Krytox® Functional Fluid Solutions for Your Application.

Krytox® functional fluids are characterized by a mono-functional hexfluoropropylenepolyether backbone coupled with a functional end-group. Combining a traditional material with one of the functional fluids offered by Chemours allows you to lower the surface energy or glass transition temperature, or provide a lubricating layer for your material. Our scientists can help guide you and offer advice on how to incorporate the functional fluid into your material. Krytox® functional fluids are fluorinated synthetic oils based on hexfluoropropylene oxide combined with a functional end-group. Today, the end-groups offered include: carboxylic acid, called Krytox® 157FS, methyl ester, methylene alcohol, primary iodide, allyl ether and a benzene group. Carboxylic acid, methyl ester and methylene alcohol are listed on TSCA*, while the others are available under the TSCA R&D exemption. Reactions of these groups can be accomplished by employing many of the traditional synthetic methodologies used with their perfluoroalkyl analogues. The perfluoropolymer portion of the fluids contains 21.6% carbon, 9.4% oxygen and 69.0% fluorine. Their functional advantages include:

• Ability to combine the inertness of Krytox® fluid with your own substrate
• Useful in a variety of applications
• Generally nontoxic and both hydrophobic and oleophobic
• Chemically and biologically inert and silicone-free
• Low vapor pressure
• Contain no volatile organic compound (VOC) materials or chlorine

Whether you require intermediates or special-purpose additives, Krytox® offers a long list of performance characteristics that can enhance your end product. Make Chemours a part of your next functional fluid project, and take advantage of our many years of experience.
