3M™ Ceramic Microspheres are high-strength, inert fine particles with intrinsic hardness. 3M microspheres are engineered to help you reduce costs, increase solids, enhance properties, and improve processability.
- Lower viscosity and improved flow
Unlike many irregularly shaped fillers, 3M ceramic microspheres roll easily over one another, similar to ball bearings. This contributes to lower viscosity, better flow, and improved sprayability.
- Higher filler loading to reduce costs
With the lowest surface area to volume ratio of any shape, 3M ceramic microspheres can help reduce resin demand and increase volume loading capacity. Smaller spheres may fill voids between larger ones to enhance packing for higher solids/lower VOCs, and reduced costs.
- Burnish resistance and hardness
Mohs 7 hardness and spherical shape contribute to increased burnish resistance and hardness of the finished surface. This helps surfaces stay new-looking longer to save the time and cost of touch-ups or repainting. With ordinary fillers, soft or jagged particles on the surface o Powder coating with a spherical dispersion improves material handling for often break or wear away. consistently smooth surfaces.
High-scrub, crystalline silica-free interior paints maintain optical qualities after repeated cleaning
- Gloss control
Many gloss control materials can increase viscosity. But increasingly higher levels of 3M ceramic microspheres can help incrementally lower gloss without significantly increasing viscosity in many applications.
