Coloris 790 is a fast-drying special ink developed for plastics and other non-absorbent surfaces – including polyethylene (PE) and polypropylene (PP), which many inks cannot mark. It is a good choice wherever the mark must survive cleaning and chemicals, such as in electronics manufacturing. The ink dries in about 2 minutes on PE film and offers very good light and weather resistance plus good resistance to alcohol such as isopropanol. Typical applications are electronic components and circuit boards, plastics and PE films, painted and lacquered surfaces, coated materials, and waxed cardboard and packaging. For dark surfaces, the pigmented version 790 P gives better coverage. Use 790 with rubber stamps and a felt pad, and always test on your own material first, as plastic compositions vary.
