Confirm the chemical acceptance criteria for this 1250 Mesh powder before assessing its formulation behaviour. The material is industrial surface-coated activated calcium carbonate CaCO3, described as white superfine powder with stated purity ≥98.5%.
Request composition evidence for the candidate sample
Ask for current analysis and the impurity results relevant to the paint requirements. Keep the minimum purity distinct from the exact composition of the proposed sample. Use the same material reference on the technical, analysis and safety documents.
Assess treatment identity alongside measured grading
Request the coating chemistry and treatment evidence for the grade under consideration. A surface-coated or activated name does not identify an agent, treatment level or compatibility with a particular binder.
- Obtain the particle-distribution or sieve report for the 1250 Mesh model.
- Confirm its measurement method rather than converting mesh to assumed microns.
- Request optical, moisture or oil-absorption tests where the paint brief requires them.
Use the formulation trial to judge suitability
Describe the actual coating system and agree representative conditions and acceptance criteria for the proposed powder. No dispersion result, finished-film property or universal addition ratio is established by the chemical and mesh designations alone. Plastic, rubber, paper making and building are additional named assessment areas, each needing its own formulation or process evidence. Retain the sample reference with the observations and current documents so a conclusion applies to the material and use evaluated.
