Abstract
Adhesive articles and methods of applying and activating adhesive articles to bond to substrates using a fluid application aid. Preferably, the substrates are traffic devices such as traffic cones and the adhesive articles are retroreflective cone collars or sleeves.
Claims18
A method of adhering an adhesive article to a substrate, the method comprising:
- providing an adhesive article comprising a surface on which is disposed an adhesive with a plurality of nontacky protrusions in the form of particles;
- applying the adhesive article to the substrate to form an interface between the adhesive and the substrate;
- and
- providing a fluid application aid to the interface between the adhesive and the substrate to promote adhesion between the adhesive article and the substrate, wherein the fluid application aid and the substrate each comprise a plasticizer and wherein the protrusions become tacky upon interaction with the application aid.
A method of adhering an adhesive article to a substrate, the method comprising:
- providing an adhesive article comprising a surface on which is disposed an adhesive with a plurality of protrusions in the form of particles;
- applying the adhesive article to the substrate to form an interface between the adhesive and the substrate;
- and
- providing a fluid application aid to the interface between the adhesive and the substrate to promote adhesion between the adhesive article and the substrate, wherein the fluid application aid comprises water, an organic solvent, or combinations thereof and the fluid application aid and the substrate each comprise a plasticizer.
A method of adhering an adhesive article to a substrate, the method comprising:
- providing an adhesive article comprising a surface on which is disposed an adhesive with a plurality of protrusions in the form of particles;
- applying the adhesive article to the substrate to form an interface between the adhesive and the substrate;
- and
- providing a fluid application aid to the interface between the adhesive and the substrate to promote adhesion between the adhesive article and the substrate, wherein the fluid application aid comprises a mixture of plasticizer, water and a surfactant and the fluid application aid and the substrate each comprise a plasticizer.
A method of adhering an adhesive article to a substrate, the method comprising:
- providing an adhesive article comprising a surface on which is disposed a plasticizer-activatable adhesive with a plurality of plasticizer-activatablc adhesive protrusions, the plasticizer-activatable adhesive comprising a plasticizer-activatable pressure sensitive adhesive that comprise an over-tackified adhesive;
- applying the adhesive article to the substrate to form an interface between the adhesive and the substrate;
- and
- providing a fluid application aid to the interface between the adhesive and the substrate to promote adhesion between the adhesive article and the substrate.
