For volatile drying inks, it used solvent can be divided into the following three categories: 1, true solvent.
Of polymer resin has dissolved the ink solvent for the resin is solvent.
2, cosolvent.
Used by itself cannot be dissolved polymer resin, but to a certain limit an amount, mixed with true solvent used, can provide a certain degree of solubility.
3, thinner.
Used by the solvent insoluble polymer resin, also helpless lysis, but to a certain limit, amount can be mixed and true solvent used, it plays a dilution effect, lower than the true solvents, cosolvent, can reduce the cost.
The classification of the solvent is relative, for a solvent in the role of a certain type of ink is the true solvents, and in a different kind of printing ink can also be used as diluent.
