Abstract:
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

Flowable methyl isothiocyanate (I) compsn. comprises 25-75 wt.% highly absorbant silicic acid support and 75-25 wt.% (I), opt. together with other nemotocides and/or fungicides. The compsn. is pref. formed into tablets or pellets.
Abstract:
An anti-foaming agent is produced by mixing organosiloxane polymers with a micronized alkalized silica and this mixture is homogenized, heated and then homogenized once more. The anti-foaming agent may be used in the varnish industry, in paper making and size production, in surface defoaming of mineral oils, in detergent formulae, in steam boilers when boiling bitumens, in the processing of colour printing pastes and, for example, in the production of amino acids.
