Performance Highlights
  • Additin RC® 3661 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.
