Description

n-Octyldiisopropyl Dimethyl Amino Silane is a specialized organosilicon compound featuring a reactive amino group and a long-chain alkyl substituent. This unique structure makes it a highly effective coupling agent and surface modifier, crucial for enhancing the compatibility and adhesion between inorganic materials and organic polymers. It is primarily sought after by manufacturers in the advanced materials, coatings, and sealants industries who require improved mechanical properties, durability, and moisture resistance in their final products.

Application

• As a coupling agent in mineral-filled composites (e.g., silica, clay) to improve dispersion and interfacial bonding.
• As a surface treatment agent for glass fibers, nanoparticles, and pigments to promote organic matrix compatibility.
• In the formulation of moisture-curable sealants and adhesives as a crosslinking catalyst and adhesion promoter.
• As a key intermediate in the synthesis of more complex silane-modified polymers (SMP) and resins.
• For hydrophobic surface modification of various substrates to impart water repellency.
• In the production of release coatings and mold-making materials.

Quality Control

Our production of n-Octyldiisopropyl Dimethyl Amino Silane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed against comprehensive specifications using advanced techniques like GC, NMR, and titration. A Certificate of Analysis (COA) detailing identity, purity, and key physical properties is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after each use to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
