A coating-material comparison needs more than the name barium sulfate. This natural industrial barite powder gives a D97 of 13.3 microns and a whiteness range of 86–94%, with paint, powder coating and plastic uses identified for formulation evaluation.
Frame the coating trial around acceptance limits
For this barite grade, define which coating properties the raw material must satisfy before approving a sample. The powder form and industrial classification identify the material category, while a formulation trial is needed to establish the result in the selected binder and processing route.
Distinguish range values from batch targets
The 86–94% whiteness range gives the buyer a selection question rather than one universal colour result. Ask which whiteness target will apply to the supplied barite and use the same measurement reference when comparing the material with another coating ingredient.
- Set a barite whiteness acceptance limit within the stated range.
- Request the distribution report corresponding to the 13.3 micron D97 criterion.
- Confirm the BaSO4 assay, identity and analysis methods in the product-specific specification.
Check the option against the end use
The model option is named Drilling Barium, while this powder is presented for industrial coating work. Specify the actual coating, paint or plastic application in the enquiry; the option name is not evidence of a drilling-fluid capability or a guarantee of performance in another process.
The pH value of 7±0.5 offers an additional criterion for technical comparison, provided the test method is agreed. For this natural sulfate, a useful qualification package ties the required whiteness, particle distribution and composition to a representative sample for the intended coating system.
