FUNCTION :
Abrasive Blasting: The angular profile of crushed glass grit allow for aggressive surface profiling. The product delivers very low grit embedment and is therefore regularly specified as a secondary process to remove embedment caused by other friable abrasives. Suitable for blasting of all non-ferrous metals, weld seams prior to inspection. 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.
