Title:
PRESSURE-SENSITIVE ADHESIVE TAPE FOR CORROSION PREVENTION, STRUCTURE, AND CORROSION PREVENTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/058185
Kind Code:
A1
Abstract:
This pressure-sensitive adhesive tape for corrosion prevention comprises a substrate and a pressure-sensitive adhesive layer disposed on at least one surface of the substrate, wherein the substrate has a difference between the tensile load at 2.5% elongation and the tensile load at 0.5% elongation of 1.5-6.0 N/mm and the substrate, when examined by the Elmendorf tearing method according to JIS K7128-2 (1998) without slitting, has a tear strength of 1.7 N or greater. This structure comprises the pressure-sensitive adhesive tape for corrosion prevention and an adherend made of a metallic material or an adherend made of concrete, the pressure-sensitive adhesive tape for corrosion prevention having been applied to a surface of the adherend. This corrosion prevention method comprises a first step, in which the pressure-sensitive adhesive tape for corrosion prevention is prepared, and a second step, in which the pressure-sensitive adhesive tape for corrosion prevention is applied to an adherend and a surface-protecting film is then removed from the pressure-sensitive adhesive tape for corrosion prevention. The present invention can provide: a pressure-sensitive adhesive tape for corrosion prevention which has excellent adhesiveness to adherends having complicated surface shapes and can be inhibited from creasing, lifting, or tearing when applied over large areas; a structure including the pressure-sensitive adhesive tape for corrosion prevention; and a corrosion prevention method in which the pressure-sensitive adhesive tape for corrosion prevention is used.
