Description

Bis[3-(1H,1H,2H,2H-Perfluorooctylthio)Propyl]Fumarate is a specialized fluorinated organic compound designed to impart exceptional surface properties. This product matters for its ability to deliver high-performance, durable hydrophobicity and oleophobicity to a wide range of materials. It is primarily needed by formulators and manufacturers in the coatings, textiles, and specialty polymer industries seeking to create advanced water- and oil-repellent surfaces.

Application

• As a key monomer or additive in the synthesis of fluorinated polymers and coatings for extreme surface protection.
• To impart permanent water and oil repellency (stain resistance) to textiles, carpets, and non-woven fabrics.
• As a surface-modifying agent in high-performance paints and industrial coatings for corrosion resistance and easy-clean properties.
• In the formulation of specialty surfactants and leveling agents for fluorinated systems.
• For creating low-surface-energy release coatings used in mold manufacturing and composite materials.
• As a functional additive in inks and toners to improve flow characteristics and substrate adhesion.
• In research and development of advanced materials requiring specific fluorochemical functionality.
