Product Description

Silicone Structural Insulating Glass Sealant for secondary seal


Two part silicone sealant suited for the secondary sealing in structural insulating glass units




Two part, neutral fast cure rate, suitable for factory application.

High level of tensile strength and mechanical properties.

Excellent adhesion to a wide range of substrates including coated glass, low -E glass, tempered glass, laminated glass, aluminium and steel spacers etc.

Excellent weatherability and high resistance to ultra-violet radiation ,heat and humidity, and ozone.

Excellent resistance to temperature extremes, unaffected performance from –50 ℃ to +150 ℃.

Excellent unprimed adhesion to wide range of substrates.

Good compatibility with other neutral silicone sealants.




Part A (base) of GB 886 is available in white, part B(curing agent) in black, black colour after mixing.




GB 886 Silicone Structural Insulating Glass Sealant is specially designed for use as secondary sealant for structural insulating glass units.




These values are not intended for use in preparing specifications.

GB 886 is available in kit: part A base in 200L drums (net 190L), part B is available in 20L pails (net 19L).




GB 886 is designed to meet or even exceed the specification of Chinese national standard GB24266-2009.




GB 886 should be stored in original unopened containers. It has a shelf life of months from the date of manufacture.




GB 886 should not be applied:

For structural glazing of glass units onto a metal frame. GB 992 two part structural silicone and GB 999 one part structural silicone are recommended for that application.

To the materials that bleed oils , plasticizers or solvents, such as impregnated wood, oil-based caulks.

To frost laden or damp surfaces.

For continuous water immersion.

When surface temperature below 4℃ or over 50℃.
