Description

Perfluorododecyl-1H,1H,2H,2H-Triethoxysilane-Perfluorotetradecyl-1H,1H,2H,2H-Triethoxysilane is a high-performance, mixed-chain perfluoroalkyl silane coupling agent designed to impart exceptional surface properties. This compound is critical for creating durable, low-surface-energy coatings with outstanding water, oil, and stain repellency. It is primarily used by formulators and manufacturers in the advanced materials, electronics, and textile industries seeking to enhance product performance and longevity.

Application

• Surface modification agent for creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Key ingredient in protective treatments for optical lenses, solar panels, and display screens to prevent fouling and improve light transmission.
• Waterproofing and stain-resistant treatment for high-performance technical textiles and non-woven fabrics.
• Primer or additive in paints, sealants, and composite materials to improve adhesion to fluorinated substrates and moisture resistance.
• Surface functionalization of nanoparticles and fillers to improve dispersion in fluoropolymer matrices.
• Anti-fingerprint and easy-clean coatings for consumer electronics and automotive interiors.
• Release coatings for molds in polymer processing.
• Modification of porous materials like stone and concrete for water repellency.

Quality Control

Our Perfluorododecyl-1H,1H,2H,2H-Triethoxysilane-Perfluorotetradecyl-1H,1H,2H,2H-Triethoxysilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by NMR or GC, purity verification, and confirmation of functional group integrity to ensure consistent performance and reliability for your formulations. A comprehensive Certificate of Analysis (COA) is provided with every shipment.

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) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain efficacy. Keep away from heat and incompatible materials.
