hydroxyetylmetakrylat

Hydroxyethyl methacrylate, often abbreviated as HEMA, is an organic compound with the chemical formula C6H10O3. It is a monomer used in the production of polymers, particularly acrylic polymers. HEMA is characterized by the presence of both a methacrylate functional group and a hydroxyl group, making it a versatile building block in polymer chemistry.

The hydroxyl group in HEMA allows for subsequent reactions and cross-linking, which can alter the properties of the resulting polymer. This makes HEMA a valuable component in various applications. It is widely employed in the formulation of contact lenses due to its ability to absorb water, providing comfort and oxygen permeability. HEMA is also found in dental materials, including adhesives and sealants, where its properties contribute to durability and biocompatibility. Furthermore, it is used in the synthesis of hydrogels for biomedical applications, such as drug delivery systems and tissue engineering scaffolds. In the coatings industry, HEMA can be incorporated into UV-curable coatings and adhesives, enhancing their performance and adhesion. Its reactivity and hydrophilic nature are key factors in its diverse industrial uses.
