IQ Structural Glazing Sealant — IQC-GL82
SKU: Two-component high-modulus structural silicone · IQC-GL82
True structural-grade silicone for curtain wall and insulating glass assembly.
About
IQC-GL82 is a two-component, high-modulus structural silicone sealant engineered for genuine load-bearing glazing work — the structural adhesion and sealing of large-scale and high-rise glass curtain walls, workshop-assembled curtain wall panels, and the structural bonding of insulating glass units (double glazing). It offers excellent resistance to temperature extremes, ozone and UV, with strong adhesion and elasticity across common building materials. Components are mixed at a 10:1 ratio (A:B), with the ratio adjustable to fine-tune cure speed.
Key Features
- Genuine structural-grade sealant — rated for load-bearing glazing applications
- High modulus for structural strength in large glazing assemblies
- Excellent resistance to temperature extremes, ozone and UV
- Two-component system — adjustable mix ratio to tune cure speed
- Strong adhesion and elasticity across common building substrates
Typical Applications
- Structural adhesion and sealing of large-scale and high-rise glass curtain walls
- Workshop-assembled curtain wall panels (glass and metal components)
- Structural bonding and sealing of insulating glass units (IGU / double glazing)
