FINE WOLLASTONITE POWDER FOR SURFACE PERFORMANCE

Controlled particle size. High whiteness. Industrial versatility.

We supply fine wollastonite grades from 80 to 400 mesh — optimized for ceramics, paints, plastics, construction, and more.

InduMinerals offers fine-grade wollastonite powders in: – Mesh sizes: 80, 150, 200, 325, 400 – Applications: ceramics, coatings, plastics, construction, metallurgy, adhesives Key features: – High whiteness and brightness – Consistent composition and purity – Tight particle size distribution Each mesh size is suited to different use cases: – Coarser grades for structural and cement-based use – Finer grades for paints, plastics, and high-dispersion formulations

TYPICAL APPLICATIONS & BENEFITS

CERAMICS →

  • Used in tiles, sanitaryware, and tableware

  • Enhances green strength and sintering uniformity

  • Reduces warping, cracking, and firing temperature

CONSTRUCTION →

  • Mesh 80–200 used in dry mixes, adhesives, grouts, and fiber cement

  • Improves rheology, shrinkage resistance, and workability

  • Excellent for boards, fillers, and white cement systems

PAINTS AND COATINGS →

  • Mesh 325 and 400 provide film strength, matting, and anti-corrosion benefits

  • Improves scrub resistance and surface finish

  • Low oil absorption aids in formulation efficiency

METALLURGY →

  • Used as a flux extender or filler in steel ladle or casting slag systems

  • Supports slag fluidity and calcium input

  • High purity, non-toxic, and stable at high temperatures

​​

PLASTICS AND POLYMERS →

  • Acts as a cost-effective functional filler

  • Enhances dimensional stability and thermal resistance

  • Mesh 325 improves dispersion in thermoplastics and thermosets
