Description

1,1,5,5,5-Hexamethyl-3-(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)-3-[(Trimethylsilyl)Oxy]Trisiloxane is a specialized fluorinated organosilicon compound that combines the low surface energy of fluorocarbons with the flexibility and thermal stability of siloxanes. This unique hybrid structure makes it an exceptional material for creating durable, low-energy surfaces and modifying interfacial properties in demanding environments. It is primarily utilized by formulators and manufacturers in the coatings, electronics, and specialty materials sectors seeking advanced performance characteristics.

Application

• Surface Modifier for Coatings: Imparts exceptional water, oil, and stain repellency to architectural, automotive, and industrial coatings.
• Release Agent Intermediate: Used in the synthesis of high-performance mold release agents for plastics, rubber, and composite manufacturing.
• Additive for Electronics: Enhances moisture resistance and dielectric properties in conformal coatings, encapsulants, and electronic potting compounds.
• Textile & Fiber Treatment: Provides durable hydrophobic and oleophobic finishes to technical textiles, nonwovens, and filtration media.
• Lubricant & Grease Formulation: Serves as a high-value additive to improve lubricity, thermal stability, and chemical resistance in specialty lubricants.
• Adhesive & Sealant Modification: Lowers surface tension to improve wetting and leveling in high-performance adhesives and sealants.

Quality Control

Our production of 1,1,5,5,5-Hexamethyl-3-(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)-3-[(Trimethylsilyl)Oxy]Trisiloxane adheres to a strict quality management system. Each batch undergoes rigorous analytical testing, including NMR, GC, and FTIR, to ensure chemical identity, purity, and consistency meet exacting specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from strong bases and incompatible organic solvents.
