The electric power industry is a critical part of economic infrastructure. The facilities should have effective application life which be required excellent anticorrosion waterproofing materials and advanced protective technology. Spray polyurea elastomer is a breakthrough of the traditional anticorrosion protection concept and integrated new materials, new technology and new process together. With excellent comprehensive physical properties and anticorrosion performance recently it has been successfully used in the power industry under various complicated corrosion environment.
2. Characteristics
It is high reactive and rapid cure and able to be sprayed forming on any bending surfaces of slopes and vertical side without sagging or falling down problems. The coating film is flexible, dense and seamless, high adhesive strength with substrate and excellent anticorrosion waterproof properties, no bubbles and peel off during long-term immerse of various liquid conditions. The working temperature could be boiled water in 100 ℃ without deform and cracks but keep high tensile strength, impact resistance and excellent chemical resistance performance.
