SP831 is one component polyurethane coating applied on substrates, to form a film, soft and seamless sealing film by chemical reaction with moisture in the air.

#Key Features
1. Pure polyurethane sealant, environment-friendly
2. Contains no asphalt, tar or any solvents, no harm to construction personnel
3. Free from pollution to the environment, no toxicity after curing, no corrosion to base material, high solid content
4. One component, convenient for construction, no need of mixing, surplus products should be kept in good airproof package
5. Efficient: high strength and elasticity, resistant to acid and alkali, excellent bonding effect with concrete, tile and other substrates
6. Cost-effective: the coating expands a little after curing, which means it turns a little bit thicker after cured
