Q1: What is the main challenge of coating metallic/foil papers, and how does this varnish address it?
A: The primary challenge is achieving strong adhesion on non-porous, low-surface-energy substrates while preserving metallic brilliance and preventing coating defects like crawling or orange peel. This varnish uses specially modified resins and wetting agents to ensure excellent bonding and uniform film formation without dulling the metallic effect.

Q2: Can this varnish be applied in gloss and matte finishes, and does it alter the substrate's appearance?
A: Yes, it is available in gloss, satin, and matte variants. When properly applied, it forms a clear, protective layer that enhances durability without masking the underlying metallic sheen or foil texture. The finish remains true to the substrate's original aesthetic while adding functional protection.

Q3: Are there specific application or drying guidelines for optimal results on metallic stocks?
A: Due to the non-absorbent nature of metallic papers, controlled coating weight and thorough drying are critical. We recommend using IR or hot-air dryers to ensure complete curing before stacking or further processing. A test run is advised to optimize settings for specific stock and press conditions, preventing blocking or adhesion issues.
