GB 882 is available in kit: part A in 200L drums (net 180L), part B in 20L pails (net 18L).
GB 882 is designed to meet or even exceed the requirements of:
Chinese national specification.
STORAGE AND SHELF LIFE
GB 882 should be stored in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
GB 882 should not be applied:
For structural glazing.
To the materials that bleed oils , plasticizers or solvents, such as impregnated wood, oil-based caulks.
To frost laden or damp surfaces.
For continuous water immersion.
When 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.
Mixing and Dispensing
To obtain the optimal performance of GB 882, it is recommended that base and curing agent thoroughly mixed using a two-part silicone dispensing machine.
GB 882 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 for optimal performance.
Lot matching of GB 882 base to curing agent is not required. Before use, it is recommended that curing agent be stirred to ensure the homogeneity of all components.
GB 882 part B curing agent will react with atmospheric moisture, therefore should not be exposed to air for prolonged periods of time.
Priming is not usually required when using GB 882. 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 joints 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.
When not being used, it is recommended that the dispensing equipment be purged either with the base component or flush with suitable solvent.
GB 882 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.
