Description

[(6,8-Dibutyl-2,4,6,8-Tetramethylcyclotetrasiloxane-2,4-Diyl)Di(Oxy)]Bis(Diethylamine) CAS NO 60228-81-1 is a specialized organosilicon compound featuring a unique cyclotetrasiloxane core functionalized with diethylamine groups. This molecular structure makes it a valuable reactive intermediate and surface modifier in advanced material synthesis. It is primarily sought by R&D and production teams in the silicone polymer, specialty coatings, and adhesives industries for developing materials with tailored surface properties and reactivity.

Application

• Silicone Polymer Modification: Acts as a functional monomer or cross-linking agent to introduce amine functionality into silicone elastomers and resins, altering their adhesion and compatibility properties.
• Surface Treatment Agent: Used to modify inorganic surfaces (e.g., silica, glass, metals) to improve adhesion of subsequent coatings or to create specific surface energies.
• Adhesive & Sealant Formulation: Serves as an adhesion promoter and curing agent component in high-performance silicone-based adhesives and sealants.
• Pharmaceutical & Cosmetic Intermediates: Potential use as a building block in the synthesis of siloxane-based compounds for controlled release or delivery systems.
• Lubricant & Release Agent Additive: Incorporated into specialty lubricants and mold release agents to enhance surface activity and thermal stability.
• Research & Development: A key intermediate in organic and organometallic chemistry research for constructing complex siloxane architectures.
