Definitions
- the present invention relates to the field of silicone compositions.
- Silicones are known compositions which have long been used as sealants.
- One-component silicones are moisture-reactive and harden under the influence of water. It is state of the art that such silicone compositions are composed of polydiorganosiloxanes and a crosslinker.
- Acid-crosslinking silicone compositions have, for example, acyloxysilane groups which split off carboxylic acids on crosslinking.
- a disadvantage of these acid-crosslinking systems is that the smell of the carboxylic acid formed in the networking is often perceived as disturbing.
- E P-A-1 342 742 describes a polysiloxane composition which comprises acyloxysilane-terminated polysiloxanes and an alkoxysilane crosslinker.
- acidic crosslinking silicone compositions are disadvantageous because, in addition to the offensive odor, the carboxylic acid formed can cause problems when used on certain substrates, such as metals or concrete.
- such silicone compositions also have problems in storage stability.
- Neutral-crosslinking silicone compositions have, for example, alkoxysilane or ketoximosilane groups.
- Alkoxysilane-based silicone compositions have the great disadvantage that they have a shortened storage stability and certain weaknesses in the adhesion to different substrates.
- EP-A-384 609 describes a hydroxyl terminated polysiloxane which is crosslinked with alkoxy or alkoxyalkoxy silanes and compounded directly.
- such a silicone composition has some disadvantages, for example, that the hydrolysis of alkoxysilane groups is relatively slow and, compared to oxime-crosslinking silicone compositions, has a lower rate of cure, less storage stability, and weaknesses in adhesion.
- EP-A-0 543 615 describes silicone compositions which contain hydroxyl-terminated polysiloxane and, as crosslinkers, ketoximo silanes and are compounded directly. Although such silicone compositions have improved storage stability and adhesion, but have a very strong odor, which is caused by the intense odor of the ketoxime formed in the cross-linking. The large amount of ketoximes formed is also disadvantageous in that the ketoximes, in particular the frequently encountered methyl ethyl ketoxime (MEKO), are regarded as hazardous to health and consequently that such silicone compositions are classified as "Xn" according to the applicable regulations in the European Union (EU). be classified and labeled with the phrase "R40" (suspected carcinogenic effect).
- EU European Union
- alkoxy-terminated polysiloxanes in combination with alkoxysilane crosslinkers is described, for example, in DE-C-195 07 416.
- the poor adhesion and storage stability of purely alkoxy-terminated polysiloxanes is improved due to the addition of phosphorus compounds.
- the improvement is only minor and still significantly worse than the ketoxime crosslinking compositions.
- they often have major problems in the curing, which must be considered a major disadvantage, especially in thick-layered applications. Presentation of the invention

- silanes there is always the possibility that, depending on moisture and conditions, it is also possible for further siloxanes to be present in the silicone composition.
- (partially) hydrolyzed alkoxysilane or ketoximosilane components can form siloxanes by condensation reactions, which can lead to oligomeric siloxanes, in particular to dimeric or trimeric siloxanes.
- oligomeric siloxanes not only linear but also branched and cyclic oligomeric siloxanes are possible.

- the one-component system (RTV-1) has proven to be particularly preferred in which the silicone sealant and / or silicone adhesive polymerizes at room temperature under the influence of moisture, in particular of atmospheric moisture, the crosslinking being effected by condensation of SiOH groups with the formation of Si. O-Si bonds take place.
- silicone compositions have a great advantage in terms of health technology and ecology by having very little free ketoxime ( ⁇ 1%). As a result, it becomes possible to formulate label-advantageous silicone compositions, but still have the advantages of the ketoximosilane systems.

- the preparation of the ketoximosilane-terminated polydiorganosiloxane KPS02 was carried out in the same way with the difference that instead of the vinyltris (methyl-ethyl-ketoximo) silane, 5.8 parts by mass of methyl tris (methylethyl ketoximo) silanes were used.
- Comparative Example Ref. 1 was prepared analogously to the compositions B1 to B4, with the difference that a mixture of ketoximosilanes without addition of alkoxysilanes was added directly to the ⁇ , ⁇ -dihydroxy-terminated polydimethylsiloxane.
- Comparative Example Ref. 2 was prepared analogously to Comparative Example Ref. 1, with the difference that alkoxysilanes were used instead of ketoximosilanes. However, the composition gelled within a short time after the addition of the catalyst.

- the cured bead was cut in each case at one end just above the surface of the substrate (adhesive surface).
- the incised end of the caterpillar was held by hand and then gently and slowly, peeling in the direction of the other caterpillar end, pulled from the substrate. If the adhesion was so strong that the end of the caterpillar threatened to tear during pulling, a cut perpendicular to the caterpillar pulling direction was applied to the bare surface of the substrate by means of a cutter and the caterpillar was detached a little way. Such cuts were repeated, if necessary, when moving on at a distance of 2 to 3 mm. In this way the entire bead was peeled from the substrate.
- the adhesion properties were evaluated on the basis of the hardened sealant (cohesive failure) remaining on the surface of the substrate after peeling off the bead, by estimating the cohesive percentage of adhesive surface area.
- AI PB Powder-coated aluminum
- the skin formation time was measured as follows. A bead of the silicone composition was applied to a polyethylene film from a cartridge one day after the preparation of the composition and pulled out by means of a spatula to an approximately 3 mm thick layer. The surface of this caterpillar was carefully touched with your finger at regular intervals. Skin formation time was the time that had elapsed since the application of the silicone composition until the time when no silicone composition remained adhered to the finger.
- the storage stability was evaluated by comparing the skin formation time [SOT] with the skin formation time after heat storage (SOT 70- c).
- a ratio of SOT 70 -CI SOT ⁇ 2 and SOT 70 -CI SOT> 0.5 corresponds to a storage stability at room temperature of at least 6 months.
- Such silicone compositions are evaluated as "good.”
- a ratio of SOT 70 -CI SOT between 2 and 2.5 is acceptable and is termed "a / cz.” assessed. If SOT 70 - C does not differ by more than ⁇ 20% from SOT, a storage stability of more than 6 months at room temperature is to be expected and such silicone compositions are considered to be "very good.
