3M™ Ceramic Microspheres White Grade W-210 are solid, engineered particles made of alkali aumino silicate ceramic with a typical whiteness (L Value) of 90 or greater and an effective d90 particle size of 12 μm.
These unique particles offer formulation flexibility and may allow to have formulations with lower VOCs or higher filler loads due to lower resin demand – as well as excellent scrub and burnish resistance. They are also UV transparent down to 250 nm and have applications in radiation-curable thin-film coatings.
