Product Description
STWD9013 floor special polyurea is 100% solid content aromatic polyurea elastomer. It has excellent flexibility and abrasion resistance, compared with traditional epoxy and carborundum floor coating be too hard and fragile, this coating is impact resistance and wearable. It also has been used on the food processing and pharmaceutical flooring field because it is 100% solid content, without solvent.
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, good adhesive strength
*Excellent impact resistance, abrasion resistance
*Excellent corrosion resistance and chemical resistance to acids, alkali, salts etc.
