Nowadays, the wider usage of polymer and polymer composite materials in a variety of industries has increasing demands for products to have minimalized size and complex structures. Various kinds of processes were developed such as lithography methods to meet the requirements of industries. To upgrade such processes, many investments and researches have proceeded, however, the demolding step, which is very important to sustain the product dimensional stability has been excluded despite its importance. In this study, we polymerized stearyl methacrylate (SMA) on the stainless steel plate by simple solution polymerization to grant the demolding ability to the plate. The epoxy resin was dosed on the coated area and cured at 80 ℃ in the oven. SMA and release agent coated samples were prepared according to the ASTM D3164 and tested by UTM. The repetitive lap shear test has proceeded and the results proved the feasibility of surface grew polymer to replace semi-permanent releasing agents. |
