Capstone™ FS-22 is a nonionic, solvent based fluoropolymer designed to provide wetting and leveling to coating formulations.
Capstone™ FS-22 is a powerful wetting and leveling aid for solvent-based formulations.
In coating formulations Capstone™ FS-22 is used in very small rates, typically 0.05-0.25% actives, to provide exceptional wetting and leveling. This helps to eliminate craters, pinholes, orange peel, and other surface defects. In addtion, when it is cured into a coating it provides the film with outstanding oil and water repellency. Capstone™ FS-22 is also be used in cleaning products to enhance wetting of difficult soils and boost the stain resistance of the treated surface.

Capstone® fluorosurfactants & fluororepellents were some of the first short-chain alternatives commercialized so Chemours has lots of experience helping their customers reformulate.
Capstone® fluorosurfactants and repellents were introduced as sustainable replacements that meet the goals of the U.S. EPA 2010/15 PFOA Stewardship Program. They are based on short-chain molecules that cannot break down to PFOA or PFOS in the environment.
