Claim 3:
4. A process for the production of a pressure sensitive adhesive tape composition comprising the steps of:
a. preparing a substrate layer;
b. coating the substrate layer with a co-binding layer comprising a polyorganosiloxane by a coating technique and drying the substrate layer and the co-binding layer to obtain an application base;
c. treating the application base through surface treatments mechanisms comprising corona discharge treatment, plasma treatment, UV-ray irradiation, acid treatment, alkali treatment, anti-static treatment or primer coating, and combinations thereof;
d. coating a pressure sensitive adhesive composition comprising an acrylate on the application base through a coating technique;
e. passing the coated product to a reaction chamber, facilitating reaction of a surface layer of the coated pressure sensitive adhesive composition with a condensation reactable hydroxyl (OH) group, obtained by reacting the acrylate with superheated partially ionized steam in the presence of a catalyst; and
f. drying the pressure sensitive tape composition.
