Paint-formulation comparison needs chemical, particle and optical evidence for the powder actually under consideration. This industrial heavy calcium carbonate is described as white superfine CaCO3 powder with purity 96% and an activated designation.
State the optical requirement before comparing whiteness
Identify which optical measurement the formulation requires and ask for its method and reporting scale. White appearance and a high-whiteness description do not provide a measured optical result or demonstrate performance in a coating.
Review particle measurements for the named mesh grade
The actual models are 600, 800, 1250, 1500, 2500, 2800 and 3000 Mesh. Specify the option being considered and obtain measured distribution data, because these labels do not establish D50, D97 or dispersion behaviour.
- Define the paint project’s chemical, particle and optical criteria.
- Review the selected mesh model’s current measurements.
- Assess relevant formulation-trial observations against the same criteria.
Clarify treatment before interpreting formulation results
Ask whether the offered powder has surface treatment and request documentation of its actual nature where applicable. An activated name alone does not establish treatment chemistry or explain a coating result, so compare evidence linked to the sample tested.
Plastics, rubber, papermaking and building materials are additional listed application directions and need separate use-specific assessments. Obtain current safety information and retain the actual mesh, analytical results and coating observations together, allowing measured grade data and the intended formulation to guide the final material choice.
