Q1: What are the advantages of UV curing for paper coatings compared to conventional methods?
A: UV curing enables instant drying through photopolymerization, allowing for high-speed production, reduced energy use, and no VOC emissions. The cured film provides immediate durability with superior scratch, abrasion, and chemical resistance, while preserving paper integrity without moisture-induced warping.

Q2: What types of paper substrates are compatible with this coating?
A: It is compatible with a wide range of papers including coated, uncoated, cardstock, and specialty paperboards. For optimal adhesion and finish consistency, surface energy and porosity should be evaluated. Pre-testing is recommended for textured, recycled, or low-density papers to ensure performance.

Q3: Are there specific screen-printing or curing requirements for paper applications?
A: Use appropriate screen mesh (typically 120-200 T) to control coating thickness and prevent excessive absorption. Ensure adequate UV lamp intensity and exposure (usually 200-400 mJ/cm²) for complete curing, especially on porous papers. Proper substrate stabilization may be needed to prevent curling during curing.
