An explicitly measured median helps make a precipitated barium sulfate comparison precise. This industrial white powder has 98% minimum purity, D50 at 0.5μm and 98.5% whiteness for coating and paint evaluation, with the actual binder deciding suitability.
Use the 0.5μm median as one comparison point
Match the D50 with the current coating-filler requirement and request the complete particle distribution. Confirm the test method before linking that median to dispersion or film quality, because one percentile does not describe the entire powder population.
Compare assay and whiteness on defined methods
Request current chemical analysis and the method behind the 98.5% whiteness value. Keep the 98% minimum assay distinct from optical performance; purity and powder colour do not determine finished-film opacity or gloss on their own.
- Raw-material enquiry
- Confirm the supplied grade, measurements and any surface treatment.
- Paint-system enquiry
- Agree the binder and the trial criteria relevant to the intended finish.
Approve the actual application rather than a broad label
Evaluate the powder in the intended coating system using its own acceptance tests. Agriculture or electronics requirements need separate grade specifications and qualification evidence, without industrial paint use becoming an assumed approval for another application.
Bring the assay, median, whiteness method and binder brief together in the technical enquiry. A complete grade report and a relevant formulation trial provide a clear selection route without an invented coating-performance guarantee.
