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 WR390 is a kind of highly efficient, redispersibler water repellent based on modified silanes / siloxanes in powder form. It acts as outstanding water repellency even at very low concentrations.
