A paint formulation may need optical measurements that a general powder description cannot supply. This heavy superfine activated calcium carbonate is white industrial CaCO3 powder with stated purity of 96%, available through several mesh models.
Set an optical target for the coating trial
Explain the colour and finish criteria that will decide whether the sample is acceptable. Request the whiteness result together with its method so that the comparison uses a defined measurement rather than white appearance alone.
If gloss or opacity matters, include those measurements in the actual paint evaluation. They are formulation outcomes and cannot be concluded from the carbonate name or purity figure.
Choose mesh with a model-specific particle report
The actual model choices are 600, 800, 1250, 1500, 2500, 2800 and 3000 Mesh. Confirm which label is being offered and ask for the corresponding particle distribution and test procedure.
Review moisture and oil absorption where they form part of the buyer’s acceptance criteria. Keep these physical properties separate from the 96% composition statement, which does not define the complete behaviour of the powder.
Confirm treatment scope before formulation approval
The activated designation calls for a declaration of the actual surface-treatment scope. It does not identify a treatment chemical, its amount or a guaranteed compatibility result in a selected binder.
Plastic, rubber, papermaking and building are also named uses, each requiring a relevant evaluation. For the paint enquiry, retain the current technical sheet and batch analysis with the sample-trial report so that the decision refers to the specific offered model.
