Application
2-Hydroxypropyl methacrylate (HPMA) is a versatile, clear, colorless liquid with a sweet, pungent odor, primarily utilized as a functional monomer in various industrial applications. Its primary purpose is to enhance the properties of acrylic polymers used in the production of adhesives, inks, and coatings, particularly for automotive, appliance, and metal surfaces. HPMA improves adhesion, provides cross-linking sites, and increases resistance to corrosion, fogging, and abrasion. It serves a critical role in creating solid and emulsion polymers, acrylic dispersions, and acrylic polyols, making it indispensable in textile coatings, automotive components, refurbishment coatings, and industrial applications. Additionally, HPMA is an effective comonomer in styrene-based unsaturated polyesters, PMMA-based acrylic resins, and vinyl ester formulations, used in diverse areas such as anchor bolts and chemical anchors. Its hydrophobic hydroxyl groups make it particularly valuable in manufacturing sealants for vacuum impregnation of cast aluminum components and in producing flexible UV-curable photopolymer printing plates.
