A superfine-grade paint or ink enquiry needs the actual distribution behind the fineness description. This industrial natural barium sulfate BaSO4 barite is described as white fine powder with stated BaSO4 ≥85.0%, also named for plastic, rubber and powder-coating assessment.
Define the fineness required for the formulation
Request the particle-distribution or sieve report, including its method and material reference. Fine or superfine wording does not establish a mesh fraction or a numerical particle value. Compare the actual results with the grading limits required by the proposed system.
Review colour and composition as separate criteria
Ask for current BaSO4 and relevant impurity results, keeping the content minimum distinct from an exact sample analysis. White appearance is qualitative; obtain an optical report with its test method if numerical whiteness matters to acceptance.
- Physical grade
- Use measured grading and optical results rather than descriptive wording alone.
- Material identity
- Confirm the offered grade in matched technical, analysis and safety documents.
Assess each application with the actual material
Describe the paint or ink formulation and agree representative evaluation criteria. Qualify plastic, rubber and powder-coating roles separately rather than assuming a transferable result. Request density and surface-treatment evidence where those properties matter to the assessment.
Retain the sample reference, conditions and observations with the report set. No verified dispersion, gloss, opacity, loading ratio or universal formulation result is established by the natural-barite name, minimum content or superfine designation alone.
