摘要:
Method for the production of adhesive-coated articles, articles obtainable thereby and their use A method for the production of adhesive-coated articles comprises the steps of: (I) providing a substrate; (II) applying a first polyurethane and/or polyurethane-polyurea polymer onto the substrate, the first polyurethane and/or polyurethane-polyurea polymer being capable of attaining an at least partially crystalline state with a final degree of crystallinity and wherein during and/or after the application the first polyurethane and/or polyurethane-polyurea polymer is present in a non-crystalline state. The method further comprises the steps: (III) applying onto the first polyurethane and/or polyurethane-polyurea polymer of step (II) a composition comprising a mixture of a second polyurethane and/or polyurethane-polyurea polymer and furthermore an acrylate polymer, wherein the application is performed while the degree of crystallinity of the first polyurethane-polyurea polymer is lower than its final degree of crystallinity; and (IV) cooling the article obtained to a temperature below the glass transition temperature of the acrylate polymer.
