Silane-modified urethane acrylate oligomer and uv-curable coating composition comprising the same

Abstract

Provided herein is an ultraviolet-curable coating composition having excellent curing stability, adhesion, and weather resistance, and a silane-modified urethane acrylate oligomer applicable thereto. According to an embodiment, a silane-modified urethane acrylate oligomer prepared from a composition comprising an acrylate monomer having a hydroxyl group, a silane monomer having an isocyanate group, and a silane monomer having an alkoxy group comprises 10 wt % to 33 wt % of the acrylate monomer having a hydroxyl group, 3 wt % to 12 wt % of the silane monomer having an isocyanate group, and 7 wt % to 35 wt % of the silane monomer having an alkoxy group, based on the total weight of the composition.
