Moisture, median particle size and colour give this barite paint powder several distinct comparison points. The grade has 98.5% BaSO4 content, 0.2% moisture and a D50 of 0.7μm, with an actual whiteness option of 98.5–99%.
Keep the particle terms distinct
Use the explicit D50 value when comparing the median particle requirement. Request a definition for the separate 2.5μm Largest Crystal measurement, because a crystal-size description does not automatically represent a D97 particle percentile.
Confirm the offered colour and chemistry
Ask for the method supporting the 98.5–99% whiteness option and the current assay reporting basis. The pH range is 7–9; confirm its test conditions alongside the chemical analysis before using it as an acceptance criterion.
- Moisture question
- Which measurement method and current result apply to the offered paint grade?
- Oil-demand question
- What unit and method define oil absorption for the material?
Build the paint trial around documented properties
Obtain any surface treatment information and the applicable RoHS documents if compliance is part of the purchase requirement. Then test the powder in the intended binder, using the paint system's own dispersion and optical acceptance criteria.
Include the content, moisture, particle requirement and actual whiteness option in the technical enquiry. A defined measurement set and a matched paint trial make the comparison useful without assuming a permanent optical effect or an undocumented compliance guarantee.
