Product Description

DURAD® 220B-EP is a 100% active phosphate ester multifunctional extreme pressure and antiwear additive for lubricants. Triaryl phosphates are widely known as effective, ashless antiwear and mild extreme pressure additives for lubricants and functional fluids.
The primary function of triaryl phosphates is to reduce friction and wear in applications where high loads cause boundary lubrication conditions.
The DURAD® product line offers the broadest range of physical and performance properties tailored for specific applications. The t-butylphenyl phosphates are one of several families of products in the lubricant additives product range. Other additives families include trialkyl phosphates, isopropylphenyl phosphates and cresol- and xylenol phosphates.

Summary of industrial oil performance
• DURAD® 220B-EP displays excellent antiwear and extreme pressure performance in laboratory tests
• Good performance in the FZG gear test
• Excellent protection against steel corrosion
• Good solubility and stability in a wide range of lubricant base stocks

DURAD® phosphate esters clearly demonstrate an ability to reduce friction and wear in industry standard test. The excellent performance identified in the four-ball testing predicts extended equipment life and reduced energy consumption. Over 50 years of commercial use more than amply demonstrate that the field performance correlates well with this laboratory data.

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 to 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.
