Composition: Silane-based additive Hydrophobic agent HP-70

HP-70 is an encapsulated silane in powder form and it produced by spray-drying. It provides outstanding hydrophobizing and water-repellent properties on the surface and bulk of cementitious based building mortars. The active ingredient of HP-70 is released when the mortar is mixed with water and it subsequently binds covalently to the inorganic mortar matrix. HP-70 is easy to mix during production of cementitious based dry mix products. It improves the water resistance and durability of cementitious based products even at very low dosage. It is also fully efficient in alkaline medium.
