Two part, neutral fast curing 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, aluminum 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 ℃.

Good compatibility with other neutral silicone sealants.




Part A (base) of GB 882 is available in white, part B (curing agent) in black, black color after mixing.




GB 882 Silicone Insulating Glass Sealant is specially designed for use as secondary sealant for insulating glass units.



GB 882 is available in kit: part A in 200L drums (net 180L), part B in 20L pails (net 18L).




GB 882 is designed to meet or even exceed the requirements of:

Chinese national specification.

GB/T 29755-2013.




GB 882 should be stored in original unopened containers. It has a shelf life of 12 months from the date of manufacture.




GB 882 should not be applied:

For structural glazing.

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℃.




Surface Preparation

Clean all joints removing all foreign matter and contaminants such as oil, grease, dust, water, frost, old sealants, surface dirt, or glazing compounds and protective coatings.


Mixing and Dispensing

To obtain the optimal performance of GB 882, it is recommended that base and curing agent thoroughly mixed using a two-part silicone dispensing machine.

GB 882 should be mixed at a ratio of 9:1~11:1 base to curing agent by volume, or 11:1~13:1 base to curing agent by weight for optimal performance.

Lot matching of GB 882 base to curing agent is not required. Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.

GB 882 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.





GB 882 is a chemical product, not edible, no implantation into body and should be kept away from children.

Cured silicone rubber can be handled without any risk to health.

Should uncured silicone sealant contact with eyes, rinse thoroughly with water and seek medical treatment if irritation persists.

Avoid prolonged exposure of skin to uncured silicone sealant.

Good ventilation is necessary for work and cure places.
