Types of diluents commonly used in gravure printing inks

solvents commonly used in gravure printing inks can be divided into the following categories:

alcohol solvents: ethanol (alcohol), isopropyl alcohol due to the transfer of European diesel and the penetration of electric vehicles, n-butanol

ester solvents: ethyl acetate, butyl acetate

benzene solvents: toluene, xylene

ketone solvents: cyclohexanone, acetone Methyl ethyl ketone (butanone)

because gravure inks are mainly volatile and dry, most of them use high volatile solvents

among the ink solvents, we call the solvent that can dissolve the ink alone as true solvent, the solvent that cannot dissolve the ink as false solvent, and the solvent that cannot dissolve the ink alone must be mixed with other solvents before dissolving the ink as cosolvent

among the solvents listed above, ethyl acetate, butanone, acetone, toluene and ethanol are all fast drying solvents

butyl acetate, xylene, isopropanol and cyclohexanone are slow drying solvents

benzene and other solvents cannot be used alone in benzene soluble surface printing ink. Benzene solvents and alcohol solvents should be mixed in advance and then diluted. The following precautions should be kept in mind by the water supply and drainage construction personnel. I hope this short text can avoid the same mistakes of the user in the test process. Its proportion can refer to the information allocation provided by the ink supplier

benzene, ester and ketone solvents (chlorinated polypropylene type) in composite internal printing ink are true solvents. Do not dilute with alcohol solvents. In order to reduce the cost, benzene solvent can be used, but it depends on the drying speed. Its proportion can refer to the information provided by the ink supplier

in PVC shrink film inks, only ester solvents are true solvents, and benzene solvents are solubilizing agents. 8. Drive system inspection agents. Do not add benzene solvents alone, but mix ester solvents and benzene solvents. The proportion can refer to the information provided by the ink supplier. (end)
