Description

2,2,3,3-Tetramethyl-4,7,10-Trioxa-3-Siladodecan-12-Ol is a specialized organosilicon compound featuring a unique polyether-silane hybrid structure. This molecular architecture provides a valuable combination of silicon-based reactivity and polyether solubility, making it a versatile intermediate for advanced material synthesis. It is primarily utilized by R&D chemists and formulation scientists in the silicone, polymer, and specialty chemical industries seeking to modify surface properties or create novel functional materials.

Application

• Silicone Surfactant & Modifier: Acts as a key intermediate for synthesizing non-ionic silicone surfactants used in polyurethane foam stabilization and as wetting agents in coatings.
• Crosslinking Agent: Serves as a reactive silane crosslinker in the production of silicone resins, elastomers, and hybrid organic-inorganic polymers (ORMOSILs).
• Coupling Agent for Composites: Used to improve the interfacial adhesion between inorganic fillers (e.g., silica, glass) and organic polymer matrices in composite materials.
• Surface Treatment: Applied to modify the surface energy and hydrophilicity of glass, metals, and other substrates to enhance coating adhesion or impart anti-fog properties.
• Pharmaceutical & Cosmetic Intermediate: Utilized in the synthesis of siloxane-based excipients and delivery agents for topical formulations.
• Lubricant & Release Agent Additive: Incorporated as a functional additive to improve the lubricity and mold release characteristics of industrial fluids.

Quality Control

Our 2,2,3,3-Tetramethyl-4,7,10-Trioxa-3-Siladodecan-12-Ol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing including GC, HPLC, and NMR to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing assay, water content, and specific impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from strong acids and bases.
