Description

(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl)Tripropoxysilane is a high-performance fluorinated organosilane coupling agent, engineered to impart exceptional surface properties. Its core value lies in creating durable, low-surface-energy coatings that provide outstanding water, oil, and stain repellency. This product is essential for manufacturers in the advanced materials, coatings, 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 additive in high-performance paints, varnishes, and industrial coatings for enhanced chemical resistance and easy-clean properties.
• Coupling agent in composite materials to improve adhesion between fluorinated polymers and inorganic substrates like silica or glass fibers.
• Waterproofing and stain-resistant treatment for technical textiles, non-wovens, and leather.
• Surface primer or treatment for optical components and electronic displays to provide anti-fingerprint and anti-smudge characteristics.
• Modification of nanoparticles and fillers to improve their dispersion and compatibility in fluoropolymer matrices.

Quality Control

Our (3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecyl)Tripropoxysilane 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 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). 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. Keep away from heat and incompatible materials.
