UV Surface Treatment of Polycarbonate for Adhesion Improvement to Liquid Silicone Rubber (LSR)
(2018)
The adhesion of self-adhesive liquid silicone rubbers to thermoplasts is only possible for a few selected material combinations without a surface pretreatment. A UV pretreatment is effective for polycarbonate and short irradiation periods are sufficient. To clarify the required irradiation conditions that result in an improvement of adhesion, the varying irradiation conditions were assessed. FTIR-ATR spectroscopy was used for surface analysis to characterize the change in the polymer surface.

Greece: Austerity's unexpected allies
(2018-04)
Contrary to pre-electoral proclamations and the recent optimism of the government and its European allies, the situation since 2015 has only gotten worse.
