Product Description
STWD9523 is a one component aromatic polyurea anticorrosion waterproof protective coating, it has excellent adhesive strength with concrete base. The unique chemical structure makes it has good infiltration capacity into substrate, high resistance to chemical medium such as many organic acid or inorganic acid. It has excellent strength and high flexibility to avoid concrete breakdown from ground subsidence or cold and hot change shrinkage.
Product features and advantages.
*High solids, low VOC emissions
*Easy to apply, brush, roller, air spray or airless spray all suitable.
*High physical properties of wearable, impact resistance and scratch resistance
*Excellent waterproof performance
*Excellent chemical resistance, can withstand certain concentration of acid, alkali, salt, oil, organic solvents etc.
*Excellent adhesion force, fast bonding well on the surface of steel, concrete, wood, fiberglass and other substrates.
*Wide temperature requirements, can be used in environments of -50 ºC ~ 120ºC.
*One component material, easy operation without ratio mixed, reducing labor costs
Typical use Chemical, pharmaceutical, building materials, printing and dyeing, steelmaking, power generation, food and other industries, urban sewage treatment plant and the application of internal and external wall of pipelines.
