NJ-212 Hydrophobic Agent Series is an inorganic salt-modified organosilane powder designed to enhance the water resistance and impermeability of cement-based materials. Key features include:

Preventing liquid water infiltration through surface capillary action into cured cementitious materials, significantly reducing water absorption rates while protecting material surfaces from moisture penetration;

The product’s impermeability performance correlates with its dosage, showing minimal adverse effects on compressive strength within recommended ranges.

This formulation is suitable for alkaline environments.

 scope of application

waterproof mortar,  joint filler,  gypsum board,  plastering gypsum, decorative mortar,  water-resistant putty,  tile adhesive,  anti-seep waterproof cement-based mortar

Recommended dosage

The recommended dosage of this product in various systems is 1~5‰ of the system. If the surface hydrophobic state is required to be high, the dosage can be increased, and the best dosage should be determined after test.
