Abstract
An ultraviolet curable primer for a radio-wave transmission cover of a vehicle may include about 20 wt % to about 30 wt % of urethane acrylate oligomer, about 35 wt % to about 60 wt % of monomer, about 1 wt % to about 5 wt % of photopolymerization initiator, about 0.1 wt % to about 1.0 wt % of wetting additive, and about 10 wt % to about 30 wt % of solvent, wherein the urethane acrylate oligomer comprises about 7.5 wt % to about 12.5 wt % of two-function urethane acrylate oligomer based on the total weight of the ultraviolet curable primer, and about 12.5 wt % to about 17.5 wt % of six-function urethane acrylate oligomer based on the total weight of the ultraviolet curable primer, and wherein the ultraviolet curable primer is applied to a radio-wave transmission cover comprising a multilayered oxide optical film.
