Abstract: The invention relates to a silane/filler preparation, consisting essentially of from 5 to 70% by weight of at least one silane corresponding to the following formula Xp-CmH2m+1-pSiRn1(OR)3-n, I in which X=a halogen atom, preferably chlorine or bromine, p=1 or 2, m=1 to 5, R1=a C1-C5 alkyl group, C5-C8-cycloalkyl group or a phenyl group, R=a C1-C5-alkyl group, a C5-C8-cycloalkyl group, a phenyl group, a benzyl group or a C1-C5-alkoxy-C1-C5-alkyl group, and n=0, 1 or 2, and-respectively balanced to 100%-from 95 to 30% by weight of at lesat one inorganic filler, preferably carbon black and silicate fillers as, e.g., silica. There is also disclosed a process for the production of the silane/filler preparation and its use in optionally cross-linkable polymeric moulding compositions or vulcanizable or cross-linkable rubber moulding compositions such as sulphur-vulcanizable moulding compositions based on natural rubber and/or synthetic rubber.

Abstract: Deeply colored carbon black having a low content of extractable matter and a primary particle size of about 8-25 nanometers is made by the gas black process using as the carrier gas for the vapors of the carbon black forming oil a hydrogen rich mixture containing over about 50 volume % hydrogen and then collecting the separated carbon black deposited on a cooling roll.

Abstract: The present invention provides a granular organosilane preparation composed of a) from 30 to 60% by weight of one or more organo-silanes corresponding to the formula in which R1 represents a monovalent alkyl radical containing from 1 to 3 carbon atoms, R2 represents a monovalent alkyl radical or alkoxy radical containing from 1 to 3 carbon atoms, R represents a divalent alkyl radical containing from 1 to 5 carbon atoms and x represents a value from 2.0 to 6.0, andb) from 70 to 40% by weight of one or more carbon blacks. The preparations have good storage stability, stability against hydrolysis and ease of working into rubber mixtures.

Abstract: A black-pigmented, UV-hardening printing ink which contains for its black pigmentation, a carbon black having the following physical-chemical characteristic data: BET surface area 20-50 sq m/g particle diameter 30-80 nm DBP adsorption 30-11 ml/100 g volatile components 3-10 pH value 3-6 The printing inks are not completely cured even on storage for six months. They dry extremely fast and thus result in prints fast to wiping.
