Description

3-Chloro-2-Hydroxypropyl Methacrylate is a bifunctional monomer containing both a polymerizable methacrylate group and a reactive chlorohydrin group. This unique structure makes it a valuable intermediate for introducing cross-linking sites, adhesion-promoting functionalities, and reactive handles into polymer chains. It is primarily sought after by formulators and polymer chemists in the coatings, adhesives, and specialty materials industries to enhance product performance, durability, and chemical resistance.

Application

• Reactive Diluent & Cross-Linker in UV-curable coatings, inks, and adhesives to improve hardness and chemical resistance.
• Adhesion Promoter in primers and surface treatments for metals, plastics, and glass.
• Polymer Modification for synthesizing specialty acrylic resins with pendant reactive groups for further functionalization.
• Hydrogel Synthesis as a cross-linking agent for biomedical and contact lens materials.
• Ion-Exchange Resins precursor for creating functional polymers with anion-exchange capabilities.
• Textile & Leather Finishes to impart durable water repellency and stain resistance.
• Paper Coating Additive to enhance strength, printability, and barrier properties.

Quality Control

Our 3-Chloro-2-Hydroxypropyl Methacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including assay, purity, and identity confirmation, to ensure it meets precise specifications and is free from unintended impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen) to minimize oxidation. Keep away from heat, sparks, and open flame. Isolate from strong oxidizing agents and bases.
