Keep the 600 Mesh model, material reports and actual paint sample connected throughout qualification. This industrial surface-coated activated calcium carbonate is described as white superfine CaCO3 powder with stated purity ≥98.5%.
Define the system in which the sample will be judged
Explain the particular paint formulation and the properties required for acceptance. Agree representative evaluation conditions and how observations will be compared. The material name alone does not verify dispersion, binder compatibility, finished-film performance or an addition ratio.
Confirm composition and measured particle grading
Request current analysis for the proposed powder, including the impurity results relevant to the formulation. Keep the minimum purity separate from an exact sample composition. Ask for the distribution or sieve report behind the 600 Mesh designation and confirm its method rather than assigning an assumed micron size.
- Treatment identity
- Obtain coating chemistry and treatment evidence; activated wording does not specify an agent or level.
- Other acceptance tests
- Request numerical whiteness, moisture or oil-absorption results where required by the paint brief.
Retain evidence for each application conclusion
Use a consistent sample reference on current technical and safety documents and the trial record. Review the observations against the actual criteria, keeping white appearance distinct from measured optical properties. Plastic, rubber, paper making and building are additional named enquiry areas that need independent formulation or process assessment. A paint qualification cannot establish equivalent results for all of those uses.
