Description

Bis(Methyldimethoxysilylpropyl)-n-Methylamine, 95% is a high-purity, organofunctional silane coupling agent designed for advanced material synthesis. This compound is critical for creating durable chemical bridges between inorganic substrates and organic polymer matrices, significantly enhancing composite material performance. It is essential for manufacturers in the adhesives, sealants, coatings, and specialty plastics industries seeking to improve adhesion, mechanical strength, and environmental resistance in their products.

Application

• As a key coupling agent in mineral-filled composites (e.g., fiberglass, silica, talc) for improved dispersion and interfacial bonding.
• Surface modification of nanoparticles and inorganic fillers to enhance compatibility with organic polymer systems like epoxies, polyurethanes, and polyamides.
• Formulation of high-performance adhesives and sealants with superior moisture resistance and long-term durability.
• Primer and additive in protective and decorative coatings to promote adhesion to difficult substrates like metals, glass, and plastics.
• Crosslinking agent or chain extender in the synthesis of silicone-modified organic polymers and hybrid materials.
• Treatment for glass fibers and other reinforcements used in thermoset and thermoplastic composites.

Quality Control

Every batch of our Bis(Methyldimethoxysilylpropyl)-n-Methylamine is produced and tested under a strict quality management system to ensure consistent purity and performance. We employ advanced analytical techniques including GC, HPLC, and NMR to verify chemical identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with each 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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under a dry, inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
