Overview
Capstone™ FS-50 is an amphoteric fluorosurfactant that is used to significantly reduce the surface tension of water-based formulations. Capstone™ FS-50 is also used to provide sustained foam. This reduction of surface tension and sustained foaming makes Capstone™ FS-50 ideal for use in industrial and institutional cleaning products. Capstone™ FS-50 is available commercially as a 27% 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.
