Capstone™ FS-35 is an APEO and VOC free, nonionic fluorosurfactant that provides exceptionally low surface tension to water-based or solvent-based formulations at very low usage rates. The reduction of surface tension provided by Casptone™ FS-35 makes it an ideal wetting and leveling aid for coating, ink, cleaner, and floor care formulations.. Capstone™ FS-35 is compatible with resins of any ionic class and it's stability in acidic, basic, and hard water environments make it exceptionally easy to incorporate into a variety of formulations. Capstone™ FS-35 has low foaming properties and will resist the formation of foam when agitated. It is available commercially as a 25% solids solution in 5 gallon pails and 55 gallon drums.

Note: All samples and purchases of Capstone for new projects and applications must first be evaluated for approval by ChemPoint and Chemours.
