Description

Methyl[2-(3-Trimethoxysilylpropylamino)ethylamino]-3-propionate is a bifunctional organosilane coupling agent containing both amino and ester functional groups. This compound is engineered to create strong covalent bonds between inorganic materials and organic polymers, significantly enhancing composite performance. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material scientists developing reinforced plastics and surface-modified fillers.

Application

• As a coupling agent and adhesion promoter in epoxy, polyurethane, and acrylic-based coatings and adhesives.
• For the surface modification of mineral fillers (e.g., silica, glass fibers, clay) to improve dispersion and interfacial bonding in polymer composites.
• In the formulation of moisture-curable sealants and RTV silicones to enhance adhesion to various substrates.
• As a key intermediate in the synthesis of specialized silane-modified polymers (SMP) and hybrid organic-inorganic materials.
• For corrosion-resistant primer formulations on metals such as aluminum and steel.
• In the production of reinforced engineering plastics and thermoplastic composites to improve mechanical properties.

Quality Control

Our production of Methyl[2-(3-Trimethoxysilylpropylamino)ethylamino]-3-propionate adheres to a stringent quality management system. Every batch is analyzed to ensure consistency and high purity, meeting the specifications required for industrial and advanced material applications. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and clarity 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, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed after opening to prevent degradation by atmospheric moisture. Keep away from strong acids and bases.
