Performance Advantages of Spray PolyureaŸ Excellent environmental performance as no solvent is used
Ÿ Fast curing--can be sprayed on a sloping or vertical surface without dripping or forming traces of
flowing
Ÿ No special requirements on the temperature and humidity of the application environment
Ÿ Able to maintain excellent elasticity in low temperature; good corrosion resistance; better wear
resistance compared to epoxy and rubber
Ÿ Desired reactivity and hardness can be achieved by adjusting the formulation, with a hardness
ranging from 30A to 70D
Ÿ Seamless lining without leaving any connecting locations that lead to leaking or wearing;
excellent waterproof performance.
Ÿ Excellent durability; no powderisation or cracking in long-term
exposure to outdoor environment
Application of Spray PolyureaŸ Wastewater systems (manholes, digestors, reservoirs)
Ÿ Pipeline protection (external and internal)
Ÿ Tank cofferdam
Ÿ Tank coating
Ÿ Bridges
Ÿ Coastal steel structures
Ÿ Conveyor belts
Ÿ Wearable lining for truck and train compartments
Ÿ Theme parks
Ÿ Artificial ponds
Ÿ Swimming pools
