STWD9003 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.
Product features and advantages
*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.
