Description

Silane, Triethoxy(3,3,3-Trifluoropropyl)- CAS NO 681-97-0 is a specialized organosilicon compound featuring a trifluoropropyl group, making it a key fluorinated silane coupling agent. This product is engineered to provide superior surface modification, enhancing adhesion, hydrophobicity, and chemical resistance in composite materials. It is essential for manufacturers in the advanced materials, coatings, and electronics sectors seeking to improve the performance and durability of their products.

Application

• As a coupling agent for fluoropolymer composites and fluorinated elastomers.
• Surface treatment of fillers (e.g., silica, glass) to impart hydrophobic and oleophobic properties.
• Modifying glass or mineral surfaces to enhance adhesion with fluorinated resins in coatings and sealants.
• Used in the formulation of release coatings and anti-stick surfaces.
• Imparting water and oil repellency to textiles and fibers.
• A precursor in the synthesis of more complex fluorinated siloxanes and silicone polymers.
• Potential use in the fabrication of low-surface-energy coatings for optical or electronic components.

Quality Control

Our production of Triethoxy(3,3,3-Trifluoropropyl)silane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer requirements.

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); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain product integrity.
