Answer: Compared with the solvent such as ethyl acetate, methyl ethyl ketone, acetone, etc. classically used the dispersions and emulsions are incompatible, that means it comes to gel formation, flocculation, aggregation etc.
Few solvents can, with stirring, to a certain percentage (as a drying aid, coalescent etc.) are incorporated classical representatives are here isopropanol, ethanol, methanol, propanol, butyl glycol other glycols, glycol ethers. The compatibility of these solvent additions and the tolerated amount, you elicit the best in laboratory studies, from experiences are additional amounts of 5-40%, depending on the underlying dispersion/emulsion and used solvents, possible.
