Descriptions Polyurea is a type of compound reacted by isocyanate component (short to part A) and amide blend(short to part B). Following the high-solids coatings, waterborne coatings, radiation curable coatings, powder coatings and other pollution free coating technologies, Spray Polyurea Elastomer (referred SPUA) technology is a solvent-free, pollution-free green application coating advanced technology developed to meet environmental requirements in nearly two decades abroad. It’s a revolutionary leap of traditional construction technology which combines new technology new material and new procedures together. Its a breakthrough for changing the traditional anticorrosion protective concept and set up a higher standard for the material protection industry.
Characteristics SWD two component solvent free environment friendly pure polyurea coating is developed bySWD Urethane Co., USA in 1992. Based on the high reactivity and fast curing property, it can be sprayed forming at any bent, inclined and vertical surface without sagging. With super adhesive strength and impact resistance characteristics, the coating is flexible, impact resistant and seamless that able to completely insulate air and water and oxygen penetration. It integrated anticorrosion, waterproof, wear resistance, aging resistant performances, no pulverization and crack peel up or fall down after long- term outdoor work with alternating ambient conditions of cold, heat, rain and snow.
