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
FEATURES:
- One part, neutral cure to form an
extremely tough elastomeric rubber
ensuring a durable, flexible, and
watertight bond
- Non-corrosive to glass, metal 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
LIMITATIONS
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
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 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.
SAFETY INFORMATION
- 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.
