GUIBAO 997 should not be applied:

As structural sealant

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 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, surface dirt, protective coatings.


Application Method

Install back-up materials or joint fillers, setting blocks, spacer shims, and tapes. 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 test is always recommended.


Apply GUIBAO 997 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.




GUIBAO 997 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.
