Description

1,3-Bis(Heptadecafluoro-1,1,2,2-Tetrahydrodecyl)Tetramethyldisiloxane is a high-performance fluorinated siloxane compound, distinguished by its unique perfluoroalkyl side chains attached to a disiloxane backbone. This structure provides exceptional chemical inertness, thermal stability, and pronounced hydrophobic/oleophobic properties, making it a critical material for advanced surface modification and specialty fluid applications. It is primarily utilized by formulators and manufacturers in the electronics, coatings, and specialty chemical industries seeking to impart low surface energy characteristics to their products.

Application

• Surface Treatment Agent: Used as a key ingredient in anti-fingerprint, anti-stain, and easy-to-clean coatings for touchscreens, optical lenses, and architectural glass.
• Release Coatings: Functions as an effective release agent in mold-making processes for plastics, rubbers, and composites, providing excellent non-stick properties.
• Water and Oil Repellents: Imparts durable water and oil repellency (DWR) to textiles, leather, and paper products.
• Electronics Industry: Employed as a dielectric fluid or additive in heat transfer fluids and lubricants for sensitive electronic components due to its stability and non-flammability.
• Specialty Additive: Serves as a flow aid, leveling agent, or wetting modifier in high-performance paints, inks, and coatings.
• Intermediate for Synthesis: Acts as a valuable building block for synthesizing more complex fluorinated siloxane polymers and surfactants.
