Silicone Hydrophobic Powder

Silicone Hydrophobic Powder

WS80 Powder

Waterproof cement-based building materials for added durability with less maintenance

 

 

Product Overview

WS80 Powder is developed on the basis of the technology of encapsulating hydrophobic additives in a hydrophilic shell, that is, a powdery silane-based product which is obtained by coating the silane through spray drying with a water-soluble protective colloid and an anti-caking agent. WS80 subtly combines two contradictory mechanisms (waterproof and dispersibility) together, so that the hydrophobic mortar can be stirred effectively and uniformly in a short time, and dry powder mortar products with strong hydrophobic properties can be formulated.

Range of Application

WS80 Powder is used to improve water resistance and durability of cement-based products.

Recommended Application:

Joint filler

Waterproof mortar

Concrete,

EIFS

Method of Use

Package into finished products after mixing with other dry powder components evenly, and use it after mixing with the recommended amount of water on site.

The recommended dosage is 0.2%-0.5% by weight of dry powder, which will hardly affect the compressive strength of the material.
