Capstone™ FS-61 is an anionic fluorosurfactant that dramatically reduces surface tension of aqueous formulations. It is ideally suited for improving the performance of architectural coatings.
Capstone™ FS-61 is a water-based, anionic fluorosurfactant that is APEO and VOC free. When added in very small amounts to aqueous formulations Capstone™ FS-61 drastically reduces surface tension. The reduction in surface tension provided by Capstone™ FS-61 make it an ideal wetting, leveling, and film control additive to water-based paints and coatings. The multi-functional properties of Capstone™ FS-61 allows for the simplification of latex paint formulations. Capstone™ FS-61 is available commercially as a 14% solids solution packaged in pails, drums, and totes.
Note: All samples and purchases of Capstone for new projects and applications must first be evaluated for approval by ChemPoint and Chemours.

Blocking of paints and coatings used in architectural applications.
High surface tension that leads to insufficient wetting and leveling of water-based paints and coatings.
When added to low VOC architectural coatings at low rates, typically 0.02-0.04 active ingredients, Capstone™ FS-61 dramatically improves wetting and leveling thus reducing surface defects. In addition, when Capstone™ FS-61 is cured into a latex film it improves blocking and soiling resistance. Capstone™ FS-61 allows for the reduction of other wetting, leveling, and defoamer additives in water-based formulations and will provide an overall cost savings.
When added to specialty cleaners Capstone™ FS-61 helps to improve the cleaning efficiency. It is typically used in metal cleaning, car washes, and glass cleaners to reduce surface tension. Suggested usage rates range from 0.01-0.03% actives.
Capstone™ FS-61 is used in water-based floor care formulations including finishes, waxes, and polishes to improve wetting and reduce surface defects.
Capstone™ FS-61 also improves re-wet properties in multi-coat application.
Typical use rates in floor care applications ranges from 0.005-0.02% actives.
