A paired particle report and moisture value give this barite paint-powder enquiry a defined physical starting point. The powder has D50 at 8μm, D97 at 30μm and 0.3% moisture, with an actual whiteness option of 86–88%.
Confirm the chemical grade before approval
Request a current BaSO4 assay and accepted limits on one clear reporting basis. Review the accompanying oxide analysis with the actual grade documents, rather than treating a broad content description as the complete chemical specification.
Use the two particle percentiles consistently
Compare both D50 and D97 with the intended paint-filler requirement and confirm the measurement method. Ask how the separate 50μm Largest Crystal criterion is defined, keeping that description distinct from the measured percentiles and the full particle distribution.
- Colour and moisture
- Confirm the methods behind the actual whiteness option and 0.3% moisture value.
- Acidity requirement
- Request the current pH method and tolerance for the offered grade.
Connect the powder report to the paint system
Obtain any treatment information and identify the actual industrial-paint or powder-coating binder. Agree the dispersion and optical tests that will determine acceptance instead of inferring a finish benefit from raw-powder whiteness.
Include the chemical limits and both particle requirements in the technical enquiry. Confirm which current technical report applies to the offered powder. A confirmed assay and a relevant binder trial make the barite comparison useful without an assumed density or coating-performance guarantee.
