Description

n-(3-Triethoxysilylpropyl)Perfluorooctanoamide is a specialized organosilicon compound that combines a reactive triethoxysilyl group with a perfluorinated carbon chain. This unique hybrid structure makes it a highly effective surface modifier, imparting both excellent adhesion to inorganic substrates and durable hydrophobic/oleophobic properties. It is primarily used by formulators and manufacturers in advanced material science to create high-performance coatings and composites. The compound is identified by CAS number 37043-12-2.

Application

• Surface Treatment Agent: Used to modify glass, metal, and ceramic surfaces to provide water, oil, and stain repellency.
• Adhesion Promoter: Enhances the bonding between fluorinated polymers or coatings and various substrates in high-performance composites.
• Textile Finishing: Imparts durable water and oil repellency (DWR) to technical fabrics and protective clothing.
• Paper and Packaging Coatings: Applied to create grease-resistant and moisture-barrier properties in specialty papers and food packaging.
• Stone and Masonry Protection: Used in formulations to protect building materials from water ingress, staining, and environmental weathering.
• Electronic Encapsulants: Serves as a coupling agent in potting compounds and encapsulants to improve moisture resistance and interfacial adhesion.

Quality Control

Our n-(3-Triethoxysilylpropyl)Perfluorooctanoamide is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by NMR or HPLC, 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 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis and maintain efficacy.
