Abstract:
Preparation of steel coating material from urethane acrylate and electron beam curing were investigated. Ebecryl 8701 and Ebecryl 8702, Tripropylene glycol diacrylate (TPGDA) and Pentaerythrotol tri-tetraacrylate (PETIA), Maleic anhydride (2 grams) and 4-Hydroxy anisole (480 mg) were used as oligomers, monomers, and additives, respectively.The four best coating formulation obtained from this study consist of Ebecryl 8701 : Ebecryl 8702 : TPGDA : PETIA at50:0:50:0, 50:0:0:50, 25:25:0:50, and50:0:25:25, respectively. All above 4 coatings could withstand ASTM 2240 scratch test (with 6H pencil type) and had good chemical resistance (ASTM D1308) to household chemicals.
