Currently, the automotive industry is faced to environmental regulations and reducing solvent or wastes. For these reasons, the automotive pre-coated metal sheet has been investigated to remove the wet coating process, such as pre-treatment, dip coating and spray coating. In this study, we designed high flexible unsaturated polyester resin and grafted two kinds of acrylate (methyl methacrylate, 2-hydroxyethyl methacrylate) on C=C double bond of unsaturated polyester for good surface hardness and crosslinking. |
