Description

n-(Hydroxyethyl)-n-Methylaminopropyltrimethoxysilane: 75% In Methanol is a specialized organofunctional silane coupling agent designed to enhance adhesion and compatibility between inorganic materials and organic polymers. This product matters for its dual functionality, providing both hydrolyzable methoxysilyl groups for bonding to substrates and an amino-alcohol moiety for reactivity with resins and improved surface wetting. It is essential for formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in fiberglass and mineral-filled composite production, 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 glass fibers, minerals (e.g., silica, clay), and metals to improve resin matrix bonding in composites.
• Primer or additive to enhance the water resistance and corrosion protection of metal surfaces.
• Modifier for silica and other fillers in silicone rubber and other elastomeric compounds to reduce viscosity and improve dispersion.
• Crosslinking agent or co-monomer in the synthesis of specialty silane-modified polymers (e.g., MS Polymers).
• Improving the interfacial strength in fiber-reinforced plastics (FRP) and sheet molding compounds (SMC).

Quality Control

Our production of n-(Hydroxyethyl)-n-Methylaminopropyltrimethoxysilane adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including assay, identity confirmation, and impurity profiling, to ensure consistency and performance. Certificates of Analysis (COA) detailing purity, solvent content, and other critical parameters are 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, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, keep containers tightly sealed when not in use and away from moisture and heat sources. Use appropriate grounding and bonding procedures during handling to prevent static discharge.
