Abstract
The invention relates to a method for producing an adhesive bond by means of an adhesive, wherein a composition containing at least a substance reactive in a radical polyreaction and a catalytically active substance is used as the adhesive, wherein at least one metal complex from the group of the metal phthalocyanines and/or from the group of the metal porphyrins is selected as the catalytically active substance, wherein a polyreaction of the reactive substance occurs, which polyreaction is initiated by the application of a plasma.
Claims20
A method comprising:
- providing an adhesive agent comprising an adhesive comprising at least one reactive substance and at least one catalytically-active substance;
- applying the adhesive agent between a first substrate and a second substrate;
- and
- exposing the at least one reactive substance to a plasma, thereby causing the at least one reactive substance to undergo a polymerization reaction,
- wherein:
- the at least one catalytically-active substance comprises a first substance selected from the group consisting of a metal phthalocyanine, a metal porphyrin, or a metal phthalocyanine and a metal porphyrin;
- and
- the polymerization reaction initiates curing of the adhesive.
5 more elements
An adhesive agent comprising an adhesive comprising:
- at least one reactive substance capable of reacting in a radical polymerization reaction upon exposure to a plasma;
- and
- at least one catalytically-active substance,
- wherein:
- the at least one catalytically-active substance comprises a second substance selected from the group consisting of a metal phthalocyanine, a metal porphyrin, or a metal phthalocyanine and a metal porphyrin;
- and
- the radical polymerization reaction can be initiated by the plasma.
