For any industrial chemist or procurement specialist, a thorough understanding of a chemical's properties is the foundation for successful application and safe handling. 2-Hydroxyethyl Acrylate (HEA), a vital monomer in numerous chemical processes, possesses a unique set of physical and chemical characteristics that dictate its performance and storage requirements. As a leading manufacturer and supplier of specialty chemicals, we aim to provide clear insights into HEA's profile, ensuring our customers can effectively integrate it into their operations.

Physically, 2-Hydroxyethyl Acrylate typically presents as a clear, colorless liquid with a mild, ester-like odor. Its relatively low freezing point (< – 60 °C) ensures it remains liquid under most standard operating conditions, simplifying handling and transfer. The density of HEA is approximately 1.106 g/cm³ at 25 °C, making it slightly denser than water. Its viscosity is also a manageable characteristic for pumping and mixing operations, crucial for process engineers.

Chemically, HEA's defining feature is its dual functionality. The acrylate group provides a reactive site for polymerization, readily undergoing addition reactions. The hydroxyl group, on the other hand, offers a site for esterification, etherification, or reaction with isocyanates, allowing for diverse derivatization and crosslinking. This reactivity profile makes HEA incredibly versatile for synthesizing polymers with specific functionalities, from improved adhesion to enhanced chemical resistance.

A critical aspect of HEA's handling is its propensity to polymerize, especially when exposed to heat, light, or contaminants. To prevent premature polymerization, HEA is stabilized with inhibitors like MEHQ (Methoxyhydroquinone). Crucially, the presence of dissolved oxygen is required for the stabilizer to function effectively. Therefore, HEA must always be stored under air, never under inert gases like nitrogen. Maintaining storage temperatures below 35°C is also recommended to ensure stability and product quality. For bulk purchasers, understanding these storage requirements is key to maintaining the integrity of the material.

The shelf life of HEA is typically up to one year under recommended storage conditions. However, for extended storage periods, it's advisable to replenish dissolved oxygen. Over time, trace amounts of ethylene glycol diacrylate can increase, which might be relevant for specific sensitive applications. Following a strict 'first-in-first-out' inventory management system is crucial to minimize the likelihood of over-storage and ensure the use of the freshest material. This attention to detail is what sets apart a reliable supplier.

When considering the purchase of 2-Hydroxyethyl Acrylate, it is essential to source from a reputable manufacturer that adheres to strict quality control measures. Our company, as a dedicated supplier in China, ensures that our HEA meets high purity standards and is packaged appropriately for safe transportation and storage.
