2-Hydroxyethyl Methacrylate, widely recognized by its acronym HEMA (CAS 868-77-9), is a fundamental organic compound that serves as a critical monomer in the synthesis of a broad spectrum of polymers and copolymers. Its unique molecular structure, comprising a methacrylate ester group and a primary hydroxyl group, imbues it with a remarkable versatility that underpins its extensive use across numerous industrial sectors, including coatings, adhesives, textiles, and advanced medical materials. Understanding the properties and applications of HEMA is key for professionals involved in chemical formulation and polymer science.

Chemically, HEMA is characterized by its molecular formula C6H10O3 and a molecular weight of approximately 130.14 g/mol. It presents as a colorless, transparent, and easily flowing liquid, with a relatively low volatility and good solubility in water and common organic solvents. The presence of the hydroxyl group is particularly significant, as it allows HEMA to participate actively in various chemical reactions, such as esterification and cross-linking. This reactivity is the primary driver for its utility in creating polymers with enhanced performance characteristics like improved adhesion, increased hydrophilicity, and resistance to abrasion and chemicals.

The application of HEMA spans several key industries. In the coatings sector, it is used to synthesize hydroxyl acrylic resins that form the basis for durable and high-gloss finishes, notably in automotive paints. The ability to undergo cross-linking reactions with resins like melamine-formaldehyde or epoxy resins creates robust, long-lasting coatings. For those seeking to buy HEMA for this purpose, consistency in quality and reliable supply are paramount. Our company, as a dedicated manufacturer and supplier, ensures both.

In the adhesives market, HEMA is employed in the formulation of synthetic textile adhesives and medical polymer applications, capitalizing on its excellent bonding capabilities. Its use in medical polymers, particularly for contact lenses and hydrogels, highlights its biocompatibility and ability to absorb water, providing comfort and functionality. The demand for medical-grade HEMA necessitates stringent quality control and adherence to regulatory standards.
