Description

Zonyl Fs-300 is a high-performance fluorosurfactant known for its exceptional ability to dramatically lower surface tension in aqueous and solvent-based systems. This property is critical for achieving superior wetting, leveling, and spreading in demanding industrial formulations. It is an essential additive for manufacturers in the coatings, inks, adhesives, and cleaning product industries who require enhanced performance and stability. The compound is supplied under the identifier CAS No. 197664-69-0.

Application

• As a powerful wetting and leveling agent in high-quality industrial and architectural coatings.
• To improve substrate wetting and film formation in printing inks, including those for plastics and metals.
• As a key additive in fire-fighting foams (AFFF) to ensure rapid spreading and film formation.
• To enhance the surface activity and cleaning efficiency of industrial and institutional cleaners.
• In adhesive formulations to improve spreadability and contact on low-energy surfaces.
• As a flow control and anti-cratering agent in solvent-based coating systems.
• For use in electronic coatings and photoresists where precise wetting is required.
• In agricultural chemical formulations to enhance the coverage and adhesion of active ingredients.
