Description

1H,1H,2H,2H-Perfluorooctyltriethoxysilane is a high-performance fluorinated organosilane coupling agent. This compound is critical for imparting exceptional water, oil, and stain repellency to surfaces, while also enhancing adhesion between organic polymers and inorganic substrates. It is essential for manufacturers in the advanced materials, electronics, and coatings industries seeking to create durable, low-surface-energy products. Its unique perfluorinated chain provides superior chemical and thermal stability compared to hydrocarbon-based alternatives.

Application

• Surface modification agent for creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Key ingredient in fabric and textile treatments for high-performance water and stain repellency.
• Coupling agent in composite materials to improve the interfacial adhesion between fluoropolymers and mineral fillers.
• Surface primer for improving the adhesion of paints, inks, and adhesives to low-energy substrates.
• Modifier for silica and other nanoparticles to enhance dispersion in fluorinated polymer matrices.
• Component in anti-fingerprint and easy-clean coatings for touchscreens and optical devices.
• Treatment for building materials (e.g., stone, concrete) to provide water repellency and protection.
• Used in the formulation of release coatings and mold release agents.

Quality Control

Our 1H,1H,2H,2H-Perfluorooctyltriethoxysilane is manufactured under strict quality management systems. Each batch is analyzed to ensure high purity and consistency, with key parameters including assay, identity, and clarity verified. Certificates of Analysis (COA) are provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from strong acids and organic solvents.
