Chemical purity and powder whiteness answer different questions when screening a paint material. This industrial white barium sulfate has a 98% minimum purity and a 98.8% whiteness value for coating and paint evaluation, with the actual formulation deciding suitability.
Agree the assay that governs acceptance
Request a current analysis identifying the guaranteed minimum and the reported content on a clear basis. Confirm how the 98.6% content description relates to the 98% minimum before treating either label as the final purchase specification.
Define what the whiteness result means
Ask for the whiteness method and the measurement conditions used for the offered powder. The 98.8% value gives an optical comparison point, but it does not determine opacity, gloss or the colour of every finished paint system.
What else should the powder report include?
Obtain the unit and method for D50, along with any relevant treatment information. These details allow a meaningful particle comparison without assigning an unstated unit to the numerical particle entry.
Keep the approval tied to the intended use
Evaluate the material in the actual coating binder and agree the results that will decide acceptance. Agriculture or electronics enquiries require their own grade requirements and qualification evidence rather than relying on a broad industrial material description.
Send the assay limits, optical criteria and binder brief together when requesting technical information. This makes the white powder enquiry specific while keeping measured raw-material properties separate from untested formulation performance.
