Description

3-Divinyltriamine Propymethyldimethoxysilane is a specialized organosilicon compound featuring a unique hybrid structure combining reactive vinyl and amine functionalities with a hydrolyzable methoxysilane group. This molecular architecture makes it a highly effective coupling agent and adhesion promoter, crucial for creating durable bonds between organic polymers and inorganic substrates. It is essential for manufacturers in the advanced composites, specialty adhesives, and high-performance coatings industries seeking to enhance material compatibility and interfacial strength.

Application

• As a key adhesion promoter in fiber-reinforced polymer (FRP) composites, improving the bond between glass or carbon fibers and resin matrices.
• As a surface modifying agent for mineral fillers (e.g., silica, clay) to enhance dispersion and compatibility in rubber and plastic compounds.
• In the formulation of high-performance primers and sealants for automotive, aerospace, and construction applications.
• As a crosslinking co-monomer in the synthesis of specialty silicone-modified polymers and resins.
• For the surface treatment of pigments to prevent agglomeration and improve stability in coating systems.
• In the development of water-resistant and corrosion-protective coatings for metals and alloys.

Quality Control

Our production of 3-Divinyltriamine Propymethyldimethoxysilane adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment and is available upon request.

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) nature, containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
