Tough, high-temperature-generating applications, such as:
Lubrizol® 86GR is the latest generation of calcium sulfonate technology for manufacturing water-resistant greases. As a modified 400 TBN overbased calcium synthetic sulfonate, Lubrizol 86GR converts into a gel in two to three hours, without the addition of other acids or bases. This stable chemistry gels predictably, requiring only the addition of water in a robust procedure, for faster, reproducible batch processing.
Traditional lithium-based greases use a fatty acid (or a diacid for more complex greases), along with a lithium base and additive enhancements to achieve desired performance levels. At high temperatures, such greases can lose their structure, with the oil separating out from the thickener. The temperature at which separation occurs is known as the dropping point.
In contrast, calcium sulfonate greases exhibit a higher dropping point, converting a fluid detergent that incorporates amorphous calcium carbonate, into a grease that contains calcite particles. Such particles have innate lubricity, so in many cases, calcium sulfonate greases eliminate the need for performance additives containing sulfur, phosphorous or zinc. This makes them an ideal solution for food processing applications.
