The bondable fastener serves to hold structural or functional parts on essentially flat support elements. It consists of an adhesive-functional zone for establishing an adhesive bond with surface of the support element and at least one other holding ::one for establishing positive or non-positive connections with the structural part. The adhesive functional zone has a bonding surface that is provided with a hardenable and/or cross-linkable reactive hot-melt-type adhesive that is dry, i.e. is wearproof and non-viscous, at temperatures up to 80.degree. C and that can very quickly be reactivated to establish a permanent adhesive bond when heat or some other form of energy is applied. The hot-melt-type adhesive used for this purpose is based on specific backbone bonding agents that set and harden through polymerization, polyaddition and/or polycondensation reaction mechanisms. |
