Claims
- 1. A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, in which a fluid film is applied to a rotating roller by means of a fluid applicator, the pressure-sensitive adhesive system is applied in one or more layers to the fluid film, and the roller is contacted with the substrate, to transfer the pressure-sensitive adhesive system from the roller to the substrate.
- 2. The method according to claim 1, wherein the roller is a steel roller, a chrome-plate steel roller, a rubber roller or a silicone rubber roller.
- 3. The method according to claim 1, wherein the roller is temperature-controlled in a range from −10° C. to 200° C.
- 4. The method of claim 3, wherein said temperature range is 2°-50° C.
- 5. The method according to claim 1, wherein the placement of the pressure-sensitive adhesive system onto the roller takes place with the aid of a single-manifold or multi-manifold die or of a slot die.
- 6. The method according to claim 1, wherein the fluid applicator unit is temperature-controlled.
- 7. The method according to claim 1, wherein the pressure-sensitive adhesive system is crosslinked prior to transfer to the substrate.
- 8. The method of claim 7, wherein said pressure sensitive system is crosslinked prior to transfer to the substrate thermally, by ultraviolet rays, by electron beams or any combination thereof.
- 9. The method according to claim 1, wherein acrylic, natural rubber, synthetic rubber or EVA adhesives are employed as the pressure-sensitive adhesive.
- 10. The method according to claim 1, wherein the fluid film comprises water, distilled water, or both, with or without additions selected from the group consisting of alcohol, wetting agents, plasticizers and liquid aging inhibitors.
- 11. The method of claim 1, wherein said roller is manufactured from elastic material.
- 12. The method of claim 1, wherein said roller is coated with ethylene-propylene terpolymer (EPDM), fluoroelastomer, silicone rubber or other elastic material.
