    I am trying to make alcohol based ink eg.copic ink or sharpie pen ink, go further,by watering it down with alcohol so that the ink will not clump but the combination will create a plastic dye which will stick to plastic.
    I have experimented with Isopropyl 70% but this had mixed results and ofter watered down the ink so that it took colour out,i need an alcohol i can mix with the ink which will "keep" the colour and allow for it to spray.

    Any ideas?

    I had considered maybe 50% Isopropyl ? What do you think?

    Many thanks

    what do mean by stabilized? butyl solvates the ink, does not evaorate rapidly.
    other solvents are esters butyl or amyl acetate also have a pleasant odor, banana

    Hi again

    I need it to evaporate quite quickly

    the alcohol im considering are/ or / a combination of these..

    ethanol- bio ethanol fuel for fire
    isopropanol- isopropyl
    n-propanol/butyl-isobutanol/isobutyl alcohol

    ionol CP/
    Butylated hydroxytoluene


    What do you think?

    Also, when you say butyl do you mean isobutyl alcohol ? or Butylated hydroxoluene? or something else?
    im quite new to this

    butyl alcohol, the higher the MW the higher will be the BP and slower evaporation.Acetone is also a good bet--but-- since you will be diluting tthe ink viscosity will be affecred, it will not cover as well- its formulated to do a specific job -coverage will be terrible and prone to run.
