Advantages of Wood UV Drying Machines: Surface drying + solid curing within seconds to tens of seconds; immediate stacking/flipping/post-processing upon exiting the line, significantly reducing work-in-process and turnaround time. Disadvantages of Wood UV Drying Machines: Requires UV-curable coatings: Ordinary solvent-based/water-based paints without a photoinitiating system and polymerizable components cannot form a film using UV light.

The curing time for most UV paint drying machines is typically between 1 and 10 seconds. However, this is a range, not a fixed value. Actual drying time will vary depending on conditions. Different equipment and processes can lead to significant differences in curing speed.

When using coatings designed specifically for UV curing and properly designed with a suitable light source, dosage, and process, a Wood UV Drying Machine can significantly shorten paint curing times, achieving millisecond to second curing speeds, thereby improving line cycle times and productivity.

Wood UV coating is a UV-curing coating containing a photoinitiator. After application to the wood surface, UV radiation (for example, using a wood UV drying machine) triggers rapid polymerization and instant film formation.

It can be completely transparent, or it can appear opaque or hazy. Achieving high transparency requires: (1) Selecting a transparent and low-yellowing UV formula that matches the light source (the wavelength of the wood UV drying machine); (2) Controlling the substrate, polishing, and sealing.

A wood UV drying machine can be safe, but it's not inherently safe. Safety depends on equipment design (enclosure, interlocks, and light filtering), light source type (LEDs are preferred over mercury lamps), ventilation and ozone treatment, strict operation and maintenance procedures, and personnel protection and training.
