Document Type and Number:
WIPO Patent Application WO/2017/166116
Kind Code:
A1
Abstract:
The present invention provides a structural adhesive tape, the structural adhesive tape comprising: a first adhesive layer for adhering to an adhered object and comprising a first adhesive, the surface of the first adhesive layer adhering to the adhered object being a first surface; a substrate disposed on the side of the structural adhesive tape furthest from the adhered object; and a second adhesive layer disposed between the first adhesive layer and the substrate. The second adhesive layer comprises a second adhesive and foam particles distributed in the second adhesive, and the surface of the second adhesive furthest from the substrate is a second surface. A portion of the foam particles extends from the second surface into the first adhesive layer, wherein the total cross-sectional area of the portion of the particles along the second surface is at least 20% of the area of the second surface, and the total cross-sectional area of the portion of the particles along the first surface is at most 15% of the area of the first surface. The structural adhesive tape of the present invention resolves the issue found in conventional adhesive tape of severe fluctuations in adhesiveness after activation of foam particles.
