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.
