Diacid™ 1550 is capable of quickly stabilizing an emulsion, bringing oil and water phases together seamlessly in various formulations. A tighter emulation contributes to both the lubricating benefits of oil and the cooling benefits of water, and extends the life of the metalworking fluid.
In addition to its low foaming abilities and high mixed-film boundary lubrication in both semi-synthetic and water-soluble formulations, its low molecular weight makes it easy to formulate with.
When tested with a variety of different amines in an Al7075 stain test, Diacid™ 1550 showed consistent corrosion inhibition when compared with sebacic acid and a short chain diacid.
Diacid™ 1550 is capable of quickly and effectively absorbing onto a variety of surfaces including ferrous, aluminum and copper metal surfaces, making it an effective wetting agent. This allows it to provide lubricity and inhibit corrosion by creating a protective layer on a wide range of metallurgies.
Diacid™ 1550 is oil soluble and easy to formulate with when added into the oil phase of a semi-synthetic or soluble oil. The water-soluble components and bases can then be added to neutralize Diacid™ 1550, and effectively stabilize the emulsion. When neutralized with an appropriate base such as sodium or potassium hydroxide or an alkanolamine, a water-soluble salt is produced. The percentage of Diacid™ 1550 can be adjusted to optimize its benefits once its desired effects are seen. Foam production can be minimized by increasing the percentage of Diacid™ 1550 used and reducing the non-ionic emulsifier.
