3M™ Ceramic Microspheres White Grade W-410 are solid, engineered particles made of alkali alumino silicate ceramic with a typical particle size d90 of 21 microns. They have a typical whiteness (L Value) of 90 or greater.
These unique particles offer formulation flexibility and may allow to get recipes 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 radation-curable thin-film powder coatings.
