Silica nanoparticles and nanospheres are now available in distributions of less than 10% CV in the sizes of 0.25 micron, 0.5micron, 0.75 micron, 1.0 micron, 4 micron and 8 micron.
Barium Titanate Glass Microspheres are excellent for use as a functional retro reflective additive to paints and coatings. Spheres with sizes of about 50 micron (~0.002 inches) mean diameter provide a small enough size for most coatings while offering a large enough size to reflective a significant amount of light. Barium Titanate Glass Spheres are offered in both partially aluminum coated retro-reflective version for addition into transparent coatings, or as uncoated glass spherical powder for uses in colored paints.
A recent article on microspheres in Cosmetics & Toiletries magazine describes the use Solid Polyethylene Mirospheres for Effects in Color Cosmetics. Microspheres have been used in cosmetics for some time, primarily as fillers and exfoliators. Most recently scientists started to utilize light reflecting properties of microspheres for creating unique optical effects, such as optical blurring … Read more
