ABSTRACT:
The vibration damper material comprises a laminate of a viscoelastic layer and a hardenable pressure sensitive adhesive layer, and a release liner applied onto the hardenable pressure sensitive adhesive layer. The viscoelastic layer is intended to form a vibration damping layer, and contains a viscoelastic material mainly comprised of unvulcanized rubber to which a vulcanizing agent (crosslinking agent) has been added. The hardenable pressure sensitive adhesive layer comprises a hardenable pressure sensitive adhesive which has adhesive properties in the uncured state but has a strong adhesive strength when it is cured by heating, irradiation with light or by being blocked from air for example. This hardenable pressure sensitive adhesive layer contains a sticking polymer, a reactive oligomer and a polymerization initiator. The release liner which is utilized has a silicone layer formed on the surface of a base material thereof. This vibration damper material has an excellent ability to follow curved surfaces, a reliable adhesivity, and provides a high degree of vibration damping property without impairing the efficiency in the operation in which the vibration damper material is applied onto an adherend.
