A matting-filler enquiry starts with the surface you want to achieve. This industrial barium sulfate is a white powder with a stated purity range of 90%-96%, offered under the selectable model names NA4387 and NA4388 for formulation assessment.
NA4387 or NA4388: define the finish first
Both model names identify a choice, but choosing between them requires their individual technical specifications. Describe the intended paint, coating, plastic or rubber system and the appearance you are trying to obtain. Ask for representative samples tied to those model names before making a direct comparison.
- For a coating enquiry
- Identify the binder and the required surface finish.
- For a plastic or rubber enquiry
- Identify the polymer and the compound property being evaluated.
Keep matting performance measurable
Matting describes the intended role rather than a guaranteed reduction in gloss. Agree how gloss, colour and surface uniformity will be judged in your formulation. A white powder appearance alone does not provide a numerical whiteness result, and particle measurements are needed to assess any fineness requirement.
Build a model-specific sample request
Request the proposed model's assay, particle distribution and relevant test methods alongside its technical sheet and safety information. Clarify how the stated purity range relates to that individual material. Use the same evaluation conditions for both candidates so any observed difference can be traced to the tested powder and formulation, then confirm the selected specification before a repeat order.
