Specify the paint system when enquiring about this 3000 Mesh activated calcium carbonate. The industrial CaCO3 is described as surface-coated white superfine powder with stated purity ≥98.5%, and the model needs assessment in the intended formulation.
Define the coating requirements before comparing powders
Explain the binder system and the properties used to accept a candidate. Agree representative conditions for evaluating the actual sample. A surface-coated designation does not by itself establish compatibility, dispersion or a finished-paint result.
Request the treatment and particle evidence together
Ask for the coating chemistry and treatment information associated with the proposed 3000 Mesh grade. Obtain a measured distribution or sieve report and its method rather than treating the model as an exact micron specification.
- Confirm the minimum purity with current composition and relevant impurity analysis.
- Request numerical whiteness when optical acceptance requires it.
- Clarify moisture, oil absorption or other physical tests relevant to the paint brief.
Keep each application conclusion tied to the sample
Retain the grade reference with current technical and safety reports and compare the trial observations with the agreed criteria. Activated wording does not identify an agent or treatment level, and no universal addition ratio follows from the material name. Plastic, rubber, paper making and building are additional named enquiry areas that require their own formulation or process assessments, rather than an assumption that paint results transfer unchanged.
