EPA - Multi-Purpose Screen Printing Ink
1. Overview & Applications
EPA Ink is a premium 2-component, multi-functional screen printing ink. It offers excellent adhesion and chemical resistance on a wide variety of challenging substrates, including hard-coated (abrasion-resistant) PC and Acrylic, metals, glass, ceramics, melamine products, baked enamel surfaces, vacuum metallized surfaces, UV-coated surfaces, engineering plastics, and treated PP/PE.
Primary Applications: Widely used in electronics, hardware, appliances, eyewear, and packaging.
