In the vast landscape of industrial chemicals, certain compounds distinguish themselves through their unique chemical properties and widespread applicability. 2-Hydroxypropyl Methacrylate (HPMA), identified by the CAS number 27813-02-1, is one such compound, playing a critical role as a functional monomer in numerous manufacturing processes. For scientists and engineers seeking to understand and leverage its potential, a detailed exploration of its properties and applications is essential.

HPMA is characterized by its molecular formula C7H12O3 and a molecular weight of approximately 144.17 g/mol. At room temperature, it presents as a clear, colorless liquid. This liquid form, combined with its relatively low viscosity and a specific boiling point of around 96°C at 1.33kPa, makes it highly manageable in various industrial settings. The density of HPMA is approximately 1.066 at 25°C, and it exhibits good solubility in water and common organic solvents, which further enhances its utility in diverse formulation processes.

The chemical structure of HPMA is key to its functionality. It is an ester of methacrylic acid, featuring a pendant hydroxyl group (-OH) on the propyl chain. This hydroxyl group is reactive and can participate in a variety of chemical reactions, most notably esterification and etherification. More importantly, in polymerization, this hydroxyl group can contribute to enhanced adhesion to substrates, act as a site for subsequent crosslinking, and influence the hydrophilic-nature of the resulting polymer. This makes HPMA a valuable building block for creating polymers with tailored surface properties and functionalities.

One of the primary applications of HPMA is as an active diluent and crosslinking agent in radiation curing systems. In UV and electron beam curing processes, HPMA helps to reduce the viscosity of formulations, leading to easier application. Crucially, it participates directly in the polymerization, contributing to the crosslinked network structure. This results in cured films with improved hardness, scratch resistance, and chemical stability. For manufacturers in the printing ink and coatings industries, sourcing high-purity HPMA from a reliable supplier like NINGBO INNO PHARMCHEM CO.,LTD. is vital for achieving optimal curing results.

HPMA is also a cornerstone in the production of acrylic resins. When copolymerized with other acrylic monomers, it yields resins with incorporated hydroxyl functionality. These hydroxyl-functionalized acrylic resins are indispensable in the creation of two-component polyurethane coatings, providing excellent durability, flexibility, and resistance to environmental factors. These are widely used in automotive finishes, industrial maintenance coatings, and architectural paints. For companies looking to buy these essential resin components, HPMA is a critical raw material to consider from a leading manufacturer in China.

Beyond coatings, HPMA serves as a modifier for plastics and rubber, enhancing their mechanical properties and processing characteristics. Its applications extend to adhesives, textile treatment agents, and even additives for decontamination lubricants. The broad utility of HPMA underscores its importance in modern chemical manufacturing. For procurement managers seeking to ensure a consistent and cost-effective supply of this versatile monomer, investigating competitive pricing from reputable China suppliers is a strategic approach.
