Mesh 100
CENOLITE
2621900090
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.
▸ 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.
▸ 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.

▸ Roof heat-insulation coatings for reduced surface temperature
▸ Exterior wall thermal barrier paints and energy-saving coatings
▸ Waterproof insulation coatings requiring lightweight film build
▸ Industrial equipment coatings where heat transfer reduction is required
▸ Functional wall coatings, texture coatings, and repair coating systems

▸ 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.
▸ Yes. Low iron content helps minimize yellowing and maintains brightness, making coating grade cenospheres suitable for white and light-colored formulations.
▸ Their spherical shape reduces resin demand, improves flow and leveling, enhances sanding properties, and lowers density while extending coverage.
▸ Absolutely. Samples, TDS, COA, and formulation guidance are available upon request. Our technical team can assist with dispersion and compatibility trials.
