A UV curtain coating machine is a type of equipment specifically used for industrial surface coating. The "curtain-type" term here refers to the liquid curtain formed by the coating, not curtains or fabric products. UV stands for ultraviolet curing technology. The coating cures instantly under UV light, forming a hard, wear-resistant coating.

A UV curtain coating machine is a specialized device that coats substrates by forming a "flowing curtain" of liquid coating, which is then conveyed through the curtain by a conveyor system. It relies on the gravity and fluid dynamics of the liquid coating to evenly deposit the coating onto the substrate surface.
