Product Overview
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.

Problems Solved
Surface defects caused by poor leveling.
Poor wetting of surfaces by water-based inks.
Insufficient penetration of floor care products due to high surface tension.
When added to floor care, paint, or ink formulations at use rates ranging from 0.01-0.1% actives, Capstone™ FS-35 provides drastic improvement of wetting and leveling. This leads to a reduction of surface defects like cratering, orange peel, and pinholes.

In cleaning solutions Capstone™ FS-35 is added at rates of 0.01-0.1% actives to increase wetting of oils and improve penetration of the surface to improve overall cleaning performance.
