1-methoxy-2-propanol regulates, i. e. retards, the drying of printing inks, but two facts should be noted in this respect.
1-methoxy-2-propanol (evaporation rate= 22; ether = 1) dries more rapidly than ethoxyethanol (evaporation rate = 43).
In other words, somewhat greater amounts are required to retard drying.
A general rule is that drying regulators incur the risk of solvent retention and blocking if their proportion is too high or
if inadequate time is allowed for drying.
This also applies to 1-methoxy-2-propanol.
1-methoxy-2-propanol can also be used for cleaning printing plates and for thinning printing inks.
