Application Limitations
Guibao 996 should not be applied
- As structural sealant.
- To the materials that will bleed oil, plasticizer or solvent, such as pregnated wood.
- To the places totally confined as sealant requires atmospheric moisture to cure.
- To damp or frost-laden surfaces.
- To places damp all the year round or in continuous immersion in water.
- When surface temperature is below 4 or over 40,recommendation is not recommended.
Safe-handling Information
Completely cured Guibao 996 is not toxic, but avoid contacting with eyes before it is cured. If that happens, rinse with a lot of water and seek medical treatment. Uncured Guibao 996 should be kept away from children. The product will give off low-molecule substance, so construction area and cure area should be kept well ventilated to avoid the unfavorable effect on human health caused by the over-concentration of low-molecule substance.
