Abstract
The present invention relates to a controlled release gel with an ashless component and defined ash-producing component. Further, the invention relates to the use of a controlled release gel with a controlled level of ash-producing (i.e., metal) components for delivery of additives into lubricants wherein the gel has reduced ash and SAPS producing components.
Claims20
A controlled release gel composition comprising ash producing components and ash free components resulting in the production of a controlled release gel that produces reduced components of ash, SAPS (low sulfur, low phosphorous and low ash) and mixtures thereof.
A process for control releasing an additive into a lubricant comprising (1) supplying one or more desired additives to a lubricant;
- and (2) contacting the lubricant with a controlled release gel wherein the gel composition comprises ash producing components and ash-free components resulting in a reduced level of ash produced from using a controlled release gel.
A controlled release gel comprising ash producing components and ash free components used in a lubricating system to improve the prevention of wear and deposit formations in the system and to produce reduced ash and SAPS components.
A use of a controlled release gel in a lubricating system to produce low level of SAPS during use of the system and wherein the gel comprises ash producing components and ash-free components.
