FAQ – Coating Grade Cenospheres

❓ What is the typical particle size range for CENOLITE 910?

▸ D50 = 45-60 μm, D98 = 105-140 μm, optimized for thin-film and industrial coatings.

❓ Why is iron content important for coating applications?

▸ Low iron (≤6%) ensures lighter color and better opacity, especially for white or light-colored paints and primers.

❓ Do you test dispersion performance?

▸ Yes, every batch is tested with high-speed mixing and Hegman gauge to ensure no agglomeration and uniform dispersion in paint systems.

❓ Can you provide a COA with every shipment?

▸ Yes, each shipment includes a digital Certificate of Analysis with batch-specific test results.

❓ Can you customize particle size for a specific coating resin?

▸ Yes, we offer custom cuts (e.g., D50=30-40μm for high-gloss finishes) upon request.
