99% Silica Powder For Coating Casted Paper

Feature

99% Silica Powder is a high-purity form of silica that can be used for various applications, including coating casted paper. 

Silica powder is known for its excellent heat resistance, electrical insulation properties, and low thermal expansion. When 

used as a coating on casted paper, it can provide additional strength, durability, and protection.

To use 99% silica powder for coating casted paper, you will need the following materials and equipment:

1. 99% silica powder: Purchase high-quality silica powder with a purity level of 99%. This ensures that the coating will have 

the desired properties.

2. Casted paper: Prepare the paper that you want to coat. Casted paper is a type of paper that has been formed by pouring a 

slurry of pulp onto a screen and allowing it to dry.

3. Mixing container: Use a clean container to mix the silica powder with a suitable liquid binder. The binder will help the silica 

powder adhere to the casted paper.

4. Liquid binder: Choose a suitable liquid binder that is compatible with the silica powder and the casted paper. Common options 

include water-based adhesives, acrylic binders, or specialty binders designed for paper coatings.

5. Mixing tool: Use a spatula or a stirring rod to mix the silica powder and liquid binder thoroughly. Ensure that the mixture is homogeneous and free of lumps.

6. Application tools: Depending on the desired coating thickness and application method, you can use a brush, roller, or spray 

gun to apply the silica powder mixture onto the casted paper.

Steps to coat casted paper with 99% silica powder:

1. Prepare the silica powder mixture: In the mixing container, combine the 99% silica powder with the liquid binder according to 

the manufacturer's instructions. Mix well until a smooth, homogeneous mixture is obtained.

2. Adjust the viscosity: If the mixture is too thick, you can add a small amount of water or other compatible solvent to adjust the 

viscosity to a suitable level for application. Stir well to ensure uniformity.

3. Apply the coating: Using the chosen application tool, apply the silica powder mixture onto the casted paper. Ensure an even and

consistent coating thickness. If necessary, apply multiple layers, allowing each layer to dry before applying the next.

4. Dry the coated paper: Allow the coated paper to dry completely. The drying time may vary depending on the environmental 

conditions and the thickness of the coating. Follow the manufacturer's instructions for the recommended drying time.

5. Optional curing: If required, you can further enhance the coating's properties by subjecting the coated paper to a curing process. 

This may involve heating the paper to a specific temperature for a specific duration. Follow the manufacturer's instructions for the

recommended curing process.

By following these steps, you can effectively coat casted paper with 99% silica powder. The resulting coated paper will have improved

strength, durability, and protection, making it suitable for various applications.
