Description

[Perfluoro(Polypropyleneoxy)]Methoxypropyltrimethoxysilane, 20% In Fluorinated Hydrocarbon is a high-performance fluorinated organosilicon compound, specifically formulated as a 20% solution in a fluorinated hydrocarbon solvent. This product is engineered to deliver exceptional surface modification and coupling properties, particularly for substrates where standard silanes are ineffective. It is a critical material for industries requiring advanced chemical resistance, low surface energy, and durable adhesion in demanding environments. The CAS number for this compound is 870998-78-0.

Application

• Surface Treatment for Fluoropolymers: Acts as a primer or adhesion promoter for bonding PTFE, FEP, PFA, and other fluorinated plastics to metals, ceramics, and other polymers.
• Water and Oil Repellent Coatings: Imparts superior hydrophobic and oleophobic properties to textiles, glass, and electronic components.
• Release Coatings: Used in mold release applications for high-temperature polymers and elastomers, providing non-stick surfaces.
• Electronic Encapsulants and Sealants: Enhances the moisture resistance and environmental stability of sensitive electronic assemblies and optical devices.
• Composite Material Interface: Improves the interfacial bonding between inorganic fillers (like glass or minerals) and fluorinated polymer matrices.
• Anti-fouling and Anti-icing Coatings: Applied in marine and aerospace applications to create low-energy surfaces that resist biological fouling and ice adhesion.
