Arrange the paint enquiry around the sample, its grading and its treatment before assessing formulation behaviour. This industrial surface-coated activated calcium carbonate is described as white superfine CaCO3 powder with stated purity ≥98.5% and an 800 Mesh model designation.
Identify which sample the reports characterize
Request current composition and impurity analysis for the proposed grade. Confirm the reporting basis for the minimum purity and use a consistent sample reference across the technical and safety documents. The chemical threshold is one acceptance criterion rather than a complete paint specification.
Request measurable grading and treatment information
Ask for the distribution or sieve results behind the 800 Mesh designation and the measurement method. A model name does not establish an exact micron distribution. Obtain the coating chemistry and treatment evidence independently from the particle report.
- Meaning of activated
- The designation does not itself establish an agent, treatment level or binder compatibility.
- Optical and other tests
- Request numerical whiteness, moisture or oil absorption where the paint brief requires them.
Judge the grade using the actual coating criteria
Describe the particular formulation and agree representative evaluation conditions for the sample. No verified dispersion, finished-film property or addition ratio follows from the treatment and mesh labels alone. Plastic, rubber, paper making and building are further named assessment areas and need their own application evidence. Retain the material reference and current documents with the observations so each conclusion remains tied to the use tested.
