Track the proposed powder from treatment identification through particle grading to paint assessment. This industrial surface-coated activated calcium carbonate is described as white superfine CaCO3 powder with stated purity ≥98.5% and a 2800 Mesh model designation.
Identify the treatment being proposed
Request the coating chemistry and the relevant treatment evidence for the actual grade. Activated and surface-coated do not establish an agent, treatment level or compatibility with every coating binder. Ask which current report set identifies the sample under consideration.
Connect measured grading to the same material reference
Obtain the particle distribution or sieve report with its method for the 2800 Mesh model. The designation should not be converted into an assumed exact micron size. Confirm the minimum purity and relevant impurities independently in current analysis.
- Optical requirement
- Request numerical whiteness with its method if the paint brief requires it.
- Other material questions
- Obtain moisture, oil-absorption or other physical evidence needed for acceptance.
Judge paint suitability through representative results
Describe the particular formulation and agree the criteria and conditions used to assess the proposed sample. No dispersion guarantee, finished-coating property or universal addition ratio follows from the treatment and mesh names. Keep current technical and safety documents with the material reference and observations. Plastic, rubber, paper making and building are further named enquiry areas, each requiring evidence relevant to its own system rather than a transferred paint conclusion.
