Abstract: The present invention provides a UV curable adhesive, wherein based on a total weight of the UV curable adhesive, the UV curable adhesive comprises: from 30 to 70 wt % of an acrylate oligomer; from 20 to 65 wt % of an acrylate monomer; from 1 to 10 wt % of acryloyl morpholine; from 1 to 15 wt % of a photo initiator; and from 0 to 10 wt % of a thickening agent, wherein the acrylate oligomer has a weight average molecular weight in a range of from 10,000 to 100,000 grams/mole and a glass transition temperature in a range of from −50 to 0° C. According to the technical solution of the present invention, the adhesive layer obtained from curing the UV curable adhesive is relatively thick (for example, 0.8 mm), and the adhesive layer has good adhesion property, cohesive force, and tackiness.

Abstract: A curable mixture, a partially cured composition, a cured composition, an article containing either the partially cured composition or the cured composition, and a method of bonding two substrates are provided. The partially cured composition functions as a pressure-sensitive adhesive while the cured composition functions as a structural or semi-structural adhesive. The curable mixture can be applied to a first substrate by printing or dispensing, if desired.

Abstract: The present invention relates to a pressure-sensitive adhesive composition comprising an acrylate copolymer having a side carboxyl that is formed by a first monomer mixture containing a carboxyl-containing monomer, wherein, the content of the carboxyl-containing monomer is 0.1-10 wt. % based on the total weight of the first monomer mixture for forming the acrylate copolymer having the side carboxyl, the glass transition temperature Tg of the acrylate copolymer having the side carboxyl is larger than or equal to −55° C. and less than or equal to −30° C. The pressure-sensitive adhesive composition further comprises 1-25 wt. % of an acrylate oligomer with a weight-average molecular weight greater than or equal to 20,000 Da and a glass transition temperature Tg greater than or equal to 25° C., and 1-20 wt. % of a terpene tackifying resin based on the total weight of the acrylate copolymer having the side carboxyl and the acrylate oligomer. The pressure-sensitive adhesive composition also has a high peel force at room temperature and a high cohesive force at high temperature and has excellent anti-warping and anti-bubbling properties
