1,tin plated steel printing ink has heat resistance
The tin plated steel printing ink is a heat-curable ink. The printed metal tins needs to be heated and dried, and the baking temperature is generally 150-205°C. By heating, the steel tin plated printting ink binder transforms from small molecules to macromolecular network structure, forming a hard ink film to ensure that the color of the ink does not change after baking.
2, metal tins printing ink has solvent resistance.
The last process of tin plated steel printing is glazing. The varnish contains solvents such as benzene, esters, alcohols, ketones, etc. Therefore, the steel tin plated printing ink must have good solvent resistance, otherwise pattern bleeding and coloration will occur, which will affect the quality of the printed metal tins product. .
