Water Based Waterproof Varnish
First choice for green printing: Multifunctional advantages of Water based waterproof varnish
Water based waterproof varnish is an environmentally friendly coating material designed specifically for paper prints. After being coated on the surface of printed matter and cured, its waterproof performance is far superior to that of ordinary water-based varnish. When water droplets contact the coating surface, a lotus leaf-like waterproof effect (i.e., "lotus leaf effect") can be produced, effectively protecting the printed matter from moisture. With its excellent waterproof and environmental performance, this product is widely used in high-end packaging and various printing scenarios that require waterproof effects.
Excellent waterproof performance
After curing, the coating shows a lotus effect, and water droplets will not penetrate the surface, but will form beads and roll down.
Suitable for a variety of humidity or accidental contact with water scenes, ensuring that the printed product maintains its integrity for a long time.
