Abstract: A platinum-catalyzed composition along with a process for producing the same and a shaped body or products made from the same. The platinum-catalyzed composition is crosslinkable by a hydrosilylation reaction. The composition includes strong acids (S) having a pKa of <2.5 is less than 0.3 ppm by weight The platinum catalysts are those having the formula R13Pt{CpR25} wherein Cp is the cyclopentadienyl radical and R1 may be identical or different and is a monovalent, optionally substituted, aliphatically saturated hydrocarbon radical. R2 may be identical or different and is a hydrogen atom, SiC-bonded silyl radical or a monovalent, optionally substituted hydrocarbon radical.

Abstract: Defoamer compositions containing a plurality of defined organopolysiloxanes exhibit very short initial foam collapse and yet exhibit long lasting defoaming activity when added to aqueous media prone to foaming.

Abstract: Curable silicone rubber compositions of high viscosity can be ballistically printed if the melt flow index is within a defined shear thinning range and the viscosity is also within a defined range.

Abstract: Textile fabrics are rendered water repellent yet breathable by impregnating with an organopolysiloxanes of the formula R13SiO[SiR1(OR2)O]x[SiR12O]y[SiR1R3O]zSiR13??(I).

Abstract: Cyclopentadienyl platinum complexes bearing ethylenic unsaturation are efficient photocatalysts for hydrosilylation of compounds containing aliphatic carbon-carbon multiple bonds, while exhibiting extended dark time, and are particularly useful in addition-curable organopolysiloxane compositions.

Abstract: Hardener compositions for condensation-crosslinking RTV-2 systems free of organotin compounds contain a catalyst selected from among compounds of titanium, cerium, zirconium, molybdenum, manganese, copper, zinc, bismuth, lithium, strontium, or boron, and at least one aminoalkyl alcohol reinforcing the effectiveness of the catalyst.

Abstract: Moisture curable one-component organosilicon compositions exhibiting excellent resilience and adhesiveness contain an ?-alkoxysilyl-terminated base polymer, aminoalkylalkoxysilane adhesion promoter, and polyolefin bearing succinic anhydride groups.

Abstract: Silicone foams having good foam structure and rapid cure are produced from foamable mixtures containing a physical blowing agent and an organically modified organopolysiloxane containing at least one urea or urethane group and an alkoxy(alkyl)siloxy unit.

Abstract: In the preparation of aminoorganylsilanes and cyclic aminosilanes by reaction of an organyl amine with a haloorganylsilane, the byproduct halide salt of the amine reactant is decomposed to amine by addition of a base whose halide salt forms a liquid phase at a temperature below 200° C., and the liquid base halide is separated from the reaction mixture.

Abstract: Undesired polymerization of (meth)acrylatoalkoxysilanes during their industrial preparation and handling is accomplished by avoiding contact with surfaces containing more than 1% by weight of iron.
