Diamond Suspensions and Paste

MetaDi diamond suspensions and pastes are high-quality monocrystalline and polycrystalline diamond polishing products that provide repeatable performance and deliver exceptional sample quality.

Buehler's MetaDi diamond suspension polishing and paste products are tightly controlled to prevent any deviations in particle size or concentrations. This ensures reproducible polishing results and a high quality surface finish for every sample processed.

Color coded diamond suspensions and pastes based on the micron size helps prevent cross contamination on polishing surfaces.

Some materials are not compatible with traditional water-based suspensions due to water-sensitivity or diamond embedding. The Oil-Based MetaDi Monocrystalline diamond suspension as well as MetaDi diamond pastes offer multiple options when working with water-sensitive materials.

Consistent, Repeatable Polishing Results:

Buehler's MetaDi diamond products are tightly controlled to prevent any deviations in particle size or concentrations. This ensures reproducible polishing results and a high quality surface finish for every sample processed.

Fast Preparation Time:

MetaDi Supreme Suspension offers a high material removal rate and minimal deformation making it the product of choice for most materials. The high concentration of polycrystalline diamonds offers numerous sharp cutting faces to efficiently remove material and polish the surface.

Simple Product Recognition:

Color coded suspensions and pastes based on the micron size helps prevent cross contamination on polishing surfaces.

Processing Unique Materials:

Some materials are not compatible with traditional water-based suspensions due to water-sensitivity or diamond embedding. The Oil-Based MetaDi Monocrystalline Suspension as well as MetaDi pastes offer multiple options when working with water-sensitive materials.
For soft materials where embedding is a concern, there are multiple pastes with different concentration levels to choose from.
