JSYAPG‑OILDIAF oil‑based diamond polishing paste is a viscous polishing compound with classified synthetic diamond powder uniformly dispersed in high‑viscosity oily carrier matrix. It incorporates oil‑soluble lubricants, anti‑oxidation agents and suspension modifiers. Multiple particle‑size grades are available ranging from coarse to ultra‑fine. This polishing paste is mainly intended for manual hand‑polishing operations. It is widely used for metallographic sample preparation, repair and finish

Product Detail

Product Detail Page: JSYAPG‑OILDIAF diamond polishing paste is produced using carefully screened synthetic diamond grit. The diamond powder goes through particle‑size classification, shape sorting and impurity removal before mixing with the viscous oil‑based binding medium. High‑viscosity oily matrix inhibits rapid settling of dense diamond grains. Formulated lubricating additives reduce frictional heat generated during hand rubbing. Anti‑oxidant components resist thermal degradation caused by continuous friction, so that the paste maintains consistent polishing performance during extended manual working sessions.

Manual polishing is frequently required for mould repair, local finishing of tool edges and metallographic laboratory sample preparation. Conventional loose lapping slurries are difficult to control during hand operations; abrasive tends to run off the working surface, resulting in inconsistent removal effect and low working efficiency. Hard‑alloy and tool‑steel components are susceptible to local over‑heating and surface scorching under intensive friction. Metallographic specimens demand scratch‑free surfaces for accurate microscopic inspection of grain structure.

Thanks to its thick, viscous consistency, this diamond polishing paste adheres firmly onto polishing laps, wooden sticks, cloth laps and polishing pads. It does not readily flow away during hand polishing. A full series of grit grades supports progressive finishing workflow: coarser grades remove tool marks and local defects, medium grit levels perform surface leveling, and ultra‑fine grades deliver mirror‑like final surfaces. It is suitable for workshop manual repair operations as well as laboratory metallographic sample preparation. The oily lubricating film lowers burning risk on hard alloy and tool‑steel edges.

For practical application, select the appropriate grit grade according to the initial surface condition and target finish. Apply a thin layer of polishing paste on the polishing lap. Moderate hand pressure and steady reciprocating or circular motion are recommended during polishing. Clean the workpiece thoroughly with suitable solvent after finishing to eliminate residual oily carrier and fine diamond debris.

Avoid heavy contamination, prolonged high‑temperature storage and direct sunlight. Excessive heat may cause separation of oily base and diamond sedimentation. Once oil‑solid separation cannot be homogenized, the polishing paste loses its intended performance.

Major application fields: metallographic specimen hand polishing in material laboratories, local finishing and repair for precision mould inserts, edge sharpening and mirror polishing for cutting tools, manual surface refinement of cemented hard‑alloy components.

Store the product in tightly‑sealed original containers within 10‑30℃. Keep away from heat sources and direct sunlight. Stir the paste gently before use after long‑term storage.
