HOW TO USE
Mix part A base to Part B curing agent at a ratio of 6:1 by weight or 4:1 by volume, and then pot the mixture into the parts of substrates where needed, place at room temperature for initial curing for about 2～4 hours before conducting the next procedure. If precipitation occurs in Part A, just stir it well before use, and this does not affect the performance of the sealant.
When using automatic dispensing machine, set at a ratio of 6:1 by weight or 4:1 by volume of part A to Part B for a test first and then put into use.
STORAGE AND SHELF LIFE
GB4808 should be stored in original unopened containers and in cool and dry places, and be kept away from rain or direct sunshine.
GB 4808 has a shelf life of 6 months from the date of manufacture.
GB 4808 is non-hazardous for transportation.
Screw tight the cover of Part B immediately after use to avoid the exposure to atmospheric moisture
Part A base and part B curing agent should be fully mixed to ensure the homogenity of the sealant, or it affects the performance of the sealant.
Part A and Part B should be kept separately and get mixed on site, and be used within a short time after mixing.
For common low-voltage electrical potting, de-bubbling is not needed, but vacuum de-bubbling for 3～5 minutes is required for high voltage electrical potting.
GUIBAO 4808 is a chemical product, not edible, no implantation into body and should be kept away from children.
Should uncured silicone sealant contact with eyes, rinse thoroughly with water and seek medical treatment if irritation persists.
Avoid prolonged periods of exposure of skin to uncured silicone sealant.
Good ventilation is necessary for work and cure places.
