Abstract
Provided is a water stopping tape having excellent workability. The water stopping tape includes a substrate layer, a pressure-sensitive adhesive layer that is located on the substrate layer, and a swelling layer that is located on the substrate layer together with the pressure-sensitive adhesive layer and has at least one kind of deformation assisting structure selected from the group consisting of a groove and a cut.
Claims7
A water stopping tape comprising:
- a substrate layer;
- a pressure-sensitive adhesive layer that is located on the substrate layer;
- and
- a swelling layer that is located on the substrate layer together with the pressure-sensitive adhesive layer and has at least one kind of deformation assisting structure selected from the group consisting of a groove and a cut.

A water stopping tape comprising:
- a substrate layer;
- a pressure-sensitive adhesive layer that is located on the substrate layer;
- and
- a swelling layer that is located on the substrate layer together with the pressure-sensitive adhesive layer,
- wherein in a case where L1 represents a load necessary for causing a displacement of 1 mm in a 3-point bending test in which a load acting toward the swelling layer from the substrate layer is applied to a first measurement point, and L2 represents a load necessary for causing a displacement of 1 mm in a 3-point bending test in which a load acting toward the swelling layer from the substrate layer is applied to a second measurement point, L1 and L2 satisfy a relationship of L1 < L2.
