Diamond Polishing Compound (Diamond Paste) – 5 / 10 / 20 grams

Diamond polishing compound, also known as diamond paste or diamond lapping compound, is used in precision finishing processes where conventional abrasives are not effective.

The paste contains microscopic diamond particles suspended in a lubricant carrier. When applied to a polishing tool or lap, these diamond particles remove microscopic amounts of material, gradually reducing surface roughness and producing a highly refined finish.

Because diamond is the hardest known material, diamond compounds are ideal for polishing extremely hard surfaces including:

Diamond paste is widely used in mould tool and die polishing, where achieving extremely smooth surfaces is essential for part release, surface finish and mould performance.

1. Apply a small amount of diamond compound to the polishing tool or lap.

2. Apply lapping fluid or extender lubricant if required.

3. Begin polishing using a felt bob, wooden lap or polishing cloth.

4. Work progressively through finer micron grades to achieve the desired finish.

• General-purpose polishing

• Light material removal

• Precision finishing work

• Improved heat management

• 25–45 micron – surface preparation / stock removal

• 16–10 micron – pre-polish

• 6 micron – refinement

• 3 micron – mirror finishing

• 1–1/10 micron – optical finishing

For best polishing performance, Moleroda recommend using lapping fluid alongside diamond compound.

Lapping fluid helps:

Using lubrication during polishing also improves the lifespan of both the abrasive compound and polishing tools.
