Polyurethane road joint sealant
Product Description :
Polyurethane road joint sealant is a new type of two-component room temperature curing sealant material. It boasts excellent bonding strength, elasticity, resistance to aging, and durability in extreme temperatures, with a long service life and quick and easy application. It is widely used for road joint construction on expressways, airport runways and aprons, bridge expansion joints, underground tunnels, reservoir embankments, and other similar applications.
Polyurethane road joint sealant is a new type of two-component room temperature curing joint material. It boasts excellent bonding strength, elasticity, resistance to aging, and ability to withstand high and low temperatures, with a long service life and quick, convenient application. It is widely used for highway joints, airport runways and aprons, bridge expansion joints, underground tunnels, reservoir embankments, and other joint construction projects.
I. Performance and Features:
The product is a two-component system: Component A is a polyurethane prepolymer, and Component B is a thick liquid.
2. High product strength, good elongation, high solid content, and excellent bonding performance.
3. The product is wear-resistant, waterproof, and temperature-resistant, with superior performance.
4. Free from coal tar, petroleum resin, asphalt, and organic solvents, non-toxic to both humans and the environment.
5. When encountering vertical surface construction, it exhibits good thixotropic properties and does not run.
