GB 999 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.
As exposed to air, GB 999 begins to cure inward from surface. Its tack free time is about 60 minutes, the full and optimal adhesion forms in about 21 days.
It has a shelf life of 12 months from the date of manufacture.
GB 999 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 substrate surface temperature below 4℃ or over 50℃.
HOW TO USE
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.
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 999 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 999 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.
