Synthesis of polyamide-silicone polyacrylate and its UV curing properties

A novel polyamide-silicone polyacrylate was prepared by reacting hexamethylene-1,6-diisocynate trimer (HDT) with γ-aminopropyl triethoxysilane and modification by β-hydroxyethyl acrylate. The structure of the oligomer was characterized by FT-IR. The physical properties of UV curing films, such as hardness, traction, flexibility, max curing speed and heat resistance were examined. Researches showed that this kind of polyacrylate has some superior properties and can be used for UV curing coating.
