Water Based Polymer The connecting material determines the drying type, drying speed, gloss, wear resistance and firmness of the ink. In water-based inks, water-soluble resins and emulsion polymers mainly act as connecting materials. Viscosity is the most important control index in the application of water-based ink binder. In the printing process, the low viscosity of water-based ink will cause some disadvantages, such as light color, dot expansion, uneven ink transmission and so on; On the contrary, if the viscosity of water-based ink is too high, the transfer performance of ink is relatively poor, which is prone to dirty version, paste version and other disadvantages. In addition, the connecting material should also have good solubility, good dispersion of pigment, excellent color development and good adhesion to the substrate. In short, the binder determines the rheology, viscosity and printing adaptability of the ink. Therefore, it is very important for the production of connecting material.
