Abstract: The present invention relates to a functional pressure-sensitive composition having high heat resistance and bending resistance characteristics, including: 40 to 55 wt % of a urethane acrylate oligomer, 30 to 44 wt % of an acrylate monomer, 2 to 5 wt % of a photoinitiator, 0.2 to 2 wt % of a silane coupling agent, 0.1 to 1 wt % of a light stabilizer, 0.1 to 1 wt % of an ultraviolet absorber and 0.1 to 1 wt % of an antioxidant, and an electrical component with a 3D structure using the same.

Abstract: A non-slip reinforcing bar coupler includes a coupler body, a stopper, and a thread formed on outer surfaces thereof, a cap having an insertion hole, a cap body having a thread for screw-coupling with the coupler body, and an inclined surface formed on an inner surface of the insertion hole thereof, a locker having pressing pieces that have a cross section of an arc shape, a spike protruding from an inner surface of the pressing piece, and an outer inclined surface formed on a front outer surface of the pressing piece at the same inclination as the inclined surface of the cap, the rear side of the locker being inserted into the cap, and a support member located between the coupler body and the locker, deformed when the cap is tightened, and allowing the locker to be displaced to the coupler body by a certain displacement.
