Other Name: Silicone Water Repellent, Silicone Hydrophobic Powder, Waterproofing powder for concrete, Waterproofing powder admixture, Powder Silicone Waterproofing Powder, Silicone Waterproofing Agent Powder
Equivalent Product: Silicone Hydrophobic Powder SITREN P 750, Dow Corning SHP 50, Dow Corning SHP 60
Description
Powdered Silicone Water Repellent TPD-WR50P is produced by using polyether modified silicone oil based wetting dispersant and non-ionic surfactant to firstly make silane and siloxane into non-aqueous dispersion, and then be evenly packaged by carrier dispersion.
Compared with the silicone waterproofing agent used on the surface of building materials, it can be mixed into the cement powder before the molding of cement products and solidify with water together. It can make the cement products waterproof as a whole without reducing the mechanical strength of the cement products. It is convenient for packaging, storage and it is easy to use.
Features
- Convenient for packaging and transportation, easy to use.
- Super waterproofing effect, greatly reduce the water absorption rate. For concrete and mortar, the use amount is only 0.1-0.4% of the whole materials, the 48h water absorption is far superior to standard JC 474-2008.
- It is easy to disperse in the cement mortar and water.
- Not affect the final compressive strength of concrete.
