GB1099 is designed to meet or even exceed the requirements of:
Chinese national specification GB16776-2005 Silicone Sealant for Structural Glazing.
Complies with ASTM C 1184.
GB1099 should be stored at or below 27℃ in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
GB1099 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℃


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 1099 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 1099 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.
