Versatility Across Industries
| Industry | Primary Use | Key Benefit |
|---|---|---|
| Paints & Coatings | Functional Filler | Improves “scrub” resistance and outdoor durability; provides excellent pH buffering. |
| Glass Manufacturing | Fluxing Agent | The magnesium content improves the chemical durability of glass and aids in the melting process. |
| Ceramics | Glaze & Body Ingredient | Increases the resistance of glazes to chemical attack and thermal shock. |
| Construction | Flooring & Mortars | Provides high compressive strength and a sparkling white finish in terrazzo and wall plasters. |
| Agriculture | Soil Neutralizer | Corrects soil acidity while providing essential Calcium and Magnesium for plant growth. |
| Iron & Steel | Sintering Flux | Acts as a slag conditioner and refractory protector in steel melting. |
Pro Tip: In Exterior Wall Coatings (Textured Paints), Dolomite is preferred over Calcium Carbonate because its higher hardness and lower solubility make the paint film significantly more resistant to heavy rain and environmental pollution.
Applications
Why Choose Asteroid Microns Dolomite?
- Optimized Particle Size (PSD): We ensure a narrow PSD to maximize packing density in your formulations, leading to lower resin/binder consumption.
- Consistent MgO Content: We maintain a steady Magnesium Oxide levels (typically 18% – 21%), ensuring predictable results in glass and ceramic batches.
- Ultra-Low Impurities: Our multi-stage magnetic separation and washing processes remove trace metals that cause discoloration.
- Excellent Dispersion: Our powder grades are engineered to disperse rapidly in both water-based and solventbased systems.
Our Core Varieties
At Asteroid Microns, we provide Dolomite tailored to your specific chemical and physical needs:
- Micronized Dolomite Powder: Ultra-fine grades (down to 5 microns) designed for high-end paints, adhesives, and polymer masterbatches.
- Dolomite Grains/Chips: Specifically graded sizes for “Vitrified Tiles,” “Terrazzo Flooring,” and landscaping applications.
- Calcined Dolomite (Dolime): High-reactivity grade used primarily in the steel industry for slag stabilization.
