Glass microspheres
Glass microspheres Glass micro beads Glass pigment

This lustrous glass pigment reflects brightly when a light source is directed onto its surface. You may recognise this reflective effect from the grey strips that are seen on high visibility vests. It is an additive that can be added to water and solvent-based systems including clear varnishes, paint or print binders.

The original application for glass microspheres was a simple coating that was applied to theatre and cinema screens almost 100 years ago. The microspheres were added to a clear medium and were then applied by hand to the screen material. The microspheres reflective properties allowed the movie watchers to enjoy a brighter projection of the film they viewed.

Glass microspheres are now widely used in thousands of applications and are used by a wide range of industries including fashion, aerospace, automotive, marine, road markings, health & safety, military, fashion, screen printing inks, paints, varnish, art and print, and design.

These glass microspheres are a scaled-down micro version of the cat's eyes that separate the lanes of a highway (motorway) in the dark. The bright reflection can only be seen if viewed from directly behind the light source (headlamps).

This grey reflective powder is composed of tiny microspheres of solid soda-lime glass that has been semi coated with aluminum microfilm. The beads have a particle size of between 55 and 75µm. The 95% sphericity of these microbeads allows for an even particle distribution with a uniform and bright reflection that can be achieved when a light source is directed at the beads. The white micro beads are manufactured from the same glass but without the aluminum, coating applied. The white spheres have a particle size of 45-55µm.

You can mix 10-20% of this product with our glitter binder. Please click here to view SFXC glitter binder.

Always test these products before production, print runs or end products. Some clear binder may tarnish the reflective properties of the beads so; please test a small amount with your chosen medium before mixing a large batch.
