Application

Weather-proofing and caulking sealing for hanging stone curtain walls and cement slabs

Bonding and sealing of stones to other substrates such as glass or metal

Caulking sealing for ceramic

 

 

Method of Use

First, you shall ensure that the substrates to be treated are clean and dry, with rust, dust and oil removed. You shall choose solvent for cleaning if necessary, dry before use.

Second, you shall paste protective material on the protected area, but do not touch surface to be treated

Third, you shall apply sealant to surface to be treated using an application gun

Forth, rework before curing, to ensure a smooth and beautiful appearance

 

Packaging

Limitations

not used as a structural sealant

not for all the substrates which may leak grease, plasticizers or solvents, such as oil-soaked wood

not for airtight and non-moisture environment, because the sealant needs to absorb moisture in the air for curing

not for frost or wet surfaces

not for areas continuously immersed in water or wet areas throughout the year

Health and Safety / Storage

9796 Neutral Silicone Weather-proofing Sealant has no toxicity after fully cured, but it shall avoid contact with eyes before curing. Rinse with plenty of water and seek medical treatment if contact with eyes. Touch by children shall be prohibited before curing. 9796 Neutral Silicone Weather-proofing Sealant will release low molecular substance when curing, so it is necessary for use in a ventilated environment. Shelf life is assured for 9 months from date of manufacture when stored under 27℃ in a cool and dry place.
