Neutral moisture curable organopolysiloxane compositions are prepared from silanol-stopped organopolysiloxanes, alkoxysilanes, aminosilanes, and ketoximino silanes, and contain less than 1 weight percent oximes upon storage.

Process for producing compositions crosslinkable to elastomers

Moisture curable elastomer compositions are highly suitable for use as sealants, and initially contain an organopolysiloxane having condensable groups, a tri-acyloxy functional organosilicon compound, and as fillers, anhydrite and silica. The compositions have very low modulus and accommodate high joint movement, while being storage stable.

Self-adhesive hardener composition

Materials crosslinkable at room temperature by condensation are based on organosilicon compounds which cure to give permanently resilient materials, and which employ one or more compounds of the metals Li, Na, K, Mg, Ca, or Sr as catalyst.

Condensation-crosslinking silicone materials

Materials crosslinkable at room temperature by condensation, based on organosilicon compounds which cure to give permanently resilient materials, are catalyzed by a compound of the main or subgroups I and II in conjunction with an inorganic acid as a catalyst.

Silicone materials which crosslink by condensation at room temperature

The present invention relates to substances, crosslinkable by attachment of an Si-bonded hydrogen atom to an aliphatic multiple bond, which comprise at least one compound of the formulaRP(O) (OH)&#x2003;&#x2003;(III)and/or the derivatives thereof,

Process for the preparation of crosslinkable materials based on organosilicon compounds

The present invention relates to compositions which crosslink to give elastomers, which are based on component (A) comprising polyorganosiloxane (I) having at least two alkenyl groups per molecule, at least one hydroxyl-group-containing compound and a metallic catalyst (V) and component (B) comprising polyorganosiloxane (II) having at least two silicon-bonded hydrogen atoms and organic sulfur compound (VI).

RTV-2 silicone foams with low compression set

Compositions which are storable under anhydrous conditions, but when exposed to atmospheric moisture crosslink at room temperature to form elastomers comprising a diorganopolysiloxane having one Si-bonded hydroxyl group in each of its terminal units, and a cyclic silane of the formula ##STR1## where R represents a divalent hydrocarbon radical, R.sup.1 represents the same or different monovalent hydrocarbon radicals, which can be substituted by an alkoxy group, and R.sup.2 represents hydrogen or an alkyl or aminoalkyl radical in which the silicon atom of the cyclic silane is bonded to a nitrogen atom and to two monovalent hydrocarbon radicals, which can be substituted with an alkoxy group via oxygen and to a hydrocarbon radical via carbon.
