Description

2-[(Hydroxyphosphinyl)Oxy]Ethyl Methacrylate is a specialized organophosphorus monomer that combines a methacrylate group with a phosphonic acid ester functionality. This unique structure is critical for imparting adhesion promotion, flame retardancy, and corrosion inhibition properties to polymer systems. It is an essential raw material for formulators and polymer chemists in the coatings, adhesives, and advanced materials industries seeking to enhance product performance.

Application

• Dental and Orthopedic Adhesive Composites: As a key adhesion-promoting monomer in self-etching dental primers and bone cements, bonding to tooth enamel, dentin, and metal implants.
• Corrosion-Resistant Coatings: Used in primers and metal coatings to improve adhesion to metallic substrates (e.g., steel, aluminum) and provide long-term corrosion protection.
• Flame-Retardant Polymers: Incorporated as a reactive comonomer in acrylic resins, polyurethanes, and epoxy systems to enhance flame retardancy and reduce smoke emission.
• Fiberglass Sizing and Coupling Agents: Acts as a surface treatment for glass fibers to improve the interfacial adhesion and mechanical properties of fiber-reinforced composites.
• Hydrogel and Contact Lens Materials: Utilized to create hydrophilic, biocompatible polymers with improved oxygen permeability and comfort.
• Water Treatment Scale Inhibitors: Serves as a precursor for polymers that prevent scale formation (e.g., calcium carbonate, sulfate) in industrial water systems.

Quality Control

Our production of 2-[(Hydroxyphosphinyl)Oxy]Ethyl Methacrylate adheres to strict quality management protocols. Each batch is analyzed to ensure high purity and consistency, meeting the exacting requirements for sensitive applications like dental adhesives and biomedical devices. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles 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 temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature and reactive methacrylate group, prolonged exposure to light or elevated temperatures should be avoided to maintain product stability.
