title: The Effect of 3-Isocyanato-1-Propene on Adhesive Properties of UV-Curing Urethane/Siloxane Acrylate Resin.
abstract: We synthesized the urethane/siloxane acrylate oligomer from isophorone diisocyanate (IPDI), hydroxyl alkyl terminated polydimethylsiloxane and 2-hydroxyethyl acrylate (2-HEA). UV-curable resins were formulated from the synthesized oligomer, ethylene glycol phenyl ether acrylate (PHEA), 1,6-hexanediol diacrylate (HDDA), trimethylolpropane triacrylate (TMPTA) as a reactive diluent, 3-isocyanato-1-propene as an adhesion promoter and photoinitiators. The PET film was treated with plasma in order to introduce the functional group on the PET surface and the functional group was observed through X-ray photoelectron spectroscopy (XPS) and the Fourier transform infrared (FT-IR). The adhesion strength between the PET film and the UV-cured resin were increased by using the adhesion promoter. Also, the thermal stability, the modulus and surface hardness were increased, as the adhesion promoter was added.
