Description

2-Hydroxypropyl Acrylate (2-HPA) is a functional monomer combining hydroxyl and acrylate groups, making it highly reactive in free radical polymerization systems. It offers strong adhesion, flexibility, and cross-linking capability, making it valuable in coatings, adhesives, resins, sealants, and specialty polymer formulations. The hydroxyl moiety enhances hydrophilicity and adhesion to metal and glass substrates, while the acrylate functionality supports rapid curing.
