Pu sealant, a commonly used adhesive in households, is composed of sodium silicate (Na2OmSiO2), acetic acid and organic silicone. Sodium silicate is easy to dissolve in water and is sticky. It is also called water glass in the south and soakine in the north.
Pu sealant is a material for bonding and sealing various glass and other substrates. There are two main categories: silicone rubber and polyurethane rubber (PU). Silicone rubber sealant is what we usually call glass glue, and it is divided into two types: acid and neutral (neutral glue is divided into: stone sealant, mold sealant, fireproof sealant, pipe sealant, etc.).
