Adhesion(MPa), level ≥6
Resistance to neutral salt spray(3000h) not blister, not rust,  not fall off; scratches rust width of less than 2mm.

·The product application case of company

Polyasparticpolyurea coating

·The main characteristics
Polyasparticpolyurea coating is a new type of aliphatic, slow reaction, high performance, environment-friendly coating material that appears in the polyurethane industry this year, known as the third generation of polyurea. The products with low VOC emissions of construction, curing time is adjustable, strong adhesion, high hardness, excellent weather resistance and anti-corrosion performance.

·The main application
Polyasparticpolyurea coating mainly include polyasparticpolyurea elastic exterior wall coating and polyasparticpolyurea wear-resistant floor coating。Polyasparticpolyurea elastic exterior wall coating is used for exterior wall waterproof and external wall decoration, it also can be used in large building exterior wall, villa exterior wall, civil waterproof, landscape decoration and waterproof and other fields. Polyasparticpolyurea wear-resistant floor coating used for flat waterproof and floor decoration. It can be widely used in office floor, workshop floor, large building and roofing waterproofing, bathroom and other areas of water
