Matte Barium Sulfate names the selectable grade for this industrial filler enquiry. The BaSO4 powder has a stated purity range of 85%-88%, with paints, powder coatings and plastic fillers among its intended applications and rubber also within the enquiry scope.
Distinguish the powder from the finished surface
The material is a barium sulfate powder for formulation assessment. A matt finish describes the surface you want the complete system to produce; it does not specify a numerical gloss reduction from the raw mineral alone. Set a measurable finish target before deciding whether a sample meets your needs.
Which formulation is being evaluated?
A powder-coating enquiry should identify the coating system and the relevant film criteria. A plastic or rubber enquiry should identify the polymer compound and the property being assessed. Keep those briefs separate so the same application wording does not become an assumption of universal suitability.
- Define the formulation and intended surface appearance.
- Request the grade's particle distribution and assay method.
- Evaluate a representative sample against agreed criteria.
Specify the matte-grade evidence
Ask for the technical sheet and safety information associated with the Matte Barium Sulfate choice. Confirm the full particle distribution, rather than inferring a size from the grade name, and clarify how the stated assay range applies to the proposed supply. Appropriate addition levels and processing conditions need formulation-specific assessment; no universal dosage or finished-coating result is established here.
