Introduction of High-purity Silicone Hydrophobic Powder
Methyl is modified and dried with high-purity siloxane. The carrier and slow-release technology are used to release the active substance in time after it meets water, and form hydrophobic protection after the substrate is cured. As a hydrophobic additive, it can be used for the absorption of water by capillaries/pores in mortar system materials made of cement, gypsum and minerals, which greatly reduces the base water absorption rate and provides hydrophobic properties for the material. It is especially suitable for water-filled mortar, gypsum products, and plastering mortar and decorative mortar for exterior wall insulation systems.
How to use High-purity Silicone Hydrophobic Powder
1. The silicone hydrophobic agent is in a dry powder state and can be mixed with other dry powder materials in a mixing equipment to produce various dry powder mortar products.
2. Avoid stirring for a long time and under high shear force to prevent the temperature of the powder from rising. Usually, in a container filled with water, slowly add the dry powder mortar product containing the hydrophobic agent while stirring, but avoid too strong stirring to prevent the introduction of air. In the state of premixing with water, water can be added to dilute it before use. The newly mixed material needs to be left to stand for 1 to 5 minutes before use, depending on the condition of other additives.
3. The amount of silicone added is generally 0.2%-1.5% of the dry powder dosage (dry powder), depending on the waterproof requirements of the substrate. It is recommended to determine the appropriate amount of addition after laboratory testing before use.

Features of High-purity Silicone Hydrophobic Powder
1. High activity, good dispersibility, free flow, white powder
2. Provide overall waterproofness of the material, and do not form a film on the surface of the substrate
3. Good fluidity and dispersibility 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 ability to inhibit alkali efflux of the substrate and enhance the substrate's resistance to freezing and thawing, which is beneficial for the substrate to maintain its beauty and color.
6. Highly weather-resistant and UV-resistant, it provides long-term hydrophobic protection for the substrate without weakening the strength of the substrate.

FAQs of High-purity Silicone Hydrophobic Powder
What is the mechanism of action of high-purity silicone hydrophobic powder?
The main component of high-purity silicone hydrophobic powder is organic silane substances containing active groups, which can form a hydrophobic film on the surface of the material to prevent the penetration of moisture.
How to use high purity silicone hydrophobic powder?
When used, it is usually necessary to add hydrophobic powder to mortar, paint or other materials in a certain proportion, and ensure that it is fully mixed.
How long is the validity period of hydrophobic powder?
The expiry date will vary depending on the specific product, but generally hydrophobic powders will retain their effectiveness for a longer period of time if stored correctly. The waterproofing effect after application can last from a few years to a dozen years, depending on environmental conditions and construction quality.
Will hydrophobic powder affect other properties of building materials?
When used correctly, hydrophobic powders generally do not significantly affect other properties of building materials, such as strength and adhesion. However, in some specific cases, the formulation may need to be adjusted to ensure optimal results.
Is hydrophobic powder harmful to human body?
Generally speaking, high-purity silicone hydrophobic powder is safe, but you still need to follow safe operating procedures when using it and avoid inhaling dust or direct contact with skin and eyes.
