Silica Dioxide Powder For Water Based Coatings

Feature

Silica dioxide powder, also known as silica powder or silicon dioxide powder, is a commonly used additive in water-based 

coatings. It is a white, odorless, and tasteless powder that is made from naturally occurring silica.

Water-based coatings are formulations that use water as the main solvent instead of traditional organic solvents. These 

coatings are more environmentally friendly and have lower levels of volatile organic compounds (VOCs). Silica dioxide 

powder is added to water-based coatings for various reasons:

1. Matting Agent: Silica dioxide powder can be used as a matting agent to reduce the glossiness of the coating and create 

a matte or satin finish. It helps to scatter and diffuse light, giving the coated surface a more even and less reflective 

appearance.

2. Thickening Agent: Silica dioxide powder can also act as a thickening agent in water-based coatings. It helps to increase 

the viscosity of the coating, improving its flow and leveling properties. This allows for better control during application and 

ensures a smooth and even coating.

3. Anti-Settling Agent: Silica dioxide powder has excellent anti-settling properties, meaning it helps prevent the settling of 

pigments and other solid particles in the coating. This ensures a more stable and homogenous formulation, preventing issues 

such as color separation or uneven coating thickness.

4. Reinforcement: Silica dioxide powder can also provide reinforcement to the coating film. It improves the mechanical properties 

of the coating, such as hardness, scratch resistance, and abrasion resistance. This makes the coating more durable and 

long-lasting.

When using silica dioxide powder in water-based coatings, it is important to ensure proper dispersion and incorporation into 

the formulation. This can be achieved through mechanical mixing or the use of dispersing agents. It is also crucial to follow the

recommended dosage levels to avoid any negative effects on the coating's performance.

Overall, silica dioxide powder is a versatile additive that enhances the performance and appearance of water-based coatings. 

Its matting, thickening, anti-settling, and reinforcement properties make it a valuable ingredient in various coating applications.

USING TIPS:

* Recommend dosage is 3%-8%.  (Please adjust the dosage according to the actual product.)                                                                    

* As different formulations and conditions, suggest the user to test and make sure the dosage before using.
