For a paint enquiry, identify the particular PCC grade before comparing formulation results. This precipitated calcium carbonate is described as industrial white superfine powder, also called light calcium carbonate, with stated purity 96% and formula CaCO3.
Compare the actual grade options with their reports
Premium product and standard product are the available model choices. Request the technical and analysis documents for the choice under consideration; the names alone do not establish different purity, particle sizes or treatment. Keep the selected grade reference with the sample throughout assessment.
Define the particle and optical measurements
Superfine describes the powder qualitatively without specifying a numerical distribution or mesh. Ask for the measured size data and method relevant to the paint brief. Obtain a separate optical result if numerical whiteness is an acceptance requirement.
- Match the reported 96% purity to the proposed grade and current analysis.
- Confirm any surface treatment, moisture or oil-absorption requirement using its own test evidence.
- Record the formulation and agreed assessment conditions before comparing samples.
Evaluate paint behaviour in the intended system
Representative trials are needed to assess dispersion and the finished coating against the buyer's criteria. Neither the PCC name nor the superfine description establishes coverage, gloss or an addition ratio. Plastic, rubber, paper making and building are also named enquiry areas, and each needs its own application qualification. Do not carry a paint trial conclusion into those uses without evidence.
