Complex greases have certain advantages over their mono-soap counter parts, including:
- Higher dropping point
- Better water resistance
- In some cases, higher load bearing capability
This makes them the ideal upgrade for applications where their mono-soap counterparts are being pushed beyond their limits.
Manufacturing complex greases generally have one thing in common; the “two-hour hold”. The batch is held at a constant temperature, usually lower than the saponification temperature of a mono-soap grease, for a minimum of two hours while the complexing takes place. After that, the batch is heated up to a higher peak temperature to evaporate off volatile undesirables and to achieve the right texture.
We have experience of manufacturing:
- Lithium Complex
- Aluminium Complex Grease
- Calcium Sulphonate Complex Grease
If you are wanting to make these, we can offer a raw materials sourcing, formulations and process protocols. In addition we can undertake the following, to get your formulation to a level where it can be scaled up:
- Making trial batches
- Liaise with raw material suppliers and accredited testing laboratories
