Description

1H,1H,2H,2H-Perfluorodecyltrimethoxysilane is a high-performance fluorinated organosilane coupling agent, widely recognized for its ability to impart exceptional water, oil, and stain repellency to surfaces. Its value lies in creating durable, low-surface-energy coatings that enhance material performance and longevity. This compound is essential for manufacturers in the advanced materials, electronics, and textile industries seeking to develop products with superior hydrophobic and oleophobic properties.

Application

• Surface modification agent for creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Key ingredient in anti-fingerprint and easy-to-clean treatments for touchscreens and optical lenses.
• Waterproofing and stain-resistant treatment for technical textiles, fabrics, and leather.
• Surface primer and adhesion promoter in fluoropolymer composites and high-performance paints.
• Modification of nanoparticles and fillers to improve dispersion and compatibility in polymer matrices.
• Protective coating for micro-electromechanical systems (MEMS) and electronic components.
• Treatment for stone and construction materials to provide water and oil repellency.

Quality Control

Our 1H,1H,2H,2H-Perfluorodecyltrimethoxysilane is manufactured 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 guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under an inert atmosphere such as nitrogen for long-term storage to prevent hydrolysis and maintain efficacy.
