Silicone water repellent

Using high-tech carrier and slow-release technology, the active substance can be released in time after contact with water, and form hydrophobic protection after curing of the substrate. As a hydrophobic additive, it can be used in dry-mixed mortar systems with cement and minerals as raw materials to prevent the absorption of water by capillaries/pores in the material, greatly reducing the water absorption rate of the base, and providing the hydrophobic performance of the material. Especially suitable for caulking agent, waterproof mortar, as well as external wall insulation system plaster mortar, decorative mortar.

Product Description

Product Description

Commodity name: Silicone water repellent

1. product introduction

2. product advantages and characteristics:

1. High activity, good dispersion, free flowing, white powder
2. Provide the overall waterproof material, not the substrate surface film
3. Good fluidity and dispersion performance in dry powder
4. Easy to disperse in water, does not affect the wetting, stirring and working performance of the dry powder
5. It has the properties of inhibiting the base material from alkalizing and enhancing the freeze-thaw resistance of the base material, which is conducive to maintaining the beauty and color of the base material.
6. High weather resistance, UV resistance, providing long-term hydrophobic protection of the substrate, and will not weaken the strength of the substrate

3. typical physical properties:

Parameters	Results
Appearance	milky white, free flowing powder
Silane active content	20% w/w
Specific gravity, 25 ℃	300 g/L
Average particle size less than 500m	100% w/w
pH (10% in water)	Neutral or weakly alkaline
residual moisture	<2% w/w

4. method of use:

1. Silicone water repellent for dry powder state, can be mixed with other dry powder materials in the mixing equipment to produce all kinds of dry powder mortar products.

2. To avoid long time, high shear stirring, in order to prevent the powder temperature rise. The dry mortar product containing the water repellent is usually added slowly while stirring in a water container, but too strong stirring should be avoided to prevent the introduction of air. In the state of ready-mixed with water, water can be added to stir and dilute before use. Just stirred good material, depending on the situation of other additives, stand for 1 to 5 minutes after use.

The amount of silicone added is generally 0.2-1.5 of the amount of dry powder (dry powder), depending on the waterproof requirements of the substrate. It is recommended to determine the applicable addition amount after laboratory testing before use.

5. packaging, storage and shelf life:

1. This product is 20Kg composite bag, other big bag packaging or barrel, can be customized according to customer requirements and quantity.
2. It should be stored in a dry place and away from sunlight.
