Description

Poly(2-Hydroxyethyl Acrylate) is a versatile, functional acrylic monomer featuring a reactive hydroxyl group. This chemical structure makes it a critical building block for synthesizing polymers with enhanced adhesion, hydrophilicity, and crosslinking capabilities. It is essential for formulators and manufacturers in the coatings, adhesives, and biomedical sectors seeking to improve product performance and functionality.

Application

• UV-Curable Coatings & Inks: Serves as a reactive diluent and crosslinker to enhance adhesion to various substrates and improve film flexibility.
• Hydrogel Synthesis: A key monomer for producing soft contact lenses, wound dressings, and other biomedical hydrogels due to its biocompatibility and water-absorbing properties.
• Pressure-Sensitive Adhesives (PSAs): Incorporated to adjust tack, peel strength, and moisture resistance in adhesive tapes and labels.
• Acrylic Resin Modification: Used to introduce hydroxyl functionality into acrylic copolymers for improved solvent resistance and crosslinking in industrial and automotive coatings.
• Fiber & Textile Treatment: Applied as a coating agent to modify fabric surfaces for moisture management, anti-static properties, or dyeability.
• Dental Materials: Utilized in the formulation of dental composites and restorative materials for its bonding characteristics.

Quality Control

Our Poly(2-Hydroxyethyl Acrylate) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, hydroxyl value, and residual monomer content. A Certificate of Analysis (COA) detailing key specifications is provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
