Preparation and properties of low odor UV cured coating

Firstly, the urethane acrylate synthesized by IPDI and HEA was reacted with antioxidant 1010 in different proportions to prepare four kinds of macromolecular low odor monomers. Then a series of macromonomers and a macromolecular photo initiator, odorless reactive diluent, and odorless auxiliary were used to prepare a new odorless photocurable coating. The chemical structure of the macromonomer was characterized by Fourier transform infrared (FT-IR). The odor and properties of the coating film were tested. The results show that the macromolecular structure of the material can reduce the odor in the process of preparation and use and improve the properties of the material to a certain extent.
