Spray painting inks can be divided into water – based inks and non – water – based inks according to the solvent. Water – based inks can be classified into pigment – based inks, dye – based inks and thermal sublimation inks by colorants. Non – water – based inks can be divided into oil – based pigment inks and solvent – based pigment inks. From a chemical perspective, oil is also one of the solvents. We collectively refer to them as non – water – based inks. In addition, there is another type of ink, ultraviolet (UV) curable ink, which is rarely mentioned in China nowadays. Inkjet inks can be roughly divided into these 6 types.
Advantages and disadvantages of various spray painting inks:
(1) Water – based dye inks: Their advantage is that the colors are bright. Since they are made with water, the water evaporates without causing any harm to the environment, making them relatively environmentally friendly. However, they have the disadvantage of fading easily and are generally only used indoors.
(2) Pigment inks: Their advantage is good light resistance; the disadvantage is that the colors are relatively dull.
