Lubricating fluid

for metal parts

Product overview
The diamond suspension polishing fluid is formulated in a temperature-controlled laboratory by homogenizing high-performance diamond abrasives with cooling and lubricating additives. Available in water- and alcohol-based variants, the system provides a stable suspension and is free of volatile organic compounds. It is intended for metallographic and petrographic sample preparation and for high-precision grinding and polishing of ferrous and non-ferrous metals, ceramics, composites, gemstones, precision instruments and optical glass.

Product advantages

• High particle-size concentration: selected diamond abrasives with strict purification and grading ensure a narrow and consistent particle-size distribution.
• Stable suspension system: water- and alcohol-based formulations keep diamond particles uniformly suspended for consistent polishing performance.
• High removal and polishing rates: high-hardness abrasives provide efficient material removal, reducing abrasive consumption and process time.
• No volatile organic compounds: modern wetting and dispersing agents with no VOCs, improving operator safety and environmental compliance.
