Abstract: Crosslinkable organosilicon compositions with controllable modulus can be prepared using organosilicon compounds composed of units of the formula (HO)aRbSiO(4-a-b)/2??(I), where R is identical or different and is a monovalent, optionally substituted hydrocarbon radical optionally interrupted by heteroatoms, a is 0 or 1, and b is 0, 1, 2 or 3, with the proviso that the organosilicon compound has a single unit of the formula (I) where a=1, and has a viscosity of from 5 to 1000 mPas at 25° C.

Abstract: Crosslinkable compositions based on organosilicon compounds contain at least one compound of the formula H(OCH2CH2)n(OCHCH3CH2)p(OCH2CH2)mOH??(III) and/or a reaction product thereof with hydrolyzable organosilicon compound(s), where n is 0 or an integer from 1 to 30, m is 0 or an integer from 1 to 30, and the sum of n and m is greater than 5, and p is 1, 2, or 3. The compositions have superior application properties as compared to similar compositions without compound III.

Abstract: Aqueous dispersions organopolysiloxanes which are free of organic transition metal compounds and of organic compounds of the metals of the main groups III, IV and V. These dispersions can be produced using the following starting compounds:(A) organopolysiloxane containing condensation-capable groups;(B) an organosilicon compound of the formula{[(RO).sub.3 Si--R.sup.3 --].sub.e R.sup.2.sub.1-e }.sub.a Si(OR).sub.4-a(II),in whichR is identical or different and is a hydrogen atom or alkyl radical having 1 to 6 carbon atoms,R.sup.2 is identical or different and is an SiC-bonded hydrocarbon radical having 1 to 18 carbon atoms, optionally substituted with halogen atoms, ether groups, ester groups, epoxy groups, mercapto groups or (poly)glycol radicals comprised of oxyethylene units, oxypropylene units and mixtures thereofR.sup.3 is identical or different and is a divalent hydrocarbon radical,a is 0 or 1, ande is 0 or 1 where {[(RO).sub.3 Si--R.sup.3 --].sub.e R.sup.2.sub.1-e }.sub.
