Abstract :
The PTF-technology is an additive process. The polymer pastes are structuring applied on a substrate by a screen printing process. Afterwards the structured polymer paste cures by a UV or thermal radiation. Thermal processes require temperatures of 60 to 200°C and curing times of 3 to 60 minutes. UV curing takes only 2 minutes but they have a great disadvantage. UV curing pastes required photoinitiators to start the polymerisation but these initiators have a negative influence of the long-term stability.
