  • Hydroxypropyl acrylate (HPA)

Hydroxypropyl acrylate (HPA)

2-Hydroxypropyl Acrylate (HPA), with the chemical formula C₆H₁₀O₃, is an important hydroxy-containing acrylic ester monomer. It appears as a colorless transparent liquid (may turn yellow during storage) with a characteristic pungent odor. The molecule contains both acryloyl and hydroxyl groups, exhibiting dual reactivity. This product is a key raw material for producing various functional polymers and is widely used in coatings, adhesives, medical materials and other fields.
