Factory Supply Hot Melt Butyl Sealant for Insulating Glass First Sealing

​​Hot Melt Butyl Sealant​​ is a high-performance sealing material based on butyl rubber or polyisobutene, specifically designed for the primary seal of insulating glass. Its key advantages include:

1. ​​Superior Sealing Performance​​: Extremely low moisture vapor transmission rate (≤1.1g/m²·d), effectively blocking humidity to prevent condensation and oxidation in insulating glass.
2. ​​Strong Adhesion​​: Bonds firmly to substrates like glass and aluminum alloy, with shear strength ≥0.2MPa, ensuring structural stability.
3. ​​Durability & Weather Resistance​​: Maintains plasticity in extreme temperatures (-40°C to 90°C or even -50°C to high heat), resists UV aging, and offers a service life exceeding 20 years.
4. ​​Eco-Friendly & Efficient​​: Solvent-free, non-toxic, and cures instantly upon cooling after heating (110–140°C), eliminating curing time and boosting production efficiency.
5. ​​Wide Applications​​: Compatible with photovoltaic modules, automotive sealing, and more, making it a critical material for sealing systems.

With these features, hot melt butyl sealant is the preferred sealing solution for industries like construction and renewable energy.
