2-Hydroxypropyl Methacrylate (HPMA) – Industrial Bulk Supply for Coatings & Polymers

2-Hydroxypropyl Methacrylate (HPMA) is a versatile, high-purity monomer widely used in the formulation of resins, coatings, adhesives, sealants, and hydrogels. As a methacrylate ester containing a hydroxyl group, HPMA allows for strong crosslinking, chemical resistance, and adhesion properties in cured systems.

At RealChemStore.org, we provide industrial-grade HPMA in bulk packaging, ideal for manufacturers operating in paint, ink, polymer, electronics, and medical materials markets.

✅ Applications of HPMA

🖌️ Paints & Coatings

HPMA improves adhesion to metal, wood, glass, and plastic surfaces, and enhances resistance to weathering, abrasion, and chemicals. It’s used in both waterborne and solvent-based UV-curable and epoxy-acrylate coating systems.

🧷 Adhesives & Sealants

Due to its hydroxyl functionality, HPMA offers excellent wetting and bonding strength, especially in reactive hot melts, pressure-sensitive adhesives, and epoxy-modified systems.

🧪 Polymer Synthesis

As a reactive diluent, HPMA plays a key role in the production of thermoset acrylic resins, copolymers, and hydrophilic gels. Its compatibility with other acrylates and methacrylates enables high-performance polymer customization.

🩺 Medical & Specialty Applications

Used in hydrogels, contact lenses, drug delivery systems, and biocompatible materials, HPMA supports moisture absorption and chemical reactivity without compromising clarity or flexibility.
