Product Description
STWD9526 is a single component aromatic thick film polyurea anticorrosion waterproof coating material. It cures to form a thick-film membrane that provides excellent adhesive strength with concrete and steel structure, easy to apply without need of special polyurea spray machine. Because of the unique chemical structure, it is an ideal material for waterproof anticorrosion protection with high chemical resistance and waterproofing. The high elasticity and high strength makes it most suitable for building walls waterproof, seal water of structure crack and expansion joint, anti-seepage and leak stopping of harbor docks and dams.
Features and benefits
* high solid content, low VOC
* easy application method, use scraper to scratch the coat. Special polyurea spray machine is not needed, one hand thick film
* excellent wearable, impact resistance, resistance to scratch
* excellent waterproofing
* excellent resistance to chemical media, can withstand certain concentration of acid, alkali, oil, salt and organic solvent
* excellent adhesive strength, fast bond to the surface of steel, concrete, wood, fiberglass and other substrate.
* wide application temperature, can be applied on -50ºC~120ºC
*single component material, easy to apply that reduce the labor cost.
Application scope Waterproof of construction, water conservancy, transportation, chemical and power plants, such as the crack repair of highway, pavement, airport runway, leak repair of water conservancy, offshore dam and port dock repair etc.
