Abstract
A non-substrate adhesive tape with different adhesive properties on both sides and a manufacturing method of the non-substrate adhesive tape are disclosed. The adhesive tape includes heterogeneous first and second adhesive layers that have different properties from each other and are laminated by using a non-substrate primer coating layer. The adhesive tape includes a primer coating layer interposed between a first adhesive layer and a second adhesive layer, and the first adhesive layer is a silicone adhesive layer.
Claims16
A non-substrate adhesive tape with different adhesive properties on both sides, the non-substrate adhesive tape comprising:
- a first adhesive layer;
- a second adhesive layer;
- and
- a primer coating layer interposed between the first adhesive layer and the second adhesive layer,
- wherein the first adhesive layer is a silicone adhesive layer,
- an adhesive strength of the silicone adhesive layer relative to an adherend is 700 gf/in to 2,000 gf/in, wherein the adherend is not the second adhesive layer, and
- a thickness of the primer coating layer is 0.1 μm to 50 μm.
A non-substrate adhesive tape with different adhesive properties on both sides, the non-substrate adhesive tape comprising:
- a first adhesive layer;
- a second adhesive layer;
- and
- a primer coating layer interposed between the first adhesive layer and the second adhesive layer,
- wherein the first adhesive layer is a silicone adhesive layer,
- an adhesive strength of the silicone adhesive layer relative to an adherend is 700 gf/in to 2,000 gf/in,
- a thickness of the primer coating layer is 25 μm to 50 μm,
- the primer coating layer is formed by performing physical surface treatment or chemical bonding on the silicone adhesive layer, and
- the chemical bonding is performed by coating a material selected from the group consisting of an acrylic resin having a carboxyl group and a hydroxyl group, a urethane-based resin, an epoxy-based resin, a silicone-based resin, a rubber-based resin, a silicone modified resin, and any combination thereof on the silicone adhesive layer.
