Typical triaryl phosphate additive concentrations vary from 0.5% to 3.0%, depending on formulation complexity. Usually 0.5-1.5% provides acceptable performance in relatively simple systems with petroleum and synthetic base stocks. More complex formulations, where several components might interact with metal surfaces, may require adjustment of several
components or an increase in the phosphate concentration to 2-3%. These higher levels are usually needed if controlled seal swell is desired. In some synthetic base stocks, the solvent power of phosphate esters can be used to significant advantage. Levels of phosphate up to 5% or more can function as an aid in dissolving other additives having only limited
solubility in the base oil.
Performance advantages:
A fluids and lubricants formulator will find that the physical and chemical properties of phosphate esters make them easy to work with:

• Triaryl phosphates exhibit excellent solubility in mineral oil and synthetic base fluids, including more difficult base fluids such as polyalphaolefins (PAOs) and silicones.
• Phosphate esters are desirable for use in high performance fluids as they contain no metals or chlorine, and do not darken the finished fluid.
• Phosphate esters are easy to pump, mix and store at ambient temperatures.
• Phosphate esters can show multi functional capabilities in providing a controlled amount of seal swell, and in some systems, metal surface passivation.
• Phosphate esters low odor, low volatility and low skin irritation minimize handling and blending concerns.
• Phosphate esters contain no metallic elements, and thus contribute no ash to the formulation.

Additin RC® 3662 clearly demonstrates the ability to reduce friction and wear in industry standard tests. The excellent performance identified in the four-ball test results table predicts extended equipment life and reduced energy consumption. Under severe load conditions, a combination of antiwear and extreme pressure additives is required to protect surfaces in full sliding contact. Phosphate esters are considered mild extreme pressure additives and can be used to improve the performance of other phosphorus, sulfur, or chlorine extreme pressure additives. Triaryl phosphates are not as active as many sulfurized or chlorinated EP additives but they offer the advantage of being non-corrosive and non-staining to most metals. In cutting and grinding fluids, the polishing action of triaryl phosphates results in an excellent surface finish. The machined product exhibits a reduced tendency to rust compared with products machined with lubricants containing more corrosive sulfur- and chlorine-containing additives. High performance lubricant additives ought not reduce the stability or operating range of base fluids. Triaryl phosphates exhibit thermal and oxidative stability that is superior to most base oils, resulting in extended fluid life.
