Description

[p-(Acryloxymethyl)Phenethyl] Trimethoxysilane is a specialized organosilicon monomer featuring both a polymerizable acrylate group and hydrolyzable trimethoxysilane functionality. This dual reactivity makes it a critical component for creating high-performance, cross-linked hybrid organic-inorganic materials. It is essential for manufacturers in the advanced coatings, adhesives, and composite materials sectors seeking to enhance product durability, adhesion, and chemical resistance.

Application

• Crosslinking Agent for Acrylic Polymers: Imparts enhanced solvent resistance, hardness, and thermal stability to acrylic coatings and pressure-sensitive adhesives.
• Surface Modification of Fillers & Pigments: Used as a coupling agent to treat inorganic surfaces (e.g., silica, glass, metals) to improve dispersion and interfacial adhesion in polymer composites.
• Synthesis of Silicone-Modified Acrylic Resins (Si-AC): A key monomer for producing hybrid resins that combine the weatherability of silicones with the film-forming properties of acrylics for exterior architectural and industrial coatings.
• Adhesion Promoter: Enhances the bond strength of coatings, sealants, and adhesives to difficult substrates like glass, metals, and engineered plastics.
• Precursor for Sol-Gel Materials: Used in the synthesis of advanced ceramic and hybrid organic-inorganic materials via sol-gel processes for optical, electronic, and protective applications.
• Fiber Sizing and Treatment: Applied to glass or carbon fibers to improve their compatibility and bonding with polymer matrices in reinforced composites.

Quality Control

Our production of [p-(Acryloxymethyl)Phenethyl] Trimethoxysilane follows stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key physical parameters is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and polymerization. Keep away from heat and incompatible materials.
