Description

(N,n-Dimethylaminopropyl)Trimethoxysilane CAS NO 2530-86-1 is a bifunctional organosilane coupling agent featuring both reactive methoxysilyl and tertiary amino groups. This dual functionality makes it a critical component for modifying surfaces and enhancing adhesion between inorganic materials and organic polymers. It is essential for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composite materials and mineral-filled plastics, seeking to improve mechanical properties and long-term durability.

Application

• As a coupling agent and adhesion promoter in epoxy, polyurethane, and acrylic-based coatings and adhesives.
• Surface treatment for mineral fillers (e.g., silica, clay, glass beads) to improve dispersion and compatibility in polymer matrices.
• Key ingredient in fiberglass sizing to enhance the bond between glass fibers and resin in composite materials.
• Used as a crosslinking agent and catalyst in silicone-based sealants and RTV (Room Temperature Vulcanizing) rubbers.
• Modifier for mineral surfaces in pigments and printing inks to improve rheology and binding.
• Intermediate in the synthesis of more complex silane derivatives and specialty chemicals.

Quality Control

Our production of (N,n-Dimethylaminopropyl)Trimethoxysilane adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including assay, purity, and identity confirmation, to ensure it meets precise customer and industry specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistency.

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/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to hydrolysis and reduced efficacy.
