Description

2-Hydroxy-3-[3-(Trimethoxysilyl)Propoxy]Propyl Acrylate is a high-purity, dual-functional organosilane monomer that combines an acrylate group with a hydrolyzable trimethoxysilyl group. This unique structure makes it a critical coupling agent for creating durable chemical bonds between organic polymers and inorganic substrates. It is essential for manufacturers in the coatings, adhesives, and advanced composites industries seeking to enhance material performance, adhesion, and weather resistance. The compound is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial applications.

Application

• Adhesion Promoter in Coatings: Used in acrylic, polyurethane, and epoxy-based paints and coatings to dramatically improve adhesion to glass, metals, and mineral surfaces.
• Surface Modification Agent: Functionalizes silica, glass fibers, and other inorganic fillers to improve compatibility and dispersion within polymer matrices like plastics and rubbers.
• Crosslinking Agent for Silicones & Acrylates: Serves as a key component in moisture-curable sealants, adhesives, and resin systems, enabling the formation of stable, crosslinked networks.
• Dental & Medical Composites: Employed as a silane coupling agent in dental restorative materials and bone cements to bond resin phases to ceramic or glass ionomer fillers.
• Fiberglass & Composite Reinforcement: Applied as a sizing or primer on glass fibers to enhance the interfacial bond strength in fiber-reinforced plastics (FRP).
• Nanomaterial Functionalization: Used to graft polymer chains onto nanoparticles (e.g., silica, titania) for advanced nanocomposites with tailored properties.

Quality Control

Every batch of 2-Hydroxy-3-[3-(Trimethoxysilyl)Propoxy]Propyl Acrylate is manufactured and tested under a stringent quality management system. Our products undergo rigorous analytical testing, including GC, HPLC, and NMR, to ensure compliance with precise purity and performance specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, impurity profile, and physical properties is provided with each shipment to guarantee material consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize shelf life and maintain product integrity. This compound is hygroscopic (moisture-sensitive); containers must be kept sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis and polymerization.
