Capstone® (Previously Zonyl®) Fluorosurfactants

Capstone® Fluorosurfactants are fluorocarbon-based surfactants which are extremely effective surfactants used at extremely low concentrations (0.001% to 0.1%) to enhance wetting, levelling, anti-cratering, dirt pick-up resistance and oil repellency in many applications including paints, waxes, polishes, cleaners, films and adhesives. 

In water-based and solvent-based coatings Capstone® Fluorosurfactants are used to improve a coatings appearance, for example, by reducing surface defects and improving dirt pick-up resistance.  

In films Capstone®’s provide anti-block, anti-stat, levelling for even film thickness, wetting and water repellency.  It also acts as a release aid to remove the film from the belt.  Films can be post-treated to enable them to accept coatings.

Popular Capstone® grades are detailed in the table below, other grades are available.
