Two heterogeneous substrates are closely united by photo-curable assembly process and then form so-called UV-curing adhesives and UV-curing pressure sensitive adhesive.The photo-curable adhesive is composed of a polyurethane acrylate(PUA)oligomers which have unique properties such as high breaking elongation,high tensile strength and larger molecule weight,and exhibit excellent adhesion to a variety of plastic,metal and glass substrates.The photo-curable adhesives possess distinct advantages such as good chemical resistance,good yellowing resistance,high temperature and high humidity resistance.In addition,photo-curable hot-melt pressure sensitive adhesives(UV-HMPSA)processed through hot-melt coating process are partially cross-linked by exposing only few seconds UV light to achieve excellent adhesion and cohesion.Therefore,UV-HMPSA can be applied on high temperature resistance label and foam tape field as well.Photo-curable pressure sensitive adhesives(UV-PSA)coated at normal room temperature have the characteristics of high adhesion and no residue left on the substrate,and moreover,UV-PSA can be designed for permanent lamination of self-assembly process and temporary protective tape.Photo-curable pressure sensitive adhesive is a kind of versatile material and used in broad fields.
