Abstract: A composition crosslinkable by condensation reaction and producible using (A) organopolysiloxanes of the formula (R2O)3-aSiR1aO(SiR2O)nSiR1a(OR2)3-a (I), (B1) silanes of the formula R34-b(R4O)bSi (II), and optionally (B2) silicon compounds consisting of units of the formula R7c(R8O)dSiO(4-c-d)/2 (III). The composition contains organosilicon compounds having a molecular weight of less than or equal to 195 g/mol maximally in amounts of less than 0.5 wt%, based on organopolysiloxane (A).

Abstract: Crosslinkable compositions, processes for producing the same and products made therefrom. Where the crosslinkable compositions include a component (A) organosilicon compounds having at least two silanol groups and having a viscosity of 103 to 106 mPas at 25° C., mixtures (M) containing a component (B) of organosilicon compounds of the formula (I) and/or partial hydrolyzates thereof R6R7N—CR12SiRa(OR2)3-a??(I), a component (C), selected from (C2) compounds of the formula (III) R5OH??(III). The crosslinkable compositions may optionally also include a catalyst (D).

Abstract: A crosslinkable composition is based on organosilicon compounds that include (A) organopolysiloxanes of the formula (I), the formula (I) being (R7O)3-aSiR3aO(SiR42O)nSiR3a(OR7)3-a, and (B) siloxanes of the formula (II), the formular (II) being with the proviso that the sum of all x in formula (II) is greater than 0.

Abstract: RTV-1 compositions are continuously produced from essentially linear organosilicon compounds having at least two condensable groups bound to silicon, filler and, optionally, further constituents, by mixing in one step in a single pass through the mixing zone of a rotor-stator mixer, wherein the pressure at the outlet of the mixing apparatus is at least 100 hPa greater than that at the inlet of the mixing apparatus.

Abstract: Crosslinkable compositions based on organosilicon compounds with a very high storage stability contain fine-particle metacarbonate. Storage stability of the composition is increased as compared to conventional forms of carbonates.
