Abstract
An adhesive system comprises two layers of adhesive, one layer being relatively thin and the other being optionally thicker, being separated by a permeable web. The relatively thin layer of the adhesive system provides a relatively weak initial bond between a substrate and an object to be adhered to a substrate, so that the object can be repositioned on the substrate if desired. Pressure is then applied to make the two layers of adhesive come into contact with one another through the permeable web, such that the layers function as an integral layer to provide a strong bond. The permeable web also provides tensile strength and structural support for brittle or extensible articles.
Claims37
A method of adhering an object to a substrate, comprising
- providing on a surface of said object an adhesive system comprising a) a layer of adhesive disposed against said surface, b) an adhesive-permeable web having one surface disposed against said layer of adhesive, and c) a relatively thin layer of adhesive disposed against the opposite surface of said adhesive-permeable web;
- positioning said object against said substrate such that said relatively thin layer of adhesive provides a releasable bond between the object and the substrate;
- and
- applying sufficient pressure to said adhesive system such that said layers of adhesive flow together through said adhesive-permeable web to fiction as an integral adhesive layer that provides a non-releasable bond between the object and the substrate.
A method of adhering a sheeting article to a substrate, comprising
- providing on a surface of said sheeting article an adhesive system comprising a) a layer of adhesive disposed against said surface, b) an adhesive-permeable web having one surface disposed against said layer of adhesive, and c) a relatively thin layer of adhesive disposed against the opposite surface of said adhesive-permeable web;
- positioning said sheeting article against said substrate such that said relatively thin layer of adhesive forms a releasable bond between said sheeting article and said substrate;
- applying sufficient pressure to said adhesive system such that said layers of adhesive flow together through said adhesive-permeable web to finction as an integral adhesive layer that forms a non-releasable bond between said sheeting article and said substrate.
An adhesive system for adhering an object to a substrate, said adhesive system comprising, a first layer, a second layer, and a third layer, wherein:
- a) said first layer comprises a relatively thin layer of adhesive, said thin layer providing a releasable bond between said object and said substrate, and
- b) said second layer comprises an adhesive-permeable web, and
- c) said third layer comprises adhesive, said second layer being disposed between said first layer and said third layer, such that when pressure is applied to said adhesive system, the adhesives of said first and third layers come into contact through said second layer to function as an integral adhesive layer, thereby providing between the object and the substrate a non-releasable adhesive bond.
An adhesive system for adhering a sheeting article to a substrate, said adhesive system comprising, a first layer, a second layer, and a third layer, wherein:
- a) said first layer comprises a relatively thin layer of adhesive, said relatively thin layer being sufficient to releasable secure said sheeting to said substrate,
- b) said second layer comprises an adhesive-permeable web, and
- c) said third layer comprises adhesive, said second layer being disposed between said first layer and said third layer, such that when pressure is applied to said adhesive system, the adhesives of said first and third layers come into contact through said second layer to function as an integral adhesive layer, thereby providing a non-releasable bond between the sheeting article and the substrate.
A retroreflective sheeting article comprising an adhesive system for securing the sheeting article to a substrate, said adhesive system comprising, a first layer, a second layer, and a third layer, wherein:
- a) said first layer comprises a relatively thin layer of adhesive, said relatively thin layer being sufficient to releasable secure said sheeting to said substrate,
- b) said second layer comprises an adhesive-permeable web, and
- c) said third layer comprises adhesive, said second layer being disposed between said first layer and said third layer, such that when pressure is applied to said adhesive system, the adhesives of said first and third layers come into contact through said second layer to function as an integral adhesive layer, thereby providing a non-releasable bond between the sheeting article and the substrate.
