Description

Dodecafluoroheptylpropyl Methyl Dimethoxysilane is a high-performance fluorinated organosilane coupling agent. This compound is engineered to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to surfaces and materials. It is a critical raw material for formulators and manufacturers seeking to create durable, low-surface-energy coatings and composites. Key industries that utilize this advanced silane include specialty coatings, advanced textiles, and high-performance elastomers.

Application

• As a key additive in anti-fingerprint and easy-clean coatings for touchscreens, glass, and metals.
• As a surface modifier to create superhydrophobic and oleophobic finishes on textiles, leather, and non-woven fabrics.
• As a coupling agent in fluorosilicone rubber and sealant formulations to enhance chemical and fuel resistance.
• For the surface treatment of fillers and pigments to improve dispersion and compatibility in fluoropolymer matrices.
• In the formulation of release coatings and mold-making materials requiring excellent non-stick properties.
• As a primer or adhesion promoter on difficult-to-bond substrates like fluoropolymers (PTFE, PVDF).

Quality Control

Our Dodecafluoroheptylpropyl Methyl Dimethoxysilane 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. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all critical specifications. Our quality commitment ensures the material meets the stringent requirements for advanced material synthesis and surface modification applications.

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). Due to its moisture-sensitive (hygroscopic) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
