Silicon Dioxide Powder For Waterproof Paint For Plastic

Feature

When selecting silicon dioxide powder for waterproof paint for plastic, several factors should be considered to ensure 

optimal performance:

Particle Size: Silicon dioxide powder with fine particle size is often preferred for waterproof paint formulations as it helps 

in forming a uniform barrier on the surface of the plastic substrate.

Surface Modification: Surface-modified silicon dioxide particles can enhance their compatibility with the paint matrix and 

improve adhesion to the plastic substrate. Surface modification can also improve dispersion stability and prevent issues like 

settling or agglomeration.

Purity: Choose silicon dioxide powder with high purity to minimize impurities that could affect the performance or appearance 

of the waterproof paint.

Dispersion Stability: Good dispersion stability is essential to ensure uniform distribution of silicon dioxide particles within the 

paint formulation. This helps in achieving consistent coating properties and prevents issues during storage and application.

Chemical Compatibility: Ensure that the silicon dioxide powder is chemically compatible with other components of the waterproof 

paint formulation to avoid any adverse reactions or changes in properties.

Waterproofing Properties: Evaluate the silicon dioxide powder's ability to enhance the waterproofing properties of the paint, 

such as water repellency, moisture resistance, and durability in wet conditions.

Performance Enhancements: Consider specific performance-enhancing properties such as UV resistance, abrasion resistance, 

and mechanical strength, which can improve the overall durability and longevity of the waterproof paint on plastic surfaces.

Regulatory Compliance: Ensure that the silicon dioxide powder complies with relevant regulatory standards and safety 

requirements for use in waterproof paint formulations, particularly for applications involving contact with water or outdoor 

exposure.

Supplier Reliability: Choose a reputable supplier with a track record of providing high-quality silicon dioxide powder for waterproof 

paint applications. Consider factors such as product consistency, technical support, and reliable delivery.

By carefully considering these factors and collaborating closely with your supplier, you can select the most suitable silicon dioxide 

powder for your waterproof paint for plastic, ensuring optimal performance and durability of the coated surfaces.

Tips: 

* Before you use it, please test and make sure the dosage before using according different formulations and conditions.

* Recommended dosage is 3% -5%.
