Description

2-Chloroethyl Methacrylate is a specialized methacrylate monomer featuring a reactive chloroethyl group. This compound matters for its dual functionality, serving as a key building block for introducing both polymerizable methacrylate and modifiable chloroalkyl groups into advanced materials. Industries requiring custom acrylic resins, specialty adhesives, and functional polymer coatings will find this monomer essential for synthesizing materials with tailored properties such as enhanced adhesion, cross-linking capability, or further chemical derivatization.

Application

• Synthesis of Functional Acrylic Polymers: Used as a co-monomer to incorporate reactive chloromethyl sites into acrylic and methacrylic copolymer chains for subsequent modification.
• UV-Curable Resins & Coatings: A valuable component in formulations for UV-curable inks, coatings, and adhesives, where it contributes to cross-linking density and final material properties.
• Production of Ion-Exchange Resins: Serves as a precursor monomer for the manufacture of anion-exchange resins after amination of the chloroethyl group.
• Biomedical & Hydrogel Materials: Employed in creating hydrogels and biomedical polymers where the chloro group allows for conjugation with biomolecules or further functionalization.
• Adhesive & Sealant Formulations: Enhances the adhesion and chemical resistance of industrial and structural adhesives.
• Surface Modifying Agents: Used to graft functional layers onto various substrates (e.g., glass, metals) to alter surface characteristics like wettability or reactivity.

Quality Control

Our 2-Chloroethyl Methacrylate is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results for identity, assay, and impurity profiles are provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) and minimize headspace in opened containers to prevent polymerization and degradation. Keep away from heat, sparks, and open flame.
