Monomeric silane cross-linkers and also oligomeric condensation products of them are cross-linkers for silicone formulations. According to another aspect, a silicone component is provided, comprising:. The one- or two-component silicone formulation according to claim 1wherein the 146 oligodimethylsiloxane is contained in an amount of 0.

The index m can be, e.

In the previous examples alkyl or alkoxy can be, e. Other examples are tetramethoxysilane, tetraethoxysilane and tetrapropoxysilane. For example, the functionalized oligodimethylsiloxane does not have more than 20, for example, not more than 10 terminal or side functionalizing residues. R 3 can be H or alkyl.

The presently disclosed embodiments are therefore considered in all respects to be illustrative and not restricted.

As was previously explained, such polydimethylsiloxanes can be modified by the partial inclusion of other residues such as phenyl instead of methyl.

It can be advantageous to use a mixture of different fillers. The float glass panes were previously degreased with isopropanol.

The one- or two-component silicone formulation according to claim 1wherein the degree of condensation of the functionalized oligodimethylsiloxane is in the range of 5 to The reaction between the functional residue of the polydiorganosiloxane and of the functional residue of the cross-linker can take place by a condensation reaction. The functionalized oligodimethylsiloxane is present, for example, in the same component as the oligomeric siloxane.

As a result of this, customers are given the best possible support in the areas of research, applied technology, and handling. Self-adhering polyorganosiloxane elastomer compositions and method for preparing same. The disclosure relates to one- or two-component silicone formulations, for example, RTV silicones and their usage and to a corresponding silicone component.

The polymer component used for the test has the following composition:.

The functionalizing residue can be a non-hydrolysable residue. Furthermore, silicone formulations with a higher flash point and therefore with improved work safety can be formulated. The information presented here was acquired by UL 11446 the producer of the product or material or original information provider. In a one-component silicone formulation, the one component contains the polydiorganosiloxane, the 11446 siloxane and the functionalized oligodimethylsiloxane.

A silicone component, comprising: The number of functional residues in the oligomer can vary according to the degree of condensation, the type of condensation and the monomeric silane cross-linkers used but is at least 2, e.

The one- or two-component silicone formulation according to claim 1wherein the functionalized oligodimethylsiloxane is a linear functionalized oligodimethylsiloxane. Thermoconductive filler, thermocoductive silicone elastomer composition, and semiconductor devices.

The oligomeric siloxane can be formed, e. The functionalized oligodimethylsiloxane can be present in an amount of 0.

As already explained, the structure of the oligomers formed can be complicated. R 2 is independently of each other alkyl, for example, methyl, hydroxy, alkoxy, such as methoxy or ethoxy, alkyldimethylsilyloxy, alkylmethylalkoxysilyloxy or alkyldialkoxysilyloxy. The advantage of such oligomeric compounds is, among other things, a distinct reduction of the low-molecular cleavage products that become free during the hardening reaction and therefore of the VOC emissions.

Thus, it will be appreciated by those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. Exemplary ketoxime residues are dialkylketoxime residues whose alkyl residues have 1 to 6 C atoms. R 1 is independently of each other a functionalizing residue selected from a residue with the formula 1 R F -alkyl- the formula 2 R F -alkyl-Si R S 2 —O—, the formula 3 aminoalkylaminoalkyl, or the formula 4 aminoalkylaminoalkylaminoalkyl, wherein in the formulas 1 to 4R F is selected from mercapto, glycidoxy, amino, amido, methacrylato, carbamato, isocyanato or polyalkylene glycol; and R S is independently of each other C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy.

The storage was halted after 6 months when no phase separation was able to be observed up to then.
