EVAPORATION RATES OF SOLVENTS

Edition: April 2008 Replaces 05/06

To be made ready for printing, printing inks are adjusted by adding thinners. The drying speed of the inks can be retarded by using retarders and accelerated by adding accelerators. Thinners, accelerators and retarders recommended for our inks, represent solvents or mixtures of solvents that correspond with the series of inks concerned. These solvents are used for adjusting or correcting the drying. Among others, they differ from each other by their variable evaporation rates. The evaporation rate is indicated in relative numerical values (figures). These rates are established by supposing the evaporation rate of one solvent to be 1 and by indicating those of other, slower drying solvents as multiples of this rate. Ether is generally supposed to be 1. Evaporation rates of commonly used solvents:

Packing code: It concerns a standard cask. If you wish another packing size, we will be pleased to send you the appropriate packing code.

Example: The evaporation rate 8.3 of ethyl alcohol indicates that this solvent evaporates approx. 8 times slower than ether, but approx. 4 times faster than ethoxypropanol.

Because of the differences in materials for printing, processing conditions and test criteria this Technical Data Sheet can only be of advisory character. Our data reflect the latest state of our knowledge and are based on the characteristics established in the laboratory and on practical experience. Your own tests with the original materials under the respective conditions are indispensable. We disclaim any liability for applications for which this ink series is not foreseen.
