What Is 0.9 g/cm3 Cenosphere for Paints And Coating?

▸ This product is selected for coating systems where film smoothness, color stability, and lower formulation weight are important.

▸ The hollow ceramic structure provides low density while the spherical particle shape supports flow, leveling, and dispersion.

▸ It is especially suitable for paint and coating formulas after particle size, pH, and resin compatibility testing.

Key Performance Characteristics

Coating Compatibility: Stable ceramic chemistry and neutral pH support many water-borne, solvent-borne, and powder systems.

Smooth Application: Spherical morphology helps improve leveling, sanding feel, and sprayability.

Low Iron Control: Low iron grades help reduce color interference in white and light-colored coatings.

Density Reduction: Hollow particles reduce coating weight while maintaining film volume.

Thermal Function: The hollow structure can contribute to heat-insulation coating performance.

FAQ

❓ What particle size is best for coating applications?

▸ This 100 Mesh 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.
