Edgetherm® 3500 Insulating Glass Butyl Sealant

Versatile hot melt butyl sealant engineered to improve insulating glass fabrication efficiency, moisture resistance, and long-term IG unit durability.

Edgetherm® 3500 is a versatile single-part insulating glass butyl sealant engineered to help IGU manufacturers improve fabrication efficiency while supporting long-term unit durability and thermal performance.

Designed for both manual and automated insulating glass production environments, Edgetherm 3500 sets quickly from its molten state, allowing insulating glass units to move rapidly through production and be glazed the same day. Its balanced performance characteristics help manufacturers maintain cleaner applications, minimize downtime, and improve overall process consistency.

Engineered for strong movement accommodation, low-temperature flexibility, and low moisture vapor transmission, Edgetherm 3500 functions as an effective moisture and gas barrier sealant for demanding insulating glass applications. The sealant is formulated to resist slumping and stringing during application while maintaining durable adhesion and flexibility throughout the life of the unit.

Compatible with a wide range of insulating glass manufacturing systems and warm-edge spacer technologies, Edgetherm 3500 supports efficient fabrication without sacrificing long-term insulating glass performance or seal integrity.
