Description

n-(Hydroxyethyl)-N,n-Bis(Trimethoxysilylpropyl)Amine, 65% In Methanol is a specialized organosilane coupling agent and adhesion promoter, supplied as a 65% solution in methanol for ease of handling and application. This compound is engineered to provide superior bonding between inorganic substrates and organic polymers, significantly enhancing composite material performance. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced composite and rubber applications where durable, moisture-resistant adhesion is required.

Application

• Adhesion Promoter in paints, coatings, and inks for improved adhesion to glass, metals, and mineral surfaces.
• Coupling Agent in fiberglass-reinforced plastics and mineral-filled polymer composites to enhance mechanical properties.
• Surface Modifier for silica, glass fibers, and other fillers to improve dispersion and compatibility in polymer matrices.
• Primer Component in sealant and adhesive formulations to ensure long-term, waterproof bonding.
• Crosslinking Agent in silicone-modified organic polymers and RTV silicone systems.
• Rubber Reinforcement agent in tire and technical rubber goods to strengthen filler-to-rubber interaction.

Quality Control

Our n-(Hydroxyethyl)-N,n-Bis(Trimethoxysilylpropyl)Amine solution is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including assay, identity confirmation, and solvent content verification, to ensure consistent performance and purity. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Due to its hygroscopic and highly volatile nature, keep the container tightly sealed when not in use and away from moisture, heat, and ignition sources. Keep away from strong acids and bases.
