Abstract
A polymer plastic front plate comprises: a plastic substrate and a hard coating layer formed on an adhesion surface of the plastic substrate. The hard coating layer comprises: organic-inorganic hybrid UV oligomer, high Tg UV resin additive, a plurality of dispersed flaky nano inorganic material, and photo initiator, so as to form a gas barrier hard coating layer with high surface dyne value (>44 dyne) on the adhesion surface of the plastic substrate. It not only has good ink printability and OCA adhesiveness, but also inhibits the diffusion of fugitive gas from polymer plastic front plates during high-temperature, high-temperature and high-humidity, high-low temperature thermal shocks and other harsh automotive industry environmental tests. The gas can be avoided from entering the OCA layer, thereby solving the problems of bubbles and delamination after the environmental tests are performed.
