SINOMER®HPMA is widely used in the production of polyhydroxyacrylic acid for automotive coatings and refinish coatings as well as for industrial coatings. It is non-toxic, non-yellowing and can also be used as a comonomer in styrenic unsaturated polyester, polymethylmethacrylate acrylic and vinyl ester formulations for anchor bolts and chemical bonding. HPMA can also be blended with other commercial methacrylates and acrylates to produce emulsion polymers, especially fabric coatings and fabric sizing.
SINOMER®HPMA is a hydrophobic hydroxyl-bearing monomer that is particularly useful in the production of vacuum impregnated sealants for cast aluminum compositions and is also widely used in the production of flexible, UV-curable photopolymer printing plates.

Cas No.: 27813-02-1
Molecular Formula: C7H12O3
Chemical name: 2-Hydroxypropyl methacrylate
Synonym: Hydroxypropylmetacrylate; BisoMer HPMA;ACRYESTER HP;ROCRYL 410;Propylene glycol monomethacrylate;Methacrylic acid, monoester with propane-1,2-diol
Molecular structure:

SINOMER® HPMA (2-Hydroxypropyl methacrylate) is a hydroxy-functional methacrylic monomer containing both a polymerizable double bond and a reactive secondary hydroxyl group. This dual functionality allows it to participate in free-radical polymerization as well as reactions with isocyanates, epoxides, and acids. Compared to HEMA, HPMA offers better hydrophobic balance and improved flexibility in final polymers. Available in multiple purity grades with flexible inhibitor levels to suit diverse applications.
