TypeCalcium Carbonate
The actual 2500 mesh option identifies this heavy calcium carbonate for paint and coating additive assessment. It is described as industrial white powder with stated purity of 96%, with optical and absorption requirements to be defined for the intended formulation.
Set two independent measurement requests
Ask for a whiteness result and its method, and request oil absorption with the test medium, units and procedure. These reports answer different material questions. No verified high-whiteness threshold or low-absorption limit is established by the powder's general description.
- Optical report
- Connect the measured value and test conditions to the proposed grade.
- Absorption report
- Keep the medium, method and endpoint with the reported result.
Connect 2500 mesh with particle and surface evidence
Obtain the sieve standard and particle-distribution report for the actual material. Confirm whether a surface treatment is applied and request its relevant scope. The mesh designation should remain a grade reference until its measurement basis is understood; it does not establish a particular percentile or dispersion response.
Judge the additive in the coating system
Describe the binder and finished-coating acceptance criteria before assessing a representative sample. Review matched technical and safety information and the current assay, then record the material and trial conditions with the results. No universal binder-demand reduction, addition ratio or coating improvement is established here. Use the evaluated powder specification and methods in a repeat enquiry so the technical discussion remains tied to the formulation actually examined.
