GB1098 High Performance Silicone Weatherproofing Sealant is specially designed for:

Weather seal for the high-rise curtain walls and skyscrapers.

Weather seal for the large-sized metal and glass panel curtain walls, spider systems.

Weather seal of other construction joints with higher movement or with higher safety requirement.




GB 1098 is available in black, gray, white and other customized colours.




GB 1098 is designed to meet or even exceed the requirements of:

Chinese national specification.

GB/T 22083-2008 class 50.

GB 1098 is available in 350ml disposable cartridges (net 300ml),24 pieces to a carton and sausages (net 590ml),20 pieces to a carton.




GB1098 should be stored in original unopened containers. It has a shelf life of 12 months from the date of manufacture.




GB1098 should not be applied:

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

In totally confined spaces as sealant requires atmospheric moisture for cure.

To frost laden or damp surfaces.

For continuous water immersion.

When surface temperature below 4℃ or over 50℃.

To porous substrates such as stone, concrete before confirmation with manufacturer.




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.


Application Method

Install back-up materials or joint fillers, setting blocks, spacer shims, and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required for non-porous surfaces, but may be necessary for optimal seal performance of certain porous surfaces. So adhesion test is always recommended.


Apply GB 1098 in a continuous operation using dispensing guns. Before a skin forms, tool the sealant with light pressure to spread the sealant against the backing materials and joint surfaces. Remove masking tape as soon as the bead is tooled.




GB 1098 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.
