HPA

2-hydroxypropyl acrylate

HPA is a hydroxyl functional acrylic monomer used in high performance coating applications. HPA can be used to attach hydroxyl groups to an acrylic polymer backbone to create sites for reaction with a variety of cross-linking agents. Compared with hydroxyalkyl methacrylates, HPA allows faster curing cycles and reduced baking temperatures. It can also be formulated at higher solids in coating applications.
