AI Overview
Marine protection paint grade
dolomite powder (CaMg()
) is a high-purity (97.5%–99%+), white mineral filler used to enhance durability, weather resistance, and cost-effectiveness in marine coatings. It provides superior resistance to UV, moisture, and corrosion, acting as an extender pigment that improves coating longevity, viscosity, and prevents peeling.
Key Specifications for Marine Grade
- Purity & Composition: High-purity with 50-60% and 35-45%.
- Whiteness: High whiteness (90%–98%) is essential for consistent color.
- Particle Size (Mesh): Typically 300 to 500 mesh (or 5 to 100 microns) for smooth, consistent application.
- Moisture Content: Low moisture, typically , to prevent paint defects.
- pH Value: 8.5–9.5 for optimal binder compatibility.
Benefits in Marine Applications
- Enhanced Durability: Increases resistance to abrasion and cracking.
- Corrosion Resistance: Acid/alkali resistance protects against harsh marine environments.
- Improved Structural Integrity: Reduces blistering and water ingress.
- Cost Efficiency: Provides a low-cost, high-performance filler alternative.
- Surface Modification: Often surface-treated (e.g., with silica or stearic acid) to further improve hydrophobic properties in water-exposed environments.
