XM-BA45 Natural Barium Sulphate BaSO4 Filler for Paint Trials, 88% Whiteness and pH 7–9

XM-BA45 is an industrial white barium sulphate powder with a natural-material designation for paint-industry filler evaluation. Its 88% whiteness and pH range of 7–9 provide specific criteria, while the actual chemical assay needs confirmation before selecting the offered grade.

Request a committed XM-BA45 assay

Obtain a current product-specific analysis giving the actual BaSO4 requirement and relevant impurity limits. Confirm the natural-material route and proposed grade rather than choosing a purity criterion from a broad filler description or assuming a complete paint specification from the chemical name.

Separate sieve residue from particle distribution

The residue entry is 0.01% on a 325 mesh sieve, with the applicable method to be agreed. Request the numerical size criterion with its explicit unit and measured distribution before using D97 in a comparison; sieve residue does not establish a median or complete powder-size curve.

Optical comparison

Use the 88% whiteness with an agreed measurement method and reference for the paint project.

pH comparison

Confirm the preparation and procedure used to assess the 7–9 range.

Grade documents

Request current composition and safety information, plus any applicable certificate with the relevant holder and scope.

Define acceptance in the actual paint binder

Identify the filler role, processing route and film or application tests proposed for the XM-BA45 trial. A natural sulfate description does not establish hiding, compatibility or a finished-paint advantage, so the representative formulation should determine the actual process and appearance result.

For XM-BA45, combine a confirmed chemical assay and powder specification with the optical and pH criteria before sample approval. The actual binder comparison and relevant product documents should establish whether the proposed filler meets the project's requirements.
