摘要

A series of formulations were prepared with different percentages of oligomer, epoxy diac-rylate (EA-1020 ), monomer, 1,6 Hexane dio1 diacrylate,(HDDA) and different percentages of filler (Magnesium tri-silicate, Mg_2Si_3O_8). Irgacure 369 [2-Benzyl-2-dimethyl-amine-1 (4-mor-pholinophenyl) butanone-1] was used in the formulations as photoinitiator. Ultraviolet (UV) cured thin polymer films were prepared from these formulating solutions on clean glass plates. Pendulum hardness (PH), gel content and macro scratch hardness (MSH) of the UV cured films were studied. One percent Mg_2Si3O_8 containing formulation showed the premium properties. The substrates (plain board) were coated by these formulating solutions and cured under the same UV lamp at different intensities of radiation. Various properties of the coated surface such as PH, gloss, adhesion, abrasion and MSH were investigated. The base coat containing 1% Mg_2Si_3O8 and top coat containing 48% HDDA produced the best performance among all the formulations inspected. The degradable properties in different weathering conditions on PH, gloss, adhesion, abrasion and MSH were measured. The surface cured with the optimized formulation (E) again yielded the minimum loss of the properties.
