Abstract: Storage stability of one-component elastomers prepared from constituents having alkoxysilyl end groups is enhanced by employing bin compounds having a coordination number of 5 or 6 in which tin is coordinately bonded to a P?O group as at least one condensation catalyst.

Abstract: The invention relates to crosslinkable compositions based on organosilicon compounds and having controllable modulus, to a process for their preparation and to their use, said compositions comprising (a) polymers of the formula XnR3-nSi-A-SiR2—(CH2)3NHY??(I) (b) polymers of the structure X1kR53-kSi-A1-SiX1kR53-k??(II) (c) optionally, silanes of the formula R6mSiX24-m??(III) and/or partial hydrolyzates thereof, and (d) optionally, silanes of the formula R4oSiR7pX34-o-p??(IV) and/or partial hydrolyzates thereof, where X, X1 and X3 are OH or a hydrolyzable group, R, R4, R5, and R7 are hydrocarbyl groups, and A is a divalent linking group.

Abstract: Alkoxysilane-terminated polymers prepared by reacting an isocyanatoalkoxysilane, preferably an isocyanatodialkyalkoxysilane, with an isocyanate-reactive prepolymer, can provide chain extension even when a monoalkoxy-functional silane, while retaining suitable reactivity profiles. The products are useful in sealants, caulks, coatings, and moldings.

Abstract: The invention relates to compounds on the basis of organosilic compounds, which can be crosslinked at room temperature, so-called RTV-1 compounds, and which are characterized by containing as the catalyst at least one organozinc compound (C) that contains moieties of the general formula (I): RaR1b(XR3)cSnX(4-a-b-c)/2, and compounds (D) that contain basic nitrogen, wherein R1 is the same or different and represents —OS(═O)2R2, and R, X, R2, R3, a, b and c are defined as in claim 1, with the proviso that the organozinc compound comprises at least one R1 group. The invention further relates to a method for producing the inventive compounds.

Abstract: Organopolysiloxane compositions obtainable by reaction of (a) essentially linear organopolysiloxanes which are terminated at both ends by Si-bonded hydroxy groups, (b) optionally, plasticizers, (c) at least one dialkylaminomethylalkyldialkoxysilane chain extender and/or partial hydrolysate thereof, (d) at least one deactivator, (e) optionally, one or more alkyltrialkoxysilanes and/or partial hydrolysates thereof, and (f) optionally, catalysts for accelerating the reaction of silane (e) with Si—OH groups, are useful in low-modulus compositions which can be crosslinked at room temperature, in particular, compositions which crosslink with elimination of alcohols.

Abstract: Storage stability of one-component elastomers prepared from constituents having alkoxysilyl end groups is enhanced by employing bin compounds having a coordination number of 5 or 6 in which tin is coordinately bonded to a P═O group as at least one condensation catalyst.

Abstract: The invention relates to alkoxy-crosslinking RTV1 silicone rubber mixtures based on polydiorganosiloxanes with dialkoxyorganosiloxy end groups, the organo radical being a substituted amidoalkyl radical, which can be prepared using conventional mixing technologies. The novel RTV1 silicone rubber mixtures cure rapidly and without tack to give products with good mechanical properties. The shelf-life of the mixtures is excellent. One particular advantage of this invention is that it is also possible to create systems in which crosslinking produces only elimination products which are completely free from toxic methanol.

Abstract: The present invention relates to a polyorganosiloxane having at least one dialkoxyorganosiloxy group, where the organo radical is a substituted amidoalkyl radical.

Abstract: The invention relates to alkoxy-crosslinking RTV1 silicone rubber mixtures based on hydroxy-terminated polydiorganosiloxanes containing a trialkoxysilane with a substituted amidoalkyl radical, which can be prepared using conventional mixing technologies. The novel RTV1 silicone rubber mixtures cure rapidly and without tack to give products with good mechanical properties. The shelf-life of the mixtures is excellent. One particular advantage of this invention is that it is also possible to create systems in which crosslinking produces only elimination products which are completely free from toxic methanol.
