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
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
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
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.
