Blastrite®
Garnet (Natural Mineral Abrasive)
Applications
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.
- Hardness > 6 Moh scale (Section 4.1.2 of SSPC- AB1)
- Specific gravity Ave. 2.7 (ASTM C128-15)
- Bulk density ≈ 1.39 kg/m³
- Free silica Not detectable
- Conductivity <250 μS/cm (ISO 11127-6)
- Moisture content <0.05% (ASTM C566-13)
- Oil content None (ASTM D7393-16)
- Shape Angular
- Storage Dry, sheltered storage conditions
- Packaging 1.5T Bulk bags or unitised 25kg & 50kg bags
- 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.
- Silica, crystalline: None
- Si02: 40 – 50%
- Fe2O3: 15 – 35%
- MgO: 15 – 25%
- Al2O3: 5 – 10%
- CaO: 5 – 10%
- Cr2O3: 1 – 5%
