Abstract: The present invention provides a UV-curable semi-structural adhesive, and a UV-curable semi-structural adhesive tape. The UV-curable semi-structural adhesive comprises: 30-80 parts by weight of a polymer base material comprising a product prepared by polymerization of an (meth)acrylate composition; 20-70 parts by weight of an epoxy resin; and a photoacid generator, wherein the (meth)acrylate composition comprises: 40-65 parts by weight of a first (meth)acrylate monomer containing a secondary hydroxyl group; 35-60 parts by weight of a second (meth)acrylate monomer; and a free-radical polymerization photoinitiator. The (meth)acrylate composition does not gel when used in the package-sealed UV polymerization process for producing semi-structural adhesives, and have good compatiility with epoxy composition, enabling the production of semi-structural adhesives through a solvent-free process. In addition, the UV-curable semi-structural adhesive is in a paste state and forms a thick adhesive film on the substrate through one-time coating, simplifying the operation and allowing the adhesive layer formed after UV curing to have high adhesion strength.

Abstract: The present invention provides a curable composition, a curable adhesive film, and an adhesive tape. Specifically, the curable composition comprises, based on the total weight thereof as 100 wt %: 15-50 wt % of an ethylene-vinyl acetate copolymer; 10-40 wt % of polyvinyl butyral; and 20-60 wt % of an epoxy resin. The curable adhesive film according to the technical solution of the present invention has no tackiness at room temperature, which enables the curable adhesive film to have the ability to reposition even after being laminated on a substrate, making the curable adhesive film applicable to substrates with irregular shapes. Once initiated by UV radiation, the curable adhesive film is flowable and tacky at elevated temperatures. The cured adhesive has good bonding strength at high temperatures. The curable adhesive film features high bond strength and low odor, and can be used for void filling, especially for side panel bonding of electric vehicle battery modules in the electric vehicle (EV) market.

Abstract: The present invention provides a UV curable composition, a UV curable adhesive film and a UV curable adhesive tape. The UV curable composition comprises, based on the total weight thereof as 100 wt %: 25 to 60 wt % of an ethylene-vinyl acetate copolymer; 20 to 60 wt % of an epoxy resin; 5 to 20 wt % of glass bubbles; 0.3 to 8 wt % of a hydroxy-containing compound; and 0.5 to 5 wt % of a photoinitiator. According to the technical solution of the present invention, cohesive failure can be achieved in the cured adhesive film by the addition of glass bubbles into the UV curable system. The UV curable product provided in the present invention can achieve a good balance among the initial adhesivity, structural strength after curing, odorlessness or low odor, and other performance.
