GB1092 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.
GB1092 should be stored in original unopened containers. It has a shelf life of 12 months from the date of manufacture.
GB1092 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℃.
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 1092, it is recommended that base and curing agent thoroughly mixed using an airless two-part silicone dispensing machine.
GB 1092 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 GB1092 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.
GB 1092 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 1092.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.
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.
GB 1092 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.
