Paint-extender substitution should be evaluated through the finished formulation. This pure white barium sulfate barite powder has a selectable whiteness range of 98.5–99%, stated BaSO4 content of 98–99% and moisture content of 0.03% maximum. Paint is a named application for sample evaluation.
Specify the actual whiteness option in the trial brief
The selectable range is 98.5–99%, while the parameter table also gives a whiteness value of 99%. Identify the required acceptance range and confirm the test method for the sample. Powder whiteness must remain distinct from the colour or covering result of the completed paint.
Resolve crystal size before using it as a powder limit
A largest-crystal dimension of 1.6 mm is stated. Ask how that measurement is defined and request the complete powder particle distribution before applying it to a formulation specification. It should not be interpreted as D50 or as an established finished-powder size limit without further evidence.
Measure substitution against the paint's own criteria
Describe the existing extender, proposed comparison and properties that must remain acceptable. Test the barite candidate in the intended binder and assess the resulting processing and film properties. A broad replacement description does not establish a universal loading, full substitution or a guaranteed reduction in material cost.
Complete the sample evidence
Request current composition and moisture analysis alongside the agreed whiteness method. Coating, plastic and rubber enquiries require their own relevant trials. Keep the sample identity, test conditions and acceptance results together when deciding whether this powder meets the project requirement.
