Description

3-(Heptafluoroisopropoxy)Propyltrimethoxysilane is a high-performance fluorinated organosilane coupling agent. This compound is engineered to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to treated surfaces. It is primarily utilized in advanced material science and specialty coatings where durable, low-surface-energy properties are critical. Key industries include electronics, optics, and high-performance composites.

Application

• As a key coupling agent and surface modifier in fluorinated coatings for enhanced water and oil repellency.
• Surface treatment of glass, ceramics, and minerals to improve adhesion and compatibility with fluoropolymers.
• Modification of fillers and pigments for use in high-performance composite materials.
• Primer or adhesion promoter in optical fiber coatings and electronic encapsulants.
• Imparting release properties to molds and surfaces in manufacturing processes.
• Surface functionalization of nanoparticles for specialized applications in nanotechnology.
• Used in the formulation of anti-fingerprint and easy-clean coatings for touchscreens and displays.
• As an intermediate in the synthesis of more complex fluorinated siloxanes and polymers.

Quality Control

Our 3-(Heptafluoroisopropoxy)Propyltrimethoxysilane 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 specific batch results are available upon request to support your quality assurance and regulatory needs.

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/59-77°F). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and maintain product integrity.
