Problems solved by technology

However, polyolefin-based adhesives and rubber-based adhesives are known to have poor adhesion to general substrates (e.g., polyester substrates, polyolefin substrates) (“adhesion to substrates” Hereinafter sometimes simply referred to as "anchoring")

Embodiment approach

[0108] The adhesive tape of the present invention may assume any of a form in which a long tape is wound into a roll, a form in which cut pieces of a long tape of an appropriate size are stacked.

[0109] The adhesive tape of the present invention may have a release agent layer to protect the adhesive layer. For example, the adhesive tape of the present invention may have a release agent layer on the substrate on the side opposite to the adhesive layer (ie, "adhesive layer / substrate / release agent layer" configuration). In this configuration, the release agent layer is sometimes referred to as a back coating, and the adhesive tape is sometimes referred to as an adhesive tape with a back coating.

[0110] In order to protect the adhesive layer of the adhesive tape of the present invention, a release material having a release agent layer formed on its base material may be used. Specifically, by bringing the adhesive layer of the adhesive tape of the present invention into contac...

Abstract

The present invention provides an adhesive tape for surface protection, comprising a substrate and an adhesive layer laminated on at least one surface of the substrate, wherein the adhesive layer is made of an adhesive comprising a polyolefin (a), a hydroxyl group-containing polyolefin (b) and a crosslinking agent (c) having a functional group capable of reacting with the hydroxyl group.

Description

technical field [0001] The present invention relates to an adhesive tape (hereinafter sometimes simply referred to as "adhesive tape for surface protection") for adhering the tape to an adherend so as to protect the surface of the adherend and when protection is no longer required Use to remove it from an adherend. Background technique [0002] It is a well-known practice to bond surface protection adhesive tapes to adherends (e.g., steel and other metal panels, molds thereof, coatings for mobile phones, etc., and painted aircraft, electric trains, automobiles, bicycles and Its components, etc.) to protect the surface of the adherend during transportation, storage, curing, and execution of work. Such an adhesive tape for surface protection is removed from the adherend after completing its role as a protectant. [0003] The adhesive tape for surface protection does not necessarily undergo a phenomenon in which part or all of the adhesive layer remains on the surface of the ...
