Abstract
In an embodiment, a topcoat for a thermo-printable tape with a smooth printable surface includes a polymer blend, a crosslinker, a pigment, and a solvent. In one or more embodiments, the polymer blend includes a polyether polyurethane, a vinyl copolymer, and an epoxy polymer. In one or more embodiments, a thermo-printable tape with a smooth printable surface includes a topcoat layer, a basecoat layer, and a base substrate. In one or more embodiments, a topcoat layer is disposed on the basecoat layer. The basecoat layer is disposed on the base substrate. In one or more embodiments, the base substrate may include a first base layer, a second base layer and a support layer between the first and second base layers. One or more embodiments include a method of forming a thermo-printable tape.
Claims29
A thermo-printable tape comprising:
- a base substrate having a first side for attaching to a fabric substrate and a second side opposite the first side, the base substrate including a thermoplastic polyurethane;
- a basecoat layer disposed on the second side of the base substrate, the basecoat layer including an at least partially crosslinked polyurethane;
- and
- a topcoat layer being disposed on the basecoat layer, the topcoat layer having a polymer network with polyurethane crosslinks formed from at least two of a polyurethane, a vinyl and an epoxy polymer, the topcoat layer having a smooth printable surface with a roughness of at most 50 μin without calendaring as measured by a profilometer per ASME B46.1.
A topcoat composition for a thermo-printable tape comprising:
- about 20 to 90% by weight of a polymer blend, the polymer blend including at least two of a polyether-based polyurethane, a vinyl, and an epoxy polymer;
- about 1 to 25% by weight of a polyisocyanate crosslinker;
- about 5 to 60% by weight of titanium dioxide;
- and
- solvent;
- wherein upon curing, the topcoat composition forms an at least partially crosslinked coating having a smooth printable surface with a roughness of at most 50 μin without calendaring as measured with a profilometer per ASME B46.1.
A method for forming a thermo-printable tape comprising:
- providing a base substrate having a first side for bonding to a fabric substrate and a second side opposite the first side;
- applying a wet basecoat layer including a first polyisocyanate crosslinker to the base substrate;
- curing the wet basecoat layer to form a dry basecoat layer bonded to the base substrate;
- applying a wet topcoat layer to the dry basecoat layer, the wet topcoat layer including a second polyisocyanate crosslinker and polymer blend having at least two of a polyether-based polyurethane, a vinyl having a hydroxyl content of less than 10% by weight of the vinyl, an epoxy polymer;
- and
- curing the wet topcoat layer to form a dry topcoat layer bonded to the dry basecoat layer wherein the polymer blend and second polyisocyanate crosslinker form an at least partially crosslinked polymer network.
A topcoat composition for a thermo-printable tape comprising:
- about 20 to 90% by weight of a polymer blend, the polymer blend including at least two of polyether-based polyurethane, a vinyl, and an epoxy polymer;
- about 5 to 60% by weight of titanium dioxide;
- and
- about 5 to 60% by weight of a solvent;
- wherein the topcoat composition when mixed and cured with a polyisocyanate crosslinker forms a dry topcoat layer having an at least partially crosslinked polymer network.
