2-Hydroxyethyl Methacrylate, or HEMA (CAS 868-77-9), is a monomer that punches well above its weight in terms of its versatility and impact across various industries. Characterized as a colorless, transparent liquid, HEMA serves as a critical building block for advanced polymers, finding its way into everything from high-performance coatings and durable adhesives to sophisticated medical devices. As a leading supplier of fine chemical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. understands the extensive utility of this compound and is committed to providing consistent, high-quality HEMA to meet global demand.

The unique chemical architecture of HEMA, featuring a methacrylate ester and a pendant hydroxyl group, endows it with exceptional reactivity. This hydroxyl group is key to many of its applications. In the realm of coatings, HEMA's incorporation into acrylic resins allows for subsequent cross-linking, which significantly enhances the final coating's hardness, chemical resistance, and adhesion to substrates. This makes it ideal for demanding applications like automotive paints, where long-term gloss retention and durability are essential.

In the medical field, HEMA's hydrophilicity and biocompatibility are paramount. It is a foundational monomer for creating hydrogels, soft and water-absorbing materials that are widely used in the manufacture of soft contact lenses. The ability of HEMA-based hydrogels to retain water and allow oxygen permeability is crucial for wearer comfort and eye health. Furthermore, these biocompatible properties extend its use to other medical applications such as wound dressings and drug delivery systems, where controlled release and interaction with biological tissues are necessary.

For formulators and procurement specialists, knowing where to buy HEMA from a reliable manufacturer is crucial. The consistency in purity (typically ≥98%) and the proper stabilization of HEMA are vital for predictable polymerization behavior and end-product performance. NINGBO INNO PHARMCHEM CO.,LTD. offers HEMA sourced from reputable facilities in China, providing competitive price options for bulk purchases. We aim to be your trusted partner, ensuring a stable supply of this indispensable monomer for your innovative product development.
