Description

2-Hydroxy-3-Chloropropyl Acrylate is a bifunctional monomer containing both a reactive acrylate group and a chlorohydrin moiety, making it a versatile building block for polymer synthesis. This compound is valued for its ability to introduce cross-linking sites and pendant hydroxyl groups into polymer chains, significantly enhancing adhesion, hydrophilicity, and chemical resistance in the final materials. It is primarily needed by manufacturers in the coatings, adhesives, and specialty polymer industries for developing advanced performance resins.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and cross-linker to improve film hardness, adhesion to various substrates, and cure speed.
• Adhesives & Sealants: To enhance bonding strength, flexibility, and chemical resistance in acrylic-based structural and pressure-sensitive adhesives.
• Hydrogel Synthesis: Serves as a co-monomer for creating hydrophilic and swellable polymer networks used in biomedical and personal care applications.
• Surface Modifiers: For grafting onto polymer or inorganic surfaces to impart permanent hydrophilicity and improved biocompatibility.
• Reactive Intermediate: Used in the synthesis of more complex monomers, pharmaceutical intermediates, or functionalized polymers.
• Fiber & Textile Treatment: Imparts durable softness, moisture-wicking properties, and anti-static characteristics to synthetic fibers.

Quality Control

Our 2-Hydroxy-3-Chloropropyl Acrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, color, and impurity profiles are available upon request to 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 15-25°C (59-77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent degradation from atmospheric moisture.
