Polyaspartic Polyurea for Wear-resistant, Waterproof, Anti-corrosion, and UV Resistant EX-702
EX-702 is a 100% solids aromatic polyurea elastomer, produced through the reaction of isocyanate components with amino compound components. It requires specialized polyurea equipment for spray application. Due to its excellent waterproofing, corrosion resistance, and good wear resistance, this product is widely used in industrial and commercial waterproofing and corrosion protection applications.
Key Characteristics
- Solvent free, 100% solid content, safe, environmentally friendly, and odorless
- Fast curing, can be sprayed and formed on any curved surface, inclined surface, and vertical surface without any sagging phenomenon.
- The coating is dense, seamless, and has good flexibility
- Strong adhesion, can quickly bond to substrates such as steel, concrete, wood, fiberglass, and other materials.
- Excellent impact resistance and wear resistance
- Excellent corrosion resistance and chemical medium resistance, such as acid, alkali, salt, etc
- Waterproof and anti-corrosion: ① Excellent waterproof performance ② Good shock absorption performance ③ Excellent temperature stability ④ Rapid curing, allowing the construction area to quickly resume use ⑤ Excellent durability reduces lifetime ⑥ Extending the service service life of the sprayed structure
