Q1: How does UV coating cure, and what are the key benefits of this process?
A: UV coating cures through photopolymerization when exposed to ultraviolet light, transforming liquid into a solid film instantly. Key benefits include immediate readiness for further processing, zero VOC emissions, high durability, and superior scratch/chemical resistance compared to air-dried or thermally cured coatings.

Q2: What types of finishes can be achieved with UV coating?
A: UV coating can deliver high-gloss, satin (semi-gloss), or matte finishes, all with excellent clarity and smoothness. Special effects like textured, soft-touch, or raised (3D) coatings are also achievable through formulation and application adjustments.

Q3: Are there substrate or application limitations for UV coating?
A: UV coating adheres well to coated papers, many plastics, and board stocks, but may require pretreatment on non-porous or low-energy surfaces (e.g., certain films, untreated plastics). Application is typically via roller, spray, or screen, and requires proper UV lamp output and curing conditions for optimal results.
