Define the coating acceptance criteria before selecting a heavy calcium carbonate model for paint assessment. The industrial material is described as white superfine CaCO3 powder with stated purity 96%, with several actual mesh choices for comparison.
Choose the model that will be characterized
The choices are 600 Mesh, 800 Mesh, 1250 Mesh, 1500 Mesh, 2500 Mesh, 2800 Mesh and 3000 Mesh. Ask for the distribution or sieve report associated with the proposed model and confirm its method. The range does not define continuous options or an exact micron distribution.
Separate purity, appearance and optical testing
Request current composition and relevant impurity analysis to assess the stated purity. Obtain a numerical whiteness measurement independently when optics form part of acceptance; white appearance is a qualitative description.
- Identify the sample on its technical and analysis documents.
- Request moisture or oil-absorption results where the formulation requires them.
- Confirm any treatment separately rather than assuming it from the heavy designation.
Compare actual results against the paint brief
Describe the formulation and agree representative evaluation conditions. Heavy does not establish a production route or density value, and the chemical name does not verify dispersion, coverage, gloss or an addition ratio. Plastic, rubber, paper making and building are additional named enquiry areas that need independent assessment. Retain current safety information with the sample reference and observations so each conclusion remains specific to the powder and system evaluated.
