Description

(3-Methacrylamidopropyl)Triethoxysilane, Tech-95 is a high-purity, bifunctional organosilane coupling agent that combines a reactive methacryloxy group with a hydrolyzable triethoxysilyl group. This dual functionality makes it a critical component for enhancing the adhesion and compatibility between inorganic materials and organic polymer matrices. It is essential for manufacturers in the composites, coatings, and adhesives industries seeking to improve the mechanical properties, durability, and performance of their final products.

Application

• Glass Fiber Reinforced Plastics (GFRP): Acts as a key coupling agent to improve the bond between glass fibers and unsaturated polyester or vinyl ester resins, significantly enhancing composite strength and moisture resistance.
• Mineral-Filled Composites: Used to treat fillers like silica, talc, and clay to improve their dispersion and interfacial adhesion within polyolefin, PVC, and engineering plastic matrices.
• Adhesives and Sealants: Incorporated as an adhesion promoter, particularly for silicone-modified acrylic systems, to enhance bonding to difficult substrates like metals, glass, and ceramics.
• Coatings and Inks: Functions as a crosslinking agent and primer component to improve coating adhesion, scratch resistance, and weatherability on various surfaces.
• Rubber Compounding: Used as a coupling agent for silica-filled rubber tires and industrial rubber goods to reduce rolling resistance and improve abrasion resistance.
• Surface Modification: Applied to modify the surface of nanoparticles (e.g., silica, alumina) to make them organophilic and compatible with organic monomers for subsequent polymerization.

Quality Control

Our (3-Methacrylamidopropyl)Triethoxysilane, Tech-95 is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to ensure it meets the high purity and consistency standards required for industrial applications. A comprehensive Certificate of Analysis (COA) detailing assay, purity, and key physical properties is provided with every shipment.

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 hydrolysis and polymerization upon contact with atmospheric moisture.
