Description

1,3,5,7-Tetrakis(3,3,3-Trifluoropropyl)1,3,5,7-Tetramethylcyclosiloxanes is a high-purity, fluorinated cyclic siloxane derivative, valued for its unique combination of silicone flexibility and fluorocarbon stability. This compound is engineered to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to advanced material formulations. It is a critical intermediate and functional additive for manufacturers in the specialty polymers, high-performance coatings, and electronics sectors seeking to enhance surface properties and thermal stability.

Application

• Advanced Polymer Modification: Acts as a key monomer or cross-linker for synthesizing fluorosilicone elastomers and resins with superior fuel, oil, and solvent resistance.
• Specialty Coatings & Surface Treatments: Imparts durable water-repellent (hydrophobic) and stain-resistant (oleophobic) properties to textiles, optics, and electronic components.
• Release Agents & Lubricants: Used in high-temperature molding and industrial applications where non-stick properties and thermal stability are required.
• Electronics & Semiconductor Processing: Serves as a precursor for low-surface-energy dielectric layers or protective coatings in microelectronics.
• Additive for Specialty Fluids: Enhances the performance of high-temperature heat transfer fluids and specialty lubricants.
• Research & Development: A valuable building block for academic and industrial R&D in novel fluorinated hybrid materials.
