The main ingredient of hydrophobic agent is modified organic silane or ester. The hydrophobic mechanism of modified organic silane is to prevent liquid water penetrating into solidified cement or gypsum base material through surface or capillarity, thereby greatly reducing the water absorption rate.

Guudpoly Hydrophobic Agent is mainly used in a variety of construction projects, which need waterproof, seepage prevention, moisture-proof.

The specific application field is basic engineering roof, wall, toilet, kitchen, basement, Civil air defense projects, subways, tunnels, water tanks, water towers, swimming pools, dams, piers and so on, which have requirement on impermeability and waterproof.

GUUDPOLY WR381 is a kind of highly efficient water repellent, which is based on modified organic-silanes with inorganic carrier in powder form.
