IGS3703E sealant is a single-component silicone designed for secondary sealing in insulating glass (IG) systems.

EdgeSil IGS3703E sealant is a neutral-cure, moisture-activated silicone sealant engineered for use as the edge seal in insulating glass units. Formulated to meet EN1279-4 requirements, it combines excellent pumpability, minimal slump, and strong bond performance on coated and uncoated glass, aluminum, and steel spacers.

Its low odor, high tooling rate, and compatibility with other silicone sealants make it a smart, high-performing choice for insulating glass production.
