Product Description
STWD9528 is a single component aromatic modified polyurea waterproof anti-corrosion protective coating material. This product has good adhesion to concrete and steel substrates, and it is easy to apply without the need of specialized polyurea spraying equipment. Due to its unique chemical structure, the film-forming coating has good resistance to chemical medium and excellent waterproof performance, making it an ideal material for waterproof and anti-corrosion protection applications. The characteristics of high elasticity and high adhesion are particularly suitable for the waterproofing of building roofs, balconies, bathrooms, exterior walls, and basements, especially for the repair of old SBS membrane material roofs and the anti-corrosion and waterproofing of old colored steel tile roofs.
Features and benefits
*High solid content, low VOC emissions
*The application method is simple and does not require professional polyurea spraying equipment. It can be applied by brush, roller, or high-pressure airless machine.
*The coating has good flexibility, strong leakage resistance, and excellent waterproof performance.
*Excellent resistance to chemical medium corrosion, capable of withstanding certain concentrations of acids, alkalis, salts, oils, organic solvents, etc
*Excellent adhesion, which can quickly and firmly bond to the surface of substrates such as concrete, steel, wood, glass fiber, etc
*Wide temperature range for use ranging from -50 ºC to 120 ºC
*It is one component material, easy to apply, without the need for mixing, reducing labor costs
Application scope
Construction, water conservancy, transportation, chemical industry, electricity, etc. For example, waterproofing of building roofs, bathrooms, exterior walls, basements, water conservancy dams, hydropower station buildings, etc. Especially for the repair of old SBS membrane material roofs and the anti-corrosion waterproofing of old colored steel tile roofs.
