A white raw powder and a transparent finished paint answer different optical questions. This natural industrial barium sulphate has 96% minimum purity, a 3μm D50 and a 9μm D97 for paint-material evaluation, with the intended binder deciding the relevant trial.
Start with the natural paint-powder profile
Use both particle percentiles when comparing this BaSO4 with the existing filler specification. Request the full distribution, measurement method and any treatment information before linking those raw-material values to dispersion or finish.
Keep the minimum whiteness in context
The powder has an 88% minimum whiteness value and a pH range of 7–7.5. Confirm the methods and the paint's own acceptance criteria, rather than treating a white appearance as proof that the finished formulation will meet a transparency target.
- Material specification
- Identify the natural grade by its 96% minimum assay and measured 3μm/9μm particle profile.
- Optical specification
- Agree the binder and test conditions that will determine the paint result.
Resolve the remaining measurement questions
Ask for the unit and basis used for water-soluble matter, alongside the current chemical analysis. These details help make the paint-powder comparison precise without inventing a limit or assuming that a broad multifunctional label establishes performance.
Describe the intended paint project and the actual powder requirements in the enquiry. A confirmed natural BaSO4 specification and a relevant optical trial provide a useful selection route without an assumed transparency guarantee.
