Description

m-(Trifluoromethyl)Phenyltrimethoxysilane is a high-purity organosilicon compound, specifically a phenylsilane derivative, that serves as a critical coupling agent and surface modifier. Its value lies in its ability to impart hydrophobic, oleophobic, and release properties to inorganic substrates, enhancing compatibility and adhesion in composite materials. This product is essential for manufacturers in the advanced materials, specialty coatings, and electronics industries seeking to improve product performance and durability.

Application

• Surface Treatment Agent: Used to modify the surface of glass, silica, and metals to improve water repellency and adhesion for coatings.
• Coupling Agent in Composites: Enhances the interfacial bonding between organic polymers and inorganic fillers in reinforced plastics and rubber.
• Silicone Resin Intermediate: Acts as a key monomer in the synthesis of specialty phenyl-containing silicone resins with high thermal stability.
• Electronic Encapsulants: Employed in the formulation of protective materials for semiconductors and electronic components due to its moisture resistance.
• Release Coatings: Functions as a component in formulations for non-stick molds and release papers.
• Adhesion Promoter: Improves the bonding of primers, inks, and paints to difficult-to-adhere substrates.

Quality Control

Our m-(Trifluoromethyl)Phenyltrimethoxysilane 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. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee it meets your specific application requirements.

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.
