Description

Diethyl Amino Methyl Triethoxy Silane is a versatile organosilicon coupling agent characterized by its unique amino and alkoxy functional groups. This compound is essential for enhancing the adhesion, compatibility, and mechanical properties of inorganic materials within organic polymer matrices. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite materials and surface treatment applications.

Application

• Adhesion Promoter: Used as a coupling agent in paints, coatings, and adhesives to improve bonding to glass, metal, and mineral surfaces.
• Filler Treatment: Enhances the dispersion and interfacial bonding of silica, clay, and other mineral fillers in rubber and plastic composites.
• Surface Modification: Imparts amino functionality to silica and other inorganic particles for specialized applications in chromatography and catalysis.
• Waterproofing Agent: A key component in formulations for water-repellent treatments for construction materials like concrete and stone.
• Fiber Sizing: Improves the interfacial shear strength between glass or carbon fibers and polymer resins in reinforced composites.
• Crosslinking Agent: Functions as a co-monomer or crosslinker in silicone and hybrid polymer systems.

Quality Control

Our Diethyl Amino Methyl Triethoxy Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or titration and identity confirmation by FT-IR, to ensure it meets precise chemical and physical specifications. Certificates of Analysis (COA) documenting purity, color, density, and refractive index are available for every shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) and highly volatile nature, containers must be kept tightly sealed after opening to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
