2-Hydroxyproply Methacrylate (2-HPMA)


2-Hydroxypropyl Methacrylate (2-HPMA) is an ester of Methacrylic Acid and is used as a raw material in polymer synthesis. 2-Hydroxypropyl Methacrylate (2-HPMA) is a functional hydrophobic-hydroxy monomer, consisting of a cyclic hydrophobic group with characteristic high reactivity of methacrylate. It can form both homopolymers and copolymers. Copolymers of 2-Hydroxypropyl Methacrylate (2-HPMA) can be prepared with (meth)acrylic acid and its salts, amides, and esters, as well as with (meth)acrylates, acrylonitrile, maleic acid esters, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and other monomers.

  • Flexibility
  • Adhesion
  • Shock resistance
  • Weather resistance


2-Hydroxypropyl Methacrylate (2-HPMA) is used in the preparation of solid and emulsion polymers, acrylic dispersions in conjunction with other (meth)acrylates, and finds applications in various industries, particularly in textile coatings and garments. Additionally, it is used:

  • As a comonomer in the production of acrylic rollers for automotive components, maintenance coatings, and industrial coatings,
  • As a comonomer in styrene-based unsaturated polyesters, PMMA-based acrylic resins, and vinyl ester formulations for chemical anchors and chemical fasteners,
  • As a hydrophobic hydroxy monomer in vacuum impregnation adhesives for cast aluminum components.


  • Automotive coatings
  • Architectural coatings
  • Industrial coatings
  • Plastics
  • Hygiene products
  • Adhesives and sealants
  • Textile finishes
  • Modifications
  • Photosensitive materials
  • Additives for oil production and transportation.
