GradeSilica Oxide Micro Fine -400TypeSilica Quartz
Greensand-Silica is named as a silica-quartz material for surface-coating enquiries. Before considering a formulation trial, confirm the actual chemical grade and supplied physical form so the discussion concerns a defined material rather than a broad silica name.
Request the complete oxide analysis together
Obtain a product-matched chemical report with a clear reporting basis for SiO2 and the relevant oxides. Ask for the analytical methods and the proposed sample identifier. A complete report is needed to judge the chemical specification; a general purity description does not replace that evidence.
Resolve the physical offer before selecting a sample
Confirm whether the proposed material is sand, another granular fraction or a fine powder. Request its sieve or particle-distribution report and clarify the intended grade designation. A grade suffix should not be treated as a measured size, and a material name does not establish a particular surface treatment.
- Chemical acceptance
- Define the oxide and impurity criteria required by the coating project.
- Physical acceptance
- Define supplied form, particle method and the relevant grain limits.
Link the coating assessment to the confirmed grade
Review matched technical and safety documents before arranging a representative evaluation in the intended binder. No verified silica assay, fine-particle specification or finished-coating benefit is established here. Keep the confirmed material identity and reports with the formulation requirements so a later sample or repeat enquiry can be matched to the actual grade assessed.
