FEATURES
Two parts , neutral cure to form an extremely tough elastomeric rubber ensuring a durable, flexible, and watertight bond.
Non-corrosive to metals, coated glass, low-E glass and many other substrates.
Excellent weatherability and high resistance to UV radiation ,heat and humidity, and ozone.
Excellent stability through wide temperature range from –50 ℃ to +150 ℃.
High level of mechanical properties.
Good compatibility with other neutral silicone sealants.
PACKAGING
GB 992 is available in kit: part A in 200L drums (net 190L), part B in 20L pails (net 19L).
SPECIFICATIONS
GB 992 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.
STORAGE AND SHELF LIFE
It has a shelf life of 12 months from the date of manufacture.
LIMITATIONS
GB 992 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℃.
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.
Mixing and Dispensing
To obtain the optimal performance of GB 992, it is recommended that base and curing agent thoroughly mixed using an airless two-part silicone dispensing machine.
GB 992 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.
Lot matching of GB 992 base to curing agent is not required. Before use, it is recommended that curing agent be fully stirred to ensure the homogeneity of all components.
GB992 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.
Priming
Priming is not usually required when using GB 992. But it is essential that adhesion is tested prior to use to decide whether to use primer or not.
Masking and Tooling
Areas adjacent to joint may be masked to ensure a neat sealant line. Do not allow mask tape to touch clean surfaces to which the silicone sealant is to adhere. Tooling should be completed in one continuous stroke after sealant application. Masking tape should be removed immediately after tooling.
Equipment Cleaning
When not being used, it is recommended that the dispensing equipment be purged either with the base component or flush with suitable solvent.
SAFETY INFORMATION
GB 992 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 needed for work and cure places.
