Product Description
SWD8526 is a single component aliphatic polyurea anticorrosion waterproof protective coating. Due to the use of high-strength resin, aliphatic isocyanate, and some special additives for pre-polymerization, the resulting coating has high viscosity and can be applied with a scraper. This product not only has excellent high elasticity, high strength, wear resistance and impact resistance, but also has excellent anti-corrosion and weather resistance property. It does not pulverize or discolor after long-term outdoor use, and has good decoration effects.
Product features and advantages
*High solid content, low VOC emission
*The application method is simple and can be applied by brush, roller, air spray or high-pressure airless spray.
*Good physical properties such as wear resistance and impact resistance.
*Excellent waterproof performance.
*Excellent resistance to chemical medium corrosion, capable of withstanding certain concentrations of acids, alkalis, salts, oils, organic solvents, etc
*Excellent anti-aging performance, non-powdering and non-discoloration for long term outdoor use
*Excellent adhesion, can quickly and firmly bond to the substrate surfaces such as steel, concrete, wood, glass fiber, etc
*The application temperature range is wide, ranging from -50ºC to 120ºC condition.
*It is single component material, easy to apply, without the need for mixing, reducing labor costs
Product application scope
Anticorrosion and waterproof protection for industries such as petroleum, chemical, transportation, construction, power, and containers. Such as for bridge maintenance, building roof waterproofing, water conservancy dams, hydropower station building waterproofing, etc.
