XM-BA13 is a natural barium sulphate white powder identified for outdoor paint, with minimum BaSO4 content of 96%. Its D50 of 3.3 microns and D97 of 9 microns provide two specific size criteria for a defined coating-material comparison.
Use both particle percentiles in the paint brief
The median and D97 describe different points on the powder's distribution. Confirm the measurement method and actual curve needed by the intended paint process, then assess the proposed mineral in its binder rather than treating either size value as a finished-film result.
Agree optical and absorption acceptance separately
The whiteness requirement is at least 88%, with an oil-absorption range of 13–15 g/100g. Specify the optical reference and absorption method before comparing grades, since these criteria do not themselves quantify hiding, application behaviour or an outdoor coating's durability.
- Composition
- Confirm the minimum 96% content, relevant impurity limits and natural-material route through current grade documents.
- pH
- Use the 7–9 range with an agreed preparation and measurement method.
- Physical-test basis
- The specific-gravity entry carries 4.40 g/cm3; confirm its method and the actual moisture limit applicable to the offered grade.
Qualify the sulfate in the outdoor coating system
Define the actual paint binder, processing route and appearance requirements for the XM-BA13 trial. Any outdoor-performance target needs evidence from the relevant coating system rather than an assumed weathering benefit from the natural mineral or industrial-grade description.
For this XM-BA13 comparison, combine the confirmed assay and particle criteria with the agreed optical and physical methods. A representative binder trial and the project's actual coating tests should establish whether the proposed grade meets the intended outdoor-paint requirements.
