NANPAO liquid gel crystal silk screen spot coating printing UV varnish ink for paper

Technical and economic factors have led to a new varnish technology, the Radiation Curing. UV-curing varnishes are converted 100% into varnish films. No solvent escapes into the atmosphere.  For the curing, only a fraction of the energy is needed, compared with what is required in conventional thermal drying. Therefore, the radiation curing system has the following characteristics: no pollution, high processing speed, slight energy consumption.

This item is designed for non-gluable, non-hot-stampable applications. It is a low viscosity type. When compared with the similar products in the market, it is less irritating to skin; and, after coating, it shows high gloss, good slippery surface, no yellowing, excellent scratch resistance and adhesion, no odor, and will not stick to each other while stacking. It also meets the requirements of toy safety, paper recycling, and heavy metals of content.
