TypeBarium Sulfate
A leather-coating or printing-ink enquiry needs a defined appearance target. This industrial barium sulfate white powder is intended for matting-filler assessment in inks, plastics and coatings, with the exact particle and finish specification to be confirmed for the proposed grade.
Read the assay ceiling carefully
The stated purity is ≤85%, meaning no more than 85%; it is not an 85% minimum. Request the offered grade's complete assay specification and the method used to determine it. This clarification matters when your formulation requires a particular composition rather than a broad powder description.
Connect the powder to the intended surface
For printing inks, identify the ink system and the appearance being evaluated. For leather coatings, describe the coating formulation and the desired surface finish; for plastics, identify the polymer and compound target. These are separate assessment briefs, and a result in one system should not be assumed to transfer unchanged to another.
Useful trial questions
How will the powder disperse under the chosen preparation conditions? What surface appearance will count as acceptable, and how will it be measured? Agree those questions before testing a representative sample.
Request the particle evidence behind a matting enquiry
Matting is the intended role, while a numerical gloss change and a measured particle size remain unconfirmed. Ask for a particle report with its method, the technical sheet and safety information for the same grade. Record the sample identity and evaluation conditions so an accepted result can support a clear repeat specification.
