This paper mainly introduces the newly developed UV-G BU 3 1 UV-curable glass ink with high hiding power.
It is suitable for printing glass products that require partial opacity and partial light transmission. Most of the traditional crafts use two-component heat-setting inks. Although they have good hiding power, they have low efficiency and high energy consumption. In addition, irritating gases volatilize during printing and baking, which affects the environment and workers' health. Due to the limitation of UV penetration, the ink layer is not too thick, the ink color is not very deep, and the hiding power is not very high. UV-G}-31 adopts a special photocuring system to make the ink in high covering power, ink In the case of thicker layers, it can still cure quickly and deeply. The cured film has good hardness, excellent abrasion resistance and water resistance, and good adhesion. The ink does not contain volatile organic solvents, no irritating gas, and does not block the screen during screen printing. The mesh number of the screen is generally 100-300 mesh, and there are dark green, emerald green, silver white, white, dark black, gray white and gray black and other colors to choose from.
