Definitions
- the present invention relates to a new method for curing free-radically curable compositions under a protective gas atmosphere.
- the present invention also relates to a device for carrying out the new method.
- compositions that can be radically hardened with radiation have numerous advantages. So they can be processed as 100% systems without water or organic solvents. When cured, heat-sensitive substrates are generally not damaged. However, radiation curing can strongly inhibit curing or polymerization by oxygen. This inhibition leads to incomplete hardening of the masses on the surface, which results, for example, in sticky or non-scratch-resistant coatings.
- the new method should no longer have the disadvantages of the prior art, but should in all cases provide in a simple manner completely free-radically hardened compositions, in particular coatings, which show the desired application properties profile, in particular a particularly high scratch resistance.
- the new method is intended to allow the radically curable compositions to be irradiated at a constantly low oxygen concentration without the protective gas atmosphere being swirled.
- the new device should allow the radically curable compositions to be immersed and immersed in the protective gas atmosphere without causing turbulence during the irradiation and contamination of the protective gas atmosphere by oxygen, so that the radiation can be carried out at a constantly low oxygen concentration.
- the new device should allow the distance between the radiation sources and the free-radically curable materials to be varied, so that the optimum distance is guaranteed in all cases.
- the radiation sources should not come into contact with the protective gas atmosphere in order to prevent turbulence from the outset.
- the new device should make it possible to irradiate the radically curable compositions one after the other or simultaneously with different radiation sources.
- the new device (1) for carrying out the method according to the invention comprising an immersion station (1.2) open or open at the top and filled with a protective gas atmosphere (1.4), comprising a gas-tight bottom (1.9), three gas-tight side walls (1.3 ), a gas-tight side wall (1.3.1) and - a protective gas / air interface (1.4.1), in which the lowest oxygen concentration in the protective gas atmosphere (1.4) is constant from a depth (1.4.2);

- the device according to the invention allowed the radically curable compositions to be immersed and immersed in the protective gas atmosphere without causing turbulence during the irradiation and contamination of the protective gas atmosphere by oxygen, so that the radiation could be carried out at a constantly low oxygen concentration.
- the new device made it possible to vary the distance between the radiation sources and the radically curable materials, so that the optimum distance was guaranteed in all cases. The radiation sources did not come into contact with the protective gas atmosphere, so that turbulence could be excluded from the outset.
- the device according to the invention made it possible to irradiate the free-radically curable compositions one after the other or simultaneously with different radiation sources.

- the hardening results in free-radically hardened, in particular thermosetting, masses which are composed of a three-dimensional network.
- the free-radically curable compositions contain bonds which are associated with radiation, ie electromagnetic radiation, such as IR radiation, NIR radiation, visible light, UV radiation, X-rays and gamma radiation, in particular UV radiation, and corpuscular radiation, such as electron radiation, alpha radiation, beta radiation.
