SWD reinforced concrete anticorrosion waterproof protective coating
Descriptions
The reinforced concrete is the largest amount and most widely used construction structural materials in the world. The reinforced concrete structure used crack in the various environment of alternative hot and cold, dry and wet and load impact. It will lead to the steel structure exposed to the corrosive environment when the corrosive media such as acid rain penetrated into the interior structure of reinforced concrete and made steel bar rusted. Plus the joint action of water freeze and concrete internal stress the corrosion of concrete structure will expand and decrease its strength and stiffness. The more serious cracks or peel-off may occur. In order to protect and extend the application life of reinforced concrete structure, SWD Urethane Co., USA developed SWD one component polyurea reinforced concrete anticorrosion water-proof coating with high properties of anticorrosion waterproof. It has already become the preferred concrete protective coating in the market of Europe and USA.
Characteristics
Based on the unique technology formulation, took the high-performance one component polyurea resin prepolymer as main film- forming materials, SWD polyurea reinforced concrete anticorrosion waterproof coating integrates various technologies together and contains large amount of urethane bond, biuret bond, allophanate bond and unsaturated grease bond. It specially includes hydrogen bond that makes large cohesive force among high molecules inside the film. It caused coating possessed super properties of anticorrosion, waterproof, wear resistance, temperature variation, anti-aging, chemicals resistance etc. Compared with traditional anticorrosion waterproof products, SWD reinforced concrete anticorrosion waterproof coating has better protective effect and pricing competitive. The application life can reach above 15 years if strictly confirm the regular application standard.
