Capstone™ ST-100HS
Capstone™ ST-100HS is a water based dispersion of fluorinated acrylic copolymer designed to be used as the active ingredient in low VOC penetrating sealer for porous surfaces.
Capstone™ ST-100HS is a water-based dispersion of fluoropolymer designed to provide a durable, non-film forming, protective barrier to water and oil on porous surfaces like natural stone, concrete, and unglazed tile. It should be diluted with water to 1.5-2.5% actives applied using a brush, roller, mop, or low-pressure sprayer until the surfaces is thoroughly wet. Typical coverage rate is 3-25 square meters per liter. When compared to competitive silicone based sealers Capstone™ ST-100HS has similar water repellency but far superior oil and stain resistance.
Capstone™ ST-100HS is only approved for indoor use.
All samples and purchases of Capstone for new projects and applications must first be evaluated for approval by ChemPoint and Chemours.

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.
