| Abstract: | Hyperbranched polymers were explored to develop UV-curable, protective coatings for aluminum 2024-T3 and their viscoelastic and mechanical properties were characterized using nanoindentation techniques. The coating system consists of a hyperbranched polyester acrylate (CN2300, Sartomer Inc), a modified hyperbranched polyols, and a photoinitiator (Irgacure 2022). Two different hyperbranched polyols (DPP130 and P1000, Perstorp Polyols Inc.) were partially modified with acryloyl chloride to give acrylate functionality for UV curing. The quasi-static indentation results showed that the reduced modulus and hardness of the UV-cured coatings were significantly affected by the type and amount of the modified polyols. |
