The invention relates to a method for peeling a pressure-sensitive adhesive tape including: a pressure-sensitive adhesive layer. The pressure-sensitive adhesive tape has a thickness greater than 150 μm and smaller than 1,500 μm, an elongation at break of 600% to 3,000%, and a stress at break of 2.5 to 80.0 MPa. According to the invention, the conformity and the adhesion with respect to an adherend, particularly, a hard adherend, are excellent, and excellent re-peeling properties are obtained, so that the pressure-sensitive adhesive tape can be stretched and peeled off in a horizontal direction, without necessity for embrittling the pressure-sensitive adhesive tape by heating or by using an organic solvent or the like or without remaining of the pressure-sensitive adhesive on the adherend, in a case of peeling the pressure-sensitive adhesive tape.

Liquid epoxy-based adhesive compositions are provided, which upon curing result in crash durable and stress resistant cured bonds on both steel and other materials, in particular metals such as aluminum; and in some embodiments are weldable in an uncured state; also provided are bonded assemblies comprising the cured epoxy-based adhesives, methods of making the liquid epoxy-based adhesives, methods of bonding assemblies and articles of manufacture comprising the bonded assemblies.
