Silane Emulsion Water Repellent RJ-WP08E has multi-function, which can be waterproofing and decrease water, widely used as overall waterproofing agent for cement mortar.

The waterproof mechanism:

When the waterproofing agent, cement mortar, concrete and water be hydrated together, the waterproofing agent will cross-link three-dimensional reticular silicate in the alkaline catalyst firstly. Then block the capillary pores of cement hydration process. At the same time, the water repellent film is formed on the surface and pore walls of cement. Therefore, the waterproof agent has double waterproof functions. The waterproofing agent contains a certain amount of non-ionic, anionic surfactants, which can reduce the frictional resistance of cement mortar or concrete, improve mobility, and workability, playing a role of sufficient water reduction. In the maintenance process of the cement, it can make the structure more closely and enhance the strength.
