Assess the coating as well as the particle grade when considering this activated calcium carbonate for paint. The industrial CaCO3 is described as surface-coated white superfine powder with purity ≥98.5% and an actual 2800 Mesh model designation.
Identify what the surface treatment involves
Request the coating chemistry and treatment evidence for the proposed grade. Surface-coated and activated identify the material designation, but do not establish an agent, treatment level or compatibility with a particular paint binder. Relate the requested information to the intended formulation.
Check how the 2800 Mesh grade is characterized
Ask for the particle-distribution or sieve report and the method behind the model designation. Do not convert the mesh label into an assumed micron distribution or a guarantee that all particles meet one size. Confirm the minimum purity using a current analysis and relevant impurity results.
Add optical evidence where acceptance requires it
White appearance is distinct from numerical whiteness. Request an optical measurement, moisture or oil-absorption result where the paint assessment needs that property.
Evaluate the proposed powder against the paint brief
Provide the actual formulation and agree representative conditions for testing the sample. Assess dispersion and finished-coating criteria directly rather than inferring performance from treatment wording. Plastic, rubber, paper making and building are additional named enquiry areas and need independent qualification. Keep the grade reference with current technical and safety reports and the trial observations; no universal loading ratio or finished-product result is established by the name.
