Paint Industry
Paint industry quartz is a finely ground, high-purity micronised quartz used as a filler (extender) in paints, primers and industrial coatings. In paint, quartz increases mechanical strength, abrasion resistance and film hardness while providing matting and body. High-purity (typically SiO₂ 99.8%) and chemically stable micronised quartz gives coatings durability and consistent performance.
How to Choose Paint Quartz?
Several criteria determine paint quartz. Grain size (fineness) governs the balance between gloss and matting, the body and the surface texture of the paint; finer grinding gives a smoother film. High SiO₂ purity and chemical stability ensure the quartz does not react with the paint chemistry and forms a long-lasting film. A Mohs hardness of 7 increases the abrasion and scratch resistance of the coating. A stable composition provides repeatability in the formulation.
Recommended Product for Paint
Micronised quartz with a fine, controlled grain size is used in paint and coating formulations. We can determine the appropriate fineness together, based on your coating type and the desired surface characteristics.
About Paint Industry
What does quartz filler do in paint?
Quartz filler increases the mechanical strength, abrasion resistance and film hardness of the paint; it provides matting and body.
What fineness is required for paint?
Fine micronised quartz is preferred; finer grinding gives a smoother film.
