Balanced Performance for Heavy-Duty Coatings
Quartz Powder for Coating is a general-purpose product for the coating industry. It provides a great balance between cost and performance. Unlike superfine silica powder, it has a wider particle size range. This creates a denser packing structure in the coating film. The film becomes much denser and much harder for liquids to penetrate. This feature is very valuable in heavy-duty anticorrosion coatings and thick-film coatings. We have tested this product in many real-world applications. The results are consistently good.
Full Process Control for Consistent Quality
We have 6 semi-automated production lines and 2 dedicated labs. Every step from crushing and pickling to milling and grading runs under strict control. We test every batch of Quartz Powder for Coating for iron content, whiteness, and particle size. This ensures the quality never changes. A ship coating customer once said our product is "reassuringly stable." This is exactly what we promise after 25 years. Our annual capacity is 20,000 tons. We can supply many large paint makers at the same time. You can count on our supply.

Versatile Uses and Flexible Service
Quartz Powder for Coating has a very broad application base. In heavy-duty coatings, it is a strong filler for epoxy and polyurethane. It boosts the film's resistance to penetration and salt spray. In thick architectural coatings and stone paint, it works as an aggregate. It gives the coating a rich texture and good weather resistance. For road marking and floor paints, its high hardness and wear resistance extend the service life. We accept custom particle sizes. Just tell us your needs. The minimum order is 1 ton.
