Abstract (en)

[origin: EP0949013A2] Coupling agent layers are applied onto a strip material (1) by low pressure plasma polymerisation as the strip moves continuously through a plasma zone (3), the plasma being produced by electrical discharge, preferably a kHz, MHz or GHz discharge. An Independent claim is also included for a use of the coupling agent between the carrier strip (1) and adhesive on a single or double sided adhesive strip. Preferred features: A coupling agent coating is applied under a gas pressure of 10<-3> to 20 mbar and the electrical discharges are pulsed. The strip material moves at NOTLESS 0.1 m/min, preferably NOTLESS 50 m/min giving coating times NOTGREATER 1 minute, preferably NOTGREATER 1 second. The unwinding station (2), winding up station (9) and plasma zone (3) are housed in a vacuum chamber or the strip material can be guided through vacuum sluices into the plasma zone. The coupling agent is almost or completely transparent.
