Product Description
Polyurethane Material for Special Expansion Joints for Bridges and Roads EX-802
Product Overview
EX-802 is a 100% solid 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, it can also be customized into high flame-retardant and anti-static polyurea coatings according to user needs.
Characteristics
- Solvent-free, 100% solid content, safe, environmentally friendly, and odorless
- Rapid curing, capable of being sprayed and formed on any curved, inclined, and vertical surfaces without sagging.
- Dense coating without seams, with good flexibility and toughness.
Key Advantages
- Strong adhesion, capable of quickly bonding to steel, concrete, wood, fiberglass, and other substrates.
- Excellent impact resistance and wear resistance.
- Excellent corrosion resistance and resistance to chemical media, such as acids, alkalis, and salts.
- Excellent waterproof performance
- Good shock absorption performance
- Superior temperature stability .
- Rapid curing, enabling the construction area to be quickly restored for use.
- Outstanding durability reducing lifetime costs.
- Extending the service life of the sprayed structure.
