Pearl powder is often used in ink, paint, etc. When the pearl powder is used in printing ink, what are the factors influencing the pearl powder ink adhesion of?
In pearl powder ink three components (pearl pigment, solvent, resin), pearl pigment itself is no adhesion, have to rely on the resin to adhesion, so the resin in pearl powder ink adhesion plays a decision factors. Tens of thousands of different kinds of resin, with a variety of different substrate adhesion. And glass, for example, good adhesion, and it is not good, steel adhesion and good adhesion of PVC, paper adhesion is not good, so the selection of the resin, to a large extent affected the adhesion. In addition, the ratio of resin in the ink may also affect adhesion.
