Abrasive Lapping Paste
The Kemet range of specially formulated Lapping Compounds (White Aluminium Oxide and Silicon Carbide) have many applications but are particularly suited for the lapping of mechanical seals, valve seats and valve grinding as they retain texture and lubrication during extended lapping operations.
The main advantages include:
- Easy to clean - Water soluble
- Not petroleum based - environmentally friendly
- Fast & Effective Cutting
- Good Lubricity
- Strictly manufactured in house to ISO 9001:2015 Quality standards
- Only finely graded abrasives used
Silicon Carbide Lapping Paste
The preferred abrasive for fast cutting of all but the hardest and toughest metals. It will produce a smooth flat surface, but not a polished one.
