Application

Formulated with ethyl cellulose in cyclohexanone, terpineol, and diethylene glycol methyl ether for inkjet printing.
Curing condition: Photonic annealing, >4 J/cm2 incident (Xe flash lamp) (substrate dependent - most effective for low thermal conductivity/thermal mass substrates i.e., glass, polyimide, PEN, PET) or thermal annealing at 275-350 °C for 20-30 min.
