Large Area Spraying Polyurea

Polyurea is sprayed by semi-prepolymer, amino-terminated polyether, amine chain extender and other raw materials. It has strong hydrophobicity, is insensitive to environmental humidity, and can even be sprayed on water (or ice) to form a film. It can be constructed normally under extremely harsh environmental conditions, and its performance is particularly prominent. The appearance of polyurea completely broke the traditional concept of anti-corrosion and protection, and set a higher standard for the material protection industry. Polyurea coatings are flexible, rigid and colorful. They are compact, continuous and seamless. They completely isolate moisture and oxygen from the air. Their anticorrosive and protective properties are unparalleled. It also has many functions such as wear resistance, waterproof, impact resistance, fatigue resistance, aging resistance, high temperature resistance, nuclear radiation resistance and so on. Therefore, it is widely used in many fields.
