Description

7-(2-Ethoxyethoxy)-7-Ethyl-3,6,8,11-Tetraoxa-7-Silatridecane CAS NO 61667-41-2 is a specialized organosilicon compound, specifically a silane coupling agent with a unique polyether chain. This chemical matters for its ability to act as a surface modifier and adhesion promoter, bridging organic polymers with inorganic substrates. It is primarily needed by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced material science for creating composites with enhanced performance characteristics.

Application

• Adhesion Promoter: Enhances the bond strength between organic resins (e.g., epoxies, polyurethanes) and inorganic surfaces like glass, metals, and minerals.
• Surface Modification Agent: Used to treat fillers (silica, glass beads) and pigments to improve their dispersion and compatibility within polymer matrices.
• Crosslinking Agent: Functions in moisture-curable systems, such as sealants and RTV silicones, to provide improved mechanical properties and durability.
• Coatings Formulation: Imparts improved scratch resistance, weatherability, and adhesion in industrial and protective coatings.
• Composite Materials: Key component in fiber-reinforced plastics (FRP) and nanocomposites to optimize the interface between fiber and resin.
• Release Coatings: Can be utilized in the formulation of controlled-release coatings for various industrial applications.
