For example, the functionalized oligodimethylsiloxane does not have more than 20, for example, not more than 10 terminal or side functionalizing residues.

Dynasylan® 1146 – Hydrophobic Diaminofunctional Silane (55 lb. Pail)

Furthermore, the following is true: The functionalizing residue comprises as functionalization one or more residues, e. Those cases are exemplary in which an alkyl residue of dialkylketoxime stands for a methyl residue and the other alkyl residue of the dialkylketoxime for a methyl- ethyl- n-propyl- or for an iso-butyl residue.

The one- dynasylna two-component silicone formulation according dynasy,an claim 1wherein the functionalized oligodimethylsiloxane has one of the two following general formulas.

The bridge residue can be, e. The formulation of moisture-hardening RTV silicones that contain functional silanes, for example, tri- and tetra-functional silanes as cross-linkers is used. Examples are cited in the following.

Exemplary fillers are calcium carbonates, calcined caolines, carbon black, highly dispersed silicic acids and flame-retardant fillers such dynasy,an hydroxides or hydrates, for example, hydroxides or hydrates of aluminum, for example, aluminum trihydroxide.

RTV-silicones, two-part urethanes, silylated urethanes, MS polymers, and two-part dynasylxn to inorganic surfaces, plastic surfaces, and inorganic fillers.

The information presented here was acquired by UL from the producer of the product or material or original information provider.

The functionalized oligodimethylsiloxane ddynasylan at least one terminal or side functionalizing residue. The one- or two-component silicone formulation according to claim 1wherein the polydiorganosiloxane is a hydroxy-terminated polydimethylsiloxane.

The one- or two-component silicone formulation according to claim 1wherein the silicone formulation is a two-component silicone formulation, wherein the first component as polymer component A comprises the at least one polydiorganosiloxane and the second component as hardener component B comprises the at least one oligomeric siloxane and the at least one functionalized dnyasylan.

According to one aspect, a one- or two-component silicone formulation is provided, 1164. The one- or two-component silicone formulation according to claim 1wherein the oligomeric siloxane is a condensation product of one or more monomeric silane cross-linkers and the monomeric silane cross-linker is a silane compound with three or more functional residues selected from at least one of alkoxy residues, acetoxy residues, oxime residues, amino residues, or N-methylamido residues.

The silicone formulation according to the disclosure concerns a one- or two-component formulation, i. The storage was halted after 6 months when no phase separation was able to be observed up to then.

Silicones are compositions which have been used as adhesives or sealants. The index m can be selected in such a manner that the polydiorganosiloxane has the viscosity indicated in the following.

Examples for such functional residues of polydiorganosiloxane which are, for example, terminal functional residues are hydrido- hydroxy- vinyl- alkoxy- acetoxy- and ketoxime residues, wherein hydroxy residues are exemplary. The polydiorganosiloxanes are cross-linkable polydiorganosiloxanes.

EP-A relates to the production of poly 3-aminopropylorganosiloxanes and refers to the possible use in coatings and dynasylaan. According to another aspect, a silicone component is provided, comprising:. It is apparent from these tables that functional oligomeric siloxanes show phase separation after mixing with silicone oils and that the properties of a corresponding silicone formulation become poorer after storage.

Two-component silicone formulations are condensation-cross-linking RTV 2 systems and addition-cross-linking RTV 2 systems, wherein according to the disclosure, condensation-cross-linking two-component silicone formulations are exemplary as two-component systems. The oligomeric siloxane as cross-linker is a condensation product of one or more such monomeric silane cross-linkers. The scope of the invention is indicated by the appended claims rather than the foregoing description and all dyjasylan that come within the meaning and range and equivalence thereof are intended to be embraced therein.

This took place by a careful drawing of the adhesive and by placing a cut vertically to the direction of drawing up to the clean base. The bridge residue can also be, e. As previously explained, mixtures of oligomeric silane cross-linkers with silicone oils display phase separation dynasykan a short time and are therefore not stable in storage, which is associated with other disadvantages.

As already explained, the structure of the oligomers formed can be complicated. The percentage data refers to the amount of the cohesion break. Vinylmethylmethoxysilyl- terminated Functionalized poly dimethylsiloxaneFunctional oligodimethyl- Ex.

The one- or two-component silicone formulation according to claim 1wherein the degree of condensation of the functionalized oligodimethylsiloxane is in the range of 10 to This can be, for example, a linear functionalized oligodimethylsiloxane. This is accompanied by changed qualities of the formulated RTV silicones such as reduced reactivity and reduced adhesion.

Mixtures 116 these oligomers with silicone oils display phase separation after a short time and are therefore not stable in storage. A method of using dynasglan one- or two-component silicone formulation according to claim 6comprising mixing the polymer component A with the hardener component B. However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product or material selection information is validated with the manufacturer.

The adhesive remaining after the drawing-off of the silicone on the base is evaluated cohesion break.

The one- or two-component silicone formulation therefore furthermore comprises a functionalized oligodimethylsiloxane.

Oligomeric siloxanes are used in 2-component silicone formulations as cross-linkers usually substantially only in the hardener component and can be there in amounts of 0. Exemplary functionalizing djnasylan are residues with the formula 1 R F -alkyl- the formula 2 R F -alkyl-Si R S 2 —O—, the formula 3 aminoalkylaminoalkyl and the formula 4 aminoalkylaminoalkylaminoalkyl, wherein in the formulas 1 to 4 R F is selected from mercapto, glycidoxy, amino e.
