A weather proof pressure sensitive adhesive tape composition and a process for production thereof

A process for the production of a pressure sensitive adhesive tape composition comprising the steps of:

• a. preparing a substrate layer;
• b. applying the substrate layer with a co-binding layer comprising a non-resinous 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 at least one acrylate on the application base through a coating technique while avoiding foaming and mechanical breakdown of adhesive layer;
• e. passing the coated product to a reaction chamber, facilitating reaction of the surface layer of the coated PSAC with a condensation reactable hydroxyl (OH) group present in superheated water vapour (due to partial ionization of superheated steam) and,
• f. removing solvent through drying the pressure sensitive tape composition post coating.
