For metal coated glass glazing.
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.
Mask areas adjacent to joints to ensure neat sealant lines. Primer
is generally not required for non-porous surfaces, but may be
necessary for optimal seal performance of certain porous surfaces.
So adhesion testing is always recommended.
Apply GB 995 in a continuous operation using dispensing guns.
Before a skin forms, tool the sealant with light pressure to spread
the sealant against the backing materials and joint surfaces.
Remove masking tape as soon as the bead is tooled.
GB 995 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 periods of exposure of skin to uncured silicone
Good ventilation is necessary for work and cure places.
