A universal slip and levelling additive having a recoatable or reprintable property contains polyoxyalkylene-polysiloxane copolymers of general formula (I)

Universal slip and flow control additives with recoatable quality

A solvent-free composition contains the following components: 2,4,7,9-tetramethyl-5-decyne-4,7-diol, ethoxylates thereof, and polyethylene glycols, wherein the composition contains water and wherein the concentration of 2,4,7,9-tetramethyl-5-decyne-4,7-diol is greater than 40% by weight, based on the composition.

Solvent-free composition based on 2,4,7,9-tetramethyl-5-decyne-4,7-diol

The invention provides hydroxyl-containing surfactants with low surface tension and provides for their use as surfactants in aqueous coating formulations, the surfactants being preparable by reacting one or more epoxides of formula (I) with at least one hydroxy compound of formula (II) and/or at least one, or two or more, amine(s) of formula (III) reacted in preferably either approximately equivalent amounts of hydroxy and/or amino groups with epoxide groups, or with an excess of hydroxy or amine hydrogen atoms, respectively.

Hydroxyl-containing surfactants with low surface tension and their use thereof

The invention relates to compound antifoams comprising alkoxylated partial esters--using from 3 to 60 mol of propylene oxide with or without from 1 to 10 mol of styrene oxide and/or from 1 to 10 mol of butylene oxide--of oligoglycerols, obtainable by condensation of 2 to 20 glycerol molecules, with C.sub.8 to C.sub.22 fatty acids and inorganic or organic solids for defoaming polymer dispersions and aqueous coating systems.

Compound antifoams for defoaming polymer dispersions and aqueous coating

Aqueous and radiation-curable printing varnishes and printing inks, are disclosed which contain special polyoxyalkylene polysiloxane copolymers. These printing varnishes and printing inks have improved scratch resistance, a higher gliding ability and an extremely low tendency to foam, so that the production of printing inks proceeds without problems and, at the same time, an optically attractive typography can be obtained.
