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

Special additive for
- waterproofing
- cement-based mortar systems
- plasters, renders, joint fillers, sealing mortar-s/slurries
- high degree of hydrophobicity is required with cement-based mortar systems.
