Description

3-(Heptafluoroisopropoxy)Propyltriethoxysilane is a highly fluorinated organosilicon coupling agent designed to impart exceptional surface properties. This compound is critical for creating durable, low-energy surfaces with enhanced chemical resistance and water/oil repellency. It is primarily needed by manufacturers in the coatings, electronics, and advanced materials sectors seeking to improve the performance and longevity of their products.

Application

• As a key surface modifier in anti-fingerprint and anti-smudge coatings for touchscreens, optical lenses, and consumer electronics.
• As a coupling agent in fluorosilicone elastomers and sealants to enhance chemical and thermal stability.
• For the surface treatment of nanoparticles and fillers to improve dispersion and compatibility in fluoropolymer matrices.
• In the formulation of high-performance release coatings and non-stick surfaces.
• As a precursor for synthesizing advanced fluorinated hybrid materials with tailored surface energies.
• For modifying glass and ceramic surfaces to achieve superhydrophobic and oleophobic properties.

Quality Control

Our 3-(Heptafluoroisopropoxy)Propyltriethoxysilane 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 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 area 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) after opening to prevent hydrolysis and maintain product integrity.
