Description

N-(2-Hydroxyethyl)acrylamide (HEAA) is a versatile bifunctional monomer featuring both a polymerizable acrylamide group and a reactive hydroxyl group. This unique structure makes it a critical building block for synthesizing advanced polymers with tailored properties, particularly for enhancing hydrophilicity, adhesion, and crosslinking density. It is essential for formulators and polymer chemists in industries such as personal care, coatings, adhesives, and biomedical hydrogels seeking to modify material performance.

Application

• Hydrogel Manufacturing: A key monomer for producing superabsorbent polymers (SAP) and contact lens materials, imparting high water retention and biocompatibility.
• Coatings & Adhesives: Used to improve the adhesion, flexibility, and moisture resistance of acrylic-based coatings, pressure-sensitive adhesives (PSAs), and inks.
• Personal Care Products: Incorporated into hair fixative resins, skincare gels, and nail coatings to provide film-forming and conditioning properties.
• Textile & Paper Chemicals: Serves as a crosslinker in durable press finishes for textiles and as a strengthening agent in paper coatings.
• Photoresists & Electronics: Utilized in the formulation of photopolymerizable resins for lithography and electronic encapsulants.
• Drug Delivery Systems: Employed in the synthesis of stimuli-responsive polymer carriers for controlled release applications.

Quality Control

Our N-(2-Hydroxyethyl)acrylamide is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure high purity and consistency, meeting the stringent requirements for polymer synthesis. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize moisture absorption. Keep away from heat, sparks, and open flame.
