Abstract

A packaging for multi-component adhesives comprises (1) a first section which contains at least three individual components of the multi-component adhesive and (2) a second section which contains at least two individual components of the multi-component adhesive. The individual components of the multi-component adhesive are distributed to the two sections in such a way that a reaction between the individual components is prevented and hardening of the adhesive takes place only after complete mixture of the individual components. This makes stable storage of the components possible.

First claim

The invention claimed is:

1. A packaging for a multi-component adhesive, said packaging comprising:
a first section which contains at least three individual components of the multicomponent adhesive,
a second section located separate from the first section which contains at least two individual components of the multi-component adhesive,
wherein the individual components of the multi-component adhesive are divided into the two sections in such a way that a reaction between the individual components is prevented and hardening of the adhesive takes place after mixing of the individual components,
wherein the first section contains
at least one radically polymerizable compound,
at least one accelerator,
at least one hardening agent for the polyaddition, and

the second section contains
at least one compound polymerizable by polyaddition, and
at least one radical initiator.

2. The packaging of claim 1 , wherein the at least three individual components of the multi-component adhesive are provided in the first section in at least two separate chambers.

3. The packaging of claim 2 , wherein
a first chamber contains
the at least one radically polymerizable compound,
optionally at least one inhibitor, and
optionally at least one compound with two functional groups, of which one can (co)polymerize radically and the other by polyaddition, and

a second chamber contains
the hardening agent for the polyaddition, and
the at least one accelerator.

4. The packaging of claim 3 , wherein the first chamber of the first section further contains at least one more reactive thinner for the radically polymerizable compound.

5. The packaging of claim 1 , wherein a mixing ratio of the first section to the second section is between 1:1 and 10:1.

6. The packaging of claim 5 , wherein the mixing ratio of the first section to the second section is 3:1 or 5:1.

7. The packaging of claim 2 , wherein a mixing ratio of the first chamber to the second chamber is between 4:1 and 1:4.

8. The packaging of claim 7 , wherein the mixing ratio of the first chamber to the second chamber is between 4:1 and 1:1.

9. The packaging of claim 1 , wherein
the at least one compound polymerizable by polyaddition is an epoxy compound,
the at least one hardening agent for the polyaddition is an amine.

10. The packaging of claim 1 , wherein the packaging is a film-wrapped pack with a first film bag and a second film bag.

11. The packaging of claim 10 , wherein a head part with at least two mounting sections for one end of the film bags is further provided on the film-wrapped pack.

12. The packaging of claim 1 , wherein the first section further contains
at least one inhibitor.

13. The packaging of claim 1 , wherein the first section further contains
at least one compound with two functional groups, of which one can (co)polymerize radically and the other by polyaddition.

14. The packaging of claim 13 , wherein the optional compound with two functional groups is a compound with two functional groups, of which one can radically (co)polymerize and the other being an epoxy group.

15. The packaging of claim 3 , wherein the first chamber contains
the at least one inhibitor.

16. The packaging of claim 3 , wherein the first chamber contains
the at least one compound with two functional groups, of
which one can (co)polymerize radically and the other by polyaddition.

17. The packaging of claim 1 , wherein the first section further contains
at least one inhibitor, and
at least one compound with two functional groups, of which one can (co)polymerize radically and the other by polyaddition.
