1.Description:

PS500D sewage water treatment pool special polyurea is a 100% solid content aromatic polyurea elastomer. It it stable in anticorrosion property, suitable for corrosion environment, with superior anticorrosion effect than traditional anticorrosion material which can greatly improve the surface life of sewage pools. It has been widely used in the sewage treatment pool project in home and abroad..

2.Features:

● Solvent free, 100% solid content, safe, environmentally friendly and odor free.;

● Rapid cure, can be sprayed forming on any bent, slope and vertical surfaces, no sagging;

● Dense coating, seamless, with good flexibility;

● High adhesive strength, can fast bond well on many substrate like steel, concrete, wood, fiber glass etc;

● Excellent impact resistance and abrasion resistance;

● Excellent anticorrosion, chemical resistance to acid, alkali and salt;

● Excellent impervious and waterproof performance;

● Excellent resistance to temperature variation;

● Ecellent durability to reduce maintenance cost of service life;
● Extend the service life of sprayed structure;
