Description

Butoxyethoxydimethylsilane is a specialized organosilicon compound, also known by its CAS number 18246-71-4. This chemical serves as a versatile intermediate and coupling agent, prized for its ability to modify surfaces and enhance material compatibility. It is essential for manufacturers in the coatings, adhesives, and sealants industries seeking to improve product performance and durability.

Application

• Silicone Resin Modification: Used as a reactive intermediate in the synthesis of modified silicone polymers for high-performance coatings.
• Surface Treatment Agent: Functions as a coupling agent to improve the adhesion of organic polymers to inorganic surfaces like glass, metals, and minerals.
• Adhesive & Sealant Formulations: Enhances flexibility, weather resistance, and bonding strength in silicone-based adhesives and sealants.
• Crosslinking Agent: Acts as a crosslinker in room-temperature vulcanizing (RTV) silicone rubbers and other elastomer systems.
• Hydrophobic Coatings: Imparts water-repellent properties to surfaces in construction and protective coating applications.
• Filler Treatment: Treats inorganic fillers (e.g., silica, calcium carbonate) to improve dispersion and compatibility in plastic and composite matrices.
• Lubricant & Release Agent Additive: Serves as a precursor for additives that provide lubricity and mold release characteristics.
• Electronic Encapsulants: Used in the formulation of potting and encapsulating compounds for electronic components.

Quality Control

Our Butoxyethoxydimethylsilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets precise specifications and consistent performance for industrial applications. A Certificate of Analysis (COA) documenting purity, identity, and key physical properties is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
