Detailed Description:
Descriptions Polyurea is a coating reacted by isocyanate component (referred to as Part A) and amide component (the R component). Following the high-solids coatings, waterborne coatings, radiation curable coatings, powder coatings and other low (no) pollution coating technologies, Spray Polyurea Elastomer (referred SPUA) technology is a new solvent-free, pollution-free green construction technology which is developed to meet environmental requirements in nearly two decades abroad. Praised as “omnipotent” ideal material in the coating technology field, Spray Polyurea Elastomer technology is the greatest discovery in the late 20th century. It’s a revolutionary leap of traditional construction technology which combines new technology new material and new procedure together. It established a higher standard for the material protection industry which broke the traditional concepts of anticorrosion and protection.
Characteristics SWD Urethane Co., USA developed a two components solvent free environment friendly pure polyurethane coating in 1992. It has high reactivity, fast cure be sprayed forming at any bent, inclined and vertical surface, without sagging, high elastic, dense and seamless material can completely insulated air, water, oxygen penetration, with super adhesive strength and impact resistance properties. It’s integrated anticorrosion, waterproof, wear resistance, aging resistant performances together. No pulverization and crack peel up or fall down after long- term outdoor work with the alternating impact of cold, heat, rain and snow. Polyurea has a history of more than 20 years in North America and other developed countries, it has very strong market demand and widely used in many fields such as aviation, traffic, petroleum, chemical, metallurgy, power generation, construction and move property etc.
