Abstract
Adhesive film strip for a temporary bond which can be detached without residue and without damage by pulling in the direction of the bond plane, having a layer structure comprising an elastic backing layer which is provided on one or both sides with an adhesive layer, characterized in that both the backing layer and the adhesive layer(s) comprise styrene block copolymers as base polymers, blended with tackifier resins which are compatible with the elastomer block of the styrene block copolymers used.
Claims34
An adhesive film strip for a temporary bond which can be detached without residue and without damage by pulling in the direction of the bond plane, said adhesive film strip having a multi-layer structure comprising an elastic backing layer which is provided on both sides with an adhesive layer, wherein both the backing layer and the adhesive layer(s) are composed of chemical compositions comprising styrene block copolymers as base polymers, which styrene block copolymers are blended with tackifier resins which are compatible with an elastomer block of the styrene block copolymers used, but wherein the chemical composition of the backing layer is different from the chemical composition of the adhesive layers.
An adhesive film strip for a temporary bond which can be detached without residue and without damage by pulling in the direction of the bond plane, said adhesive film strip having a multi-layer structure comprising an elastic backing layer which is provided on one or both sides with an adhesive layer, and a diffusion barrier between said backing layer and at least one of said adhesive layer(s), wherein both the backing layer and the adhesive layer(s) are composed of chemical compositions comprising styrene block copolymers as base polymers, which styrene block copolymers are blended with tackifier resins which are compatible with an elastomer block of the styrene block copolymers used, but wherein the chemical composition of the backing layer is different from the chemical composition of the adhesive layer(s).
