Product Features

  1. Apply with VOC emission standards.
  2. Appearance-refreshing and tidy:
    It can prevent the growth of fungi and mold, and keep the internal and external surfaces of the building fresh and tidy for more than 20 years.
  1. Resistant to rain for more than 20 years.
  2. Improves the surface properties for water repellency.
  3. Compared with traditional oil-based organosilane water repellent which includes flammable VOC and would release VOC into environment, HENGDA-NW01 is used by diluted in water (5-10 wt.%) which reduce 90-95% VOC.


It can prevent mold growth, frost, leakage, stains, premature aging, flaking, corrosion of steel bars, etc., and keep the internal and external surfaces of the building clean and tidy for more than 20 years.

It can penetrate deeply into the building substrate, making the 5-200nm pores of cement-based materials hydrophobic, which is impossible with other traditional film-forming products.
