Crystalline Silica Filler for Paint Formulations 600–2500 Mesh
Crystalline silica filler for paint and coating formulations, covering 600–2500 mesh with whiteness ≥95 and a source-backed focus on oil absorption, dispersion, viscosity control, mobility and rub resistance. Confirm the target binder and grade before sampling.
A Mineral Filler for Paint and Coating Development
This page is built around paint and coating formulation work. The approved application references oil absorption, dispersion, viscosity control, mobility and rub resistance, with whiteness and hardness as key grade references. These are evaluation directions for the formulator, not blanket performance guarantees for every binder or coating system.
Formulation Questions to Resolve
- What binder, pigment package and coating type will be tested?
- Which grade within the 600–2500 mesh reference is required?
- How will oil absorption, dispersion, viscosity and mobility be measured?
- Which rub-resistance and appearance criteria must the trial meet?
Using the Data in a Coating Trial
Compare the target mesh and whiteness with the approved chemistry, moisture, hardness and particle-size data. Then test the selected grade in the customer’s formulation under defined loading and mixing conditions. Final suitability should be decided from the buyer’s own coating results.

Paint and Coatings Filler FAQ
Paint and coating formulations evaluated for oil absorption, dispersion, viscosity control, mobility and rub resistance.
The product reference is 600–2500 mesh.
Review the chemistry, moisture, whiteness, hardness and particle-size distribution with the intended binder system.
No. The final grade and performance must be confirmed through the customer’s formulation trial.
