Transparency is a result to measure in the intended coating system. XM-PB02 is an industrial white precipitated barium sulfate powder with 98% purity and pH 7–9 for that material enquiry, with the actual powder specification still needing definition.
Put a unit behind the PB02 particle requirement
Request a unit-defined D50 and the full particle distribution with its measurement method. A descriptive nano or ultrafine label does not establish a size in nanometres, and an undefined median should not be converted to a nanoscale value by assumption.
Define the optical and oil measurements
Ask for the whiteness scale and method, oil-absorption units and any surface treatment information. Those definitions allow a meaningful powder comparison before an optical result is attributed to the offered precipitated grade.
- Confirm current assay and the complete powder specification.
- Identify the actual coating binder and transparency criteria.
- Evaluate the material against those criteria in a relevant trial.
Keep other applications tied to their own evidence
Paint, printing, enamel and plastics projects should use the requirements of their actual formulations. Battery enquiries need separate chemistry and qualification evidence, and any ISO requirement needs applicable documentation with a clear scope.
Include the model and intended clarity target with the requested grade reports. A measured binder trial connects the 98% powder to a real selection decision without an assumed nanoscale, transparency or compatibility guarantee.
