Description

1H,1H,2H,2H-Perfluorododecyltriethoxysilane is a high-performance fluorinated organosilane coupling agent, prized for its ability to impart exceptional water, oil, and stain repellency to surfaces. This compound is critical for creating durable, low-surface-energy coatings that enhance material performance and longevity. It is primarily utilized by manufacturers in the advanced materials, electronics, and textile industries seeking to develop superhydrophobic and oleophobic products.

Application

• Surface modification agent for creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Key ingredient in formulations for waterproofing and stain-resistant treatments for textiles, leather, and paper.
• Surface primer and adhesion promoter in electronic encapsulants and protective coatings for sensitive components.
• Modifier for silica nanoparticles and other fillers to enhance dispersion and compatibility in polymer composites.
• Treatment for building materials like stone and concrete to provide weather resistance and anti-graffiti properties.
• Additive in paints and coatings to improve dirt release and cleanability.
• Surface functionalization agent for microfluidic devices and lab-on-a-chip applications to control fluid flow.

Quality Control

Our 1H,1H,2H,2H-Perfluorododecyltriethoxysilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and GC, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation.
