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
Abrasive paste is used to achieve high precision and fine surface finishes on metal and other hard materials. It can be used for polishing, lapping, and honing to create smooth and accurate surfaces. It helps in improving the surface quality by removing scratches, blemishes, and other imperfections. This is particularly important in applications where surface appearance and texture are critical. Abrasive paste can effectively remove material from surfaces, making it useful for tasks like deburring, edge rounding, and correcting surface irregularities.
The use of abrasive paste allows for controlled abrasion, ensuring that material removal is consistent and uniform. This is essential for maintaining dimensional accuracy and achieving desired tolerances. By maintaining sharp cutting edges and reducing wear on tools, abrasive pastes can extend the life of cutting tools and machinery, leading to cost savings in the long run. Abrasive pastes are formulated to be compatible with a variety of materials including metals, ceramics, glass, and composites, making them suitable for diverse industrial applications. Abrasive pastes can enhance the efficiency of finishing processes by reducing the time and effort required to achieve the desired surface quality, thus increasing overall productivity.
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.
