SYN-ESTER SE-315 is a polymeric sulfurized ester, extreme pressure additive. This product is inactive to copper at 212°F (100°C). It is also light in color and low odor, and as such, is an excellent replacement for sulfurized fats, esters and olefins, whether they are active or inactive sulfur containing products. SYN-ESTER SE-315 was designed to totally replace chlorinated extreme pressure additives in industrial cutting oils and water reducible soluble oils and semi-synthetics. This product is particularly useful for machining stainless steels and other hard steels, such as Hastalloy and tool steels. It also provides excellent friction modification properties which makes it suitable for many industrial lubricant applications. It is ideally suited for use in straight oils where high load bearing performance is required.
SYN-ESTER SE-315 shows exceptional solubility in a wide range of base oils, including highly refined paraffinics.
