Description

Diethyl(Hydroxy)Isopropylsilane is a specialized organosilicon compound, specifically a functionalized silane, characterized by its unique combination of ethyl, isopropyl, and reactive hydroxyl groups. This structure makes it a valuable intermediate and coupling agent in advanced material synthesis, offering precise control over surface modification and polymer properties. It is essential for manufacturers and R&D teams in the silicone polymers, specialty coatings, and adhesives industries seeking to enhance material compatibility, adhesion, and performance.

Application

• Silicone Polymer Modification: Acts as a chain extender or cross-linking agent to tailor the flexibility, thermal stability, and mechanical properties of silicone elastomers and resins.
• Surface Priming & Adhesion Promotion: Used as a coupling agent to improve the bond between inorganic substrates (glass, metals, minerals) and organic polymers in coatings, sealants, and composite materials.
• Pharmaceutical & Agrochemical Intermediates: Serves as a key synthetic building block for introducing the silane moiety into more complex molecules in fine chemical synthesis.
• Hydrophobic Surface Treatments: Employed to create water-repellent coatings on surfaces for textiles, construction materials, and electronic components.
• Silylation Reagent in Organic Synthesis: Used to protect hydroxyl groups or introduce silicon-containing functional groups during multi-step synthetic processes.
• Nanomaterial Functionalization: Facilitates the surface modification of nanoparticles (e.g., silica, metal oxides) to improve dispersion and compatibility in polymer matrices.

Quality Control

Our Diethyl(Hydroxy)Isopropylsilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

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 product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong oxidizing agents.
