Glass grit
Trade name
Starbead® Grit
Description
A silica-free, durable, chemically inert and granular particle that offers aggressive surface profiling and removal of a variety of coatings.
Application
- Abrasive Applications: FEPA-graded for coated papers and belts, standard grades for surface finishing by blasting
- Inert Fillers: Graded to customer specifications for use as fillers in rubber, plastics, industrial flooring (non-skid), brick-fluxing agent, sintered mosaic tiles, tile glaze and filtration.
- Decorative: Special effects. The angular particles in crushed glass grit allow for aggressive surface profiling and removal of coatings such as epoxy, paint, alkyds, vinyl, polyurea, coal tar and elastomers.
Advantages
- Silica-free.
- Non-toxic and inert.
- Manufactured from 100% post-consumer recycled bottle glass, thus benefits the environment by diverting waste from landfills.
- Produces a whiter, cleaner finish relative to mineral/slag abrasives.
- Lighter weight than many slags, allowing for increased consumption efficiency and production time - up to 30-50% less glass grit used.
