Brand:
Microblast® is a natural mineral abrasive, reddish/pink in colour, predominantly almandite consisting of sub-angular particles mined from an alluvial resource.
- Produces a rough, uniform, matte finish with a sharp texture.
- The grain shape and high bulk density result in a fast cutting and stripping abrasive.
- May be disposed of in non-hazardous waste dumping sites unless contaminated with other hazardous materials.
- Can be recycled up to five times without loss of performance, resulting in lower shipping, handling, collection and disposal costs.
- Blast cleaning using garnet produces significantly lower dust emissions than other blast abrasives – resulting in minimal disruption and danger to adjoining operations, improved operator visibility, and lower cleanup costs.
APPLICATION
Microblast® is the abrasive of choice for all water jet cutting and abrasive blasting applications. It is also used as an alternative to aluminium oxide for general cleaning, deburring and decorative finishing. Its unusually attractive colour lends itself to decorative and architectural uses as well.TECHNICAL DATA
