Abstract
A multilayer self-adhesive fouling release coating composition includes an optional removable underlying liner; an adhesive layer applied over and to the optional underlying liner when the latter is present; and a synthetic material layer applied over and to the adhesive layer. Optionally, an intermediate silicone tie coat is applied over and to the synthetic material layer. A silicone fouling release top coat is applied over and to the synthetic material layer, or, when present, over and to the intermediate silicone tie coat. Optionally, a removable polymeric film is applied over and to the fouling release top coat.
Claims8
A multilayer self-adhesive fouling release coating composition comprising:
- a removable underlying liner;
- an adhesive layer;
- a synthetic material layer applied over and to the adhesive layer;
- an intermediate silicone tie coat applied over and to the synthetic material layer;
- a silicone fouling release top coat comprising a silicone resin and at least one fouling release agent selected from the group consisting of silicone oil, liquid paraffin, surfactant wax, petrolatum, an animal fat and a fatty acid, wherein the silicone fouling release top coat is applied over and to the intermediate silicone tie coat;
- and
- a removable polymeric film consisting of polypropylene and structured with a positive relief, wherein the removable polymeric film is applied over and to a surface of the silicone fouling release top coat such that a negative of the positive relief is transferred to the surface of the silicone fouling release top coat,
- wherein the synthetic material layer comprises a polypropylene-based elastomer selected from the group consisting of non-oriented polypropylene, bi-oriented polypropylene and blown propylene, or any combination thereof, which synthetic material layer is treated on one or both surfaces using a corona treatment or a plasma treatment resulting in one or more of acrylic functional groups and carboxylic functional groups on a surface of the synthetic material layer,
- wherein the removable underlying liner is applied over and to the adhesive layer and the removable underlying liner comprises a clay coated backing paper coated by an addition-curable siliconized coating, wherein the paper in the clay coated backing paper is humidified and contains 3% by weight or more of water.
