Description

n-(3-Methacryloxy-2-Hydroxypropyl)-3-Aminopropyltriethoxysilane: 50% In Ethanol is a high-performance, dual-functional organosilane coupling agent designed to create strong, durable bonds between inorganic substrates and organic polymer matrices. This product is essential for enhancing the mechanical properties, adhesion, and long-term stability of composite materials. It is primarily used by manufacturers in the coatings, adhesives, sealants, elastomers (CASE), and advanced composites industries seeking to improve product performance and reliability.

Application

• Fiber-Reinforced Composites: As a coupling agent for glass, carbon, or aramid fibers to improve resin wet-out, interfacial adhesion, and composite strength.
• Adhesives & Sealants: To enhance adhesion to difficult substrates like glass, metals, and minerals, improving bond strength and moisture resistance.
• Coatings & Paints: As an additive to promote adhesion of polymer coatings to metal, glass, and mineral surfaces, increasing durability and corrosion resistance.
• Mineral-Filled Plastics & Elastomers: To treat fillers like silica, clay, or talc, improving dispersion, reducing viscosity, and enhancing mechanical properties in the final compound.
• Dental & Biomedical Composites: For surface modification of fillers in restorative materials to achieve superior mechanical strength and biocompatibility.
• Rubber Compounding: To improve the bonding between silica fillers and rubber polymers, enhancing tear strength, abrasion resistance, and reducing rolling resistance in tires.

Quality Control

Our n-(3-Methacryloxy-2-Hydroxypropyl)-3-Aminopropyltriethoxysilane is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and solvent content is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature as a solution in ethanol, keep containers tightly sealed when not in use. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong oxidizing agents.
