The present disclosure provides for a repair device useful in the repair of surfaces, particularly in a healthcare environment. An exemplary form of the present comprises a repair patch, a pre-mask and release liner; the repair patch interposed between the pre-mask and release liner; the removable adhesive interposed between the pre-mask and repair patch; and the permanent adhesive interposed between the repair patch and the release liner; wherein the adhesion value of the removable adhesive is lower than that of the permanent adhesive.

Surface repair patch and method of using same

A release coating having improved stability under aging conditions of heat and humidity is described whose release force can be altered by varying the amount of multi-lobe emulsion polymers relative to release agent.

Release coating and process

A method for preparing a pressure sensitive paper label is provided. The method is particularly useful on filled papers, especially papers filled with inorganic fillers containing multivalent cation. The pressure sensitive adhesive contains from 0.1 percent to 5 percent of a selected acid monomer, and 99.9 percent to 95 percent of at least one ethenically unsaturated monomer. Paper labels made by the method of this invention have superior age-resistance properties, and may be applied to a wide variety of substrates such as paper, metal, glass, wood, painted surfaces, corrugated board and plastic.
