Chemours Launches Capstone™ FS-3100 Fluorosurfactant: Setting a New Benchmark for Environmentally Friendly and High-Efficiency Surface Control

Capstone™ FS-3100 is a 100% solids amber viscous liquid, boasting exceptional efficiency as its most prominent feature. Technical data shows that even at extremely low concentrations (e.g., 10ppm), the product can significantly reduce the surface tension of aqueous solutions, with a minimum value of approximately 18 mN/m. This outstanding surface tension reduction capability endows formulations with strong wetting, penetration and leveling properties.

FS-3100 delivers excellent performance in both aqueous and solvent-based systems. It effectively eliminates craters and orange peel effects in coating applications and provides superior rewetting performance, making it particularly suitable for multi-layer coating processes.

Against the backdrop of increasingly stringent environmental regulations, the technical advantages of Capstone™ FS-3100 stand out prominently. The product is based on Chemours' advanced six-carbon fluoroalkyl chain technology, designed to eliminate the environmental and health risks associated with traditional long-chain perfluorinated compounds.

FS-3100 contains no volatile organic compounds (VOCs) or alkylphenol ethoxylates (APEOs). More importantly, it does not decompose into perfluorooctanoic acid (PFOA) and its salts, fully complying with the requirements of the U.S. Environmental Protection Agency (EPA) for the PFOA Stewardship Program.

The product maintains stability in acidic, alkaline, high-salt and hard water environments, and features extremely low foaming properties. Ross-Miles foam tests show that in a 0.1% active ingredient solution at 25°C, the initial foam volume is only 62 milliliters, with rapid defoaming within 15 minutes. This stability enables it to perform excellently even in harsh formulations with strong acidity, strong oxidizing or reducing properties.

According to market application research, Capstone™ FS-3100 demonstrates irreplaceable value in multiple high-value-added fields by virtue of its unique performance:

In floor polishes, waxes and water-based coatings, FS-3100, at an ultra-low addition level of 0.01%-0.05%, significantly enhances the wetting, leveling and anti-blocking properties of coatings. In two-component polyurethane coatings, it can effectively migrate to the coating surface and act as an active component after curing, improving surface performance.

In the electronics manufacturing field, FS-3100 serves as a scale inhibitor in zinc batteries and a low-foam surfactant in photoresist strippers, effectively improving etching efficiency and electroplating results.

In concentrated cleaning solutions, it helps formulations achieve rapid spreading and deep penetration, especially for stubborn stains that are difficult to wet, with a recommended addition level of only 0.005%-0.1%.

With the continuous global improvement of environmental and performance requirements, Capstone™ FS-3100 is emerging as the preferred surfactant solution across various industries thanks to its outstanding performance characteristics and environmental compliance advantages.

"The successful launch of Capstone™ FS-3100 reflects Chemours' technological innovation strength in the field of fluorochemistry and its firm commitment to sustainable development," said the Vice President of the High Performance Materials Division, Asia Pacific at Chemours. "We will continue to be customer-centric and continuously develop more high-performance, environmentally friendly chemical solutions to empower technological innovation and green development in various industries."
