Description

Methoxydimethyl(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Silane is a specialized organofluorosilane coupling agent that combines a reactive methoxysilane head with a highly fluorinated alkyl tail. This unique structure is critical for imparting exceptional surface energy modification, creating durable water, oil, and stain repellency on a variety of substrates. It is essential for manufacturers in the coatings, textiles, and advanced materials sectors seeking to engineer surfaces with enhanced performance and longevity. The compound is supplied with a CAS number of 94237-08-8.

Application

• As a key surface modifier in the formulation of high-performance, hydrophobic, and oleophobic coatings for glass, ceramics, and metals.
• As a coupling agent and additive in fluorosilicone elastomers and sealants to improve chemical resistance and release properties.
• For the durable surface treatment of technical textiles and nonwovens to achieve water and oil repellency (C6 chemistry).
• In the production of anti-fingerprint and easy-clean coatings for touchscreens, optical lenses, and consumer electronics.
• As a chemical anchor to bond fluorinated functionalities to silica nanoparticles and fillers for composite materials.
• For modifying the surface of stone, concrete, and masonry to provide long-lasting water repellency and protection.

Quality Control

Our production of Methoxydimethyl(3,3,4,4,5,5,6,6,7,7,8,8,8-Tridecafluorooctyl)Silane adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity, consistent performance, and batch-to-batch reliability. Comprehensive Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen) in a cool, dry place at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent degradation from atmospheric moisture.
