Description

N,n-Dimethyl-3-(Trimethoxysilyl)Propylamine Hydrochloride is a versatile organosilicon compound that serves as a crucial coupling agent and surface modifier. Its bifunctional structure, featuring both an amine hydrochloride group and hydrolyzable methoxysilane groups, enables it to bridge organic and inorganic materials effectively. This product is essential for manufacturers in the adhesives, sealants, coatings, and composite materials industries seeking to enhance interfacial adhesion and material performance.

Application

• As a coupling agent in mineral-filled composites (e.g., glass fiber, silica) to improve mechanical strength and moisture resistance.
• As a surface modifier for inorganic fillers and pigments to promote dispersion and compatibility in polymer matrices.
• As a key intermediate in the synthesis of specialty silane adhesion promoters for sealants and adhesives.
• In the formulation of primers and coatings to enhance adhesion to challenging substrates like metals, glass, and concrete.
• For the surface treatment of nanoparticles to prevent agglomeration and improve handling.
• In the production of moisture-curable resins and crosslinking agents.

Quality Control

Our production of N,n-Dimethyl-3-(Trimethoxysilyl)Propylamine Hydrochloride adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling, to ensure consistency and compliance with customer specifications. A Certificate of Analysis (COA) documenting purity, physical properties, and other critical parameters 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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product performance.
