This invention generally relates to material used to mask a structure like a surface, and more particularly to a tape like material with select tacky adhesive area(s) and at least one non-tacky area, where the material can be torn or cut apart as it is prepared for use to cover or mask a structure like the surface of a wall, window, building or other structure.
A variety of materials have been used to cover or mask surfaces for temporary to permanent purposes. For example, there is conventional masking tape made of a creeped paper base layer and having one surface completely coated with tacky adhesive. There is also a material known as painter's tape that can be similar to the masking tape, but only an edge portion of one surface of the material is coated with tacky adhesive and the other portion of that same surface is non-tacky. However, when trying to mask a structure while also being able to more fully cover the structure with a sheeting connected to the tape material, no existing masking material can do the job. Accordingly, there is a need to address one or more of the deficiencies in the art to better aid in achieving more desirable requirements for masking materials and avoiding negative ones, especially when trying to use both a masking material and a sheet material secured thereto.
To address one or more deficiencies in the art and/or better achieve the desirable requirements for masking surfaces of a structure as taught herein, there is provided a tape to mask a structure. The tape includes a base layer having a length, a width, an outside surface, an inside surface, and a top edge spaced from a bottom edge. A first portion of the width of the inside surface of the base layer includes a first tacky adhesive layer connected to the inside surface and located adjacent the top edge. A second portion of the width of the inside surface of the base layer includes a second tacky adhesive layer connected to the inside surface and located adjacent the bottom edge. At least a portion of the base layer includes a water impermeable area that prevents water adjacent the outside surface from reaching the inside surface by passing through the base layer. And, a third portion of the width of the inside surface of the base layer includes a non-tacky area located between the first tacky adhesive layer and the second tacky adhesive layer
In another aspect, there is provided an alternate tape to mask a structure. The tape includes a base layer having a length, a width, an outside surface, an inside surface, and a top edge spaced from a bottom edge. A first portion of the width of the inside surface of the base layer includes a first tacky adhesive layer connected to the inside surface and located adjacent the top edge. A first portion of the width of the outside surface of the base layer includes a third tacky adhesive layer connected to the outside surface and located adjacent the bottom edge. At least a portion of the base layer includes a water impermeable area that prevents water adjacent the outside surface from reaching the inside surface by passing through the base layer. And, a second portion of the width of the outside surface of the base layer includes a non-tacky area located adjacent the second tacky adhesive layer.
Also described herein are aspects concerning a process, which preferably includes providing a tape having a length, a width, an outside surface, an inside surface, and a top edge spaced from a bottom edge. Another step is adhering a portion of the width of the inside surface of the tape at the top edge to the structure. And, another step is securing a cover sheet to one of the outside surface or the inside surface of the tape adjoining the bottom edge to form a cover sheet secured area. Further, there is the step preventing a second portion of the width of the tape from securing to the cover sheet by utilizing a non-tacky area in a portion of the width of the tape on a same one of the outside surface or the inside surface as the cover sheet secured area.
Other aspects of the disclosure are directed to configurations and features for the adhesive layer, adhesive free area(s), tacky and non-tacky aspects, the tape as a roll of tape, construction of the layers and Adhesion Value for certain combinations of layers
As used herein, the “Adhesion Value Test” is that set forth in industry test ASTM D3330/D3330M-04(Reapproved 2018) titled: Peel Adhesion of Pressure-Sensitive Tape, and the protocol set forth as Test Method A (Single-Coated Tapes, Peel Adhesion at 180 degree Angle) and documents referenced therein, for measuring the Adhesion Value of a layer of material (e.g., tape) having an adhesive layer connected to the layer of material, and using such Adhesion Value Test for all of the layer configurations disclosed herein when an Adhesion Value is needed.
As used herein, “connected” and formatives thereof, means a layer of adhesive joined to a layer of material such that mechanical separation of the two layers unintentionally tears at least a portion of one of the layers so joined together.
As used herein, “removably attached” means a layer of material joined to a layer of adhesive such that mechanical separation of the two layers does not substantially alter the surface of either the layer of material or the layer of adhesive and they can be attached and removed from each other at least once without substantially altering the surface of either layer.
As used herein, a “tacky adhesive layer” means a layer of adhesive that is connected to a surface of a layer of material and then that combination has an Adhesion Value of at least ten ounces/inch (Newtons/25 mm) as measured when separating the layer of material with the adhesive layer connected thereto from the stated stainless steel panel surface in the Adhesion Value Test (defined herein).
As used herein, “non-tacky” means a layer of material, with or without an adhesive layer joined to its surface, and then that combination (or just the layer of material without adhesive) has an Adhesion Value of less than ten ounces/inch (Newtons/25 mm) as measured when separating the layer of material, with or without adhesive joined thereto, from the stated stainless steel panel surface in the Adhesion Value Test (defined herein).
The invention may be more completely understood in consideration of the following detailed description of various aspects of the invention in connection with the accompanying drawings, in which:
The drawings show some but not all embodiments. The elements depicted in the drawings are illustrative and not necessarily to scale, and the same (or similar) reference numbers denote the same (or similar) features throughout the drawings, though all the same (or similar) features are not always separately numbered to help avoid over numbering and obscuring what the drawings are disclosing.
