Polyurethane Waterproof Building Coating (PU820)
Polyurethane coating applied on substrates, to form a film, soft and seamless sealing film by chemical reaction with moisture in the air
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 toxity 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-effectice: The coating expands a little after curing, which means it turns a little bit thicker after curing.

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
