Insulating Painting Additive Ceramic Microspheres

Mesh 100 insulating painting additive ceramic microspheres are designed for thermal insulation paints, roof heat-control coatings, and lightweight wall coating systems. This grade focuses on heat barrier performance, smooth dispersion, and lower coating weight rather than general filler replacement.

What Is Insulating Painting Additive Ceramic Microspheres?

▸ SEPPE insulating painting additive ceramic microspheres are fine hollow aluminosilicate particles selected for thermal insulation coating formulas.

▸ The Mesh 100 grade disperses more easily in paint systems than coarse cenosphere grades, helping maintain a smoother coating surface while adding hollow thermal barrier particles.

▸ It is mainly used when the coating designer wants lower heat transfer, lighter film weight, and improved coverage in roof, wall, and functional insulation coatings.

Key Performance Characteristics

▸ Thermal Insulation Function: Hollow ceramic particles create microscopic air barriers that help reduce heat transfer through coating films.

▸ Mesh 100 Fine Grade: Fine particle size is more suitable for paint dispersion, brush application, rolling, and spray coating than coarse mesh products.

▸ Lower Film Density: Low-density microspheres help build coating thickness with less weight and lower heavy filler loading.

▸ Stable Inorganic Chemistry: Aluminosilicate ceramic shells provide good compatibility with many water-borne and solvent-borne insulation coating systems.

▸ Coverage Extension: Spherical hollow particles can improve volume filling efficiency and reduce formulation weight after dosage optimization.

FAQ

❓ What particle size is best for coating applications?

▸ This Mesh 100 grade is suitable for coating systems requiring fine dispersion and smooth film appearance.

❓ Does the pH affect my paint formulation?

▸ Yes. A neutral pH of 7.0±1.0 improves compatibility with water-borne, solvent-borne, and powder systems without destabilizing the binder or causing viscosity drift.

❓ Can these cenospheres be used in white coatings?

▸ Yes. Low iron content helps minimize yellowing and maintains brightness, making coating grade cenospheres suitable for white and light-colored formulations.

❓ How do cenospheres improve coating performance?

▸ Their spherical shape reduces resin demand, improves flow and leveling, enhances sanding properties, and lowers density while extending coverage.

❓ Can I get samples and coating trial support?

▸ Absolutely. Samples, TDS, COA, and formulation guidance are available upon request. Our technical team can assist with dispersion and compatibility trials.

▸ 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?

▸ Dispersion can be evaluated using high-speed mixing and a Hegman gauge under a customer-agreed coating system, addition level, mixing speed, test duration, and acceptance criterion.

❓ 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.
