Osaka Organic Chemical Industry LTD HPA

HPA is one of the reasonable hydroxyalkyl acrylates like HEA. It is second choice for crosslinking site of acrylic resin of paintings, adhesives, inks etc. HPA is also useful to control Hydrophilicity and adhesiveness to polar substrate because of it polar hydroxyalkyl moiety. HPA has low di-ester because the reactivity of secondary hydroxyl group is lower than primary hydroxyl group.
