PUA242 high-gloss topcoat paste (two-component)

When finishing a water-based print, the gloss should be consistent across the coated area, from large solid areas to fine details. PUA242 is applied over the printed surface to produce a glossy finish. During sample approval, tilting the print under a light makes variations in gloss easier to spot.
