Description

(Tridecafluoro-1,1,2,2-Tetrahydrooctyl)Silane is a high-purity, fluorinated organosilicon compound. This specialty chemical is engineered to impart exceptional hydrophobic and oleophobic surface properties, making it a critical component in advanced material science. It is primarily sought after by manufacturers in the electronics, optics, and high-performance coatings industries for creating durable, low-surface-energy films.

Application

• Surface Modification Agent: Used to create water- and oil-repellent (omniphobic) coatings on glass, ceramics, and metals for optical devices and touchscreens.
• Electronics Manufacturing: Applied as a dielectric layer or moisture barrier in microelectronics and semiconductor packaging to enhance reliability.
• Textile Finishing: Imparts durable stain and water resistance to technical textiles and outdoor apparel.
• Stone & Masonry Protection: Serves as a hydrophobic sealer for concrete, marble, and granite to prevent water ingress and staining.
• Release Coatings: Used in mold release applications for plastics and composites due to its excellent non-stick properties.
• Adhesion Promotion: Functions as a coupling agent to improve the bonding between fluorinated polymers and inorganic substrates.

Quality Control

Our (Tridecafluoro-1,1,2,2-Tetrahydrooctyl)Silane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are 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). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
