UV Nitrogen Hard Coat Textures for Membrane Switch Applications

Top-Quality Membrane Switch Coatings

In the 1990s the demand for durable, scratch- and chemical-resistant UV coatings reached its peak. The best method for producing these coatings required curing specialty inks in an inert, oxygen-free atmosphere, and so the UV nitrogen dryer, which floods the environment with nitrogen, became the equipment of choice. Many UV nitrogen dryers also incorporated plasma bulbs at the head of the dryer that cured the very top layer of ink to create a skin that could be controllably wrinkled to varying degrees, offering a wide variety of surface textures from a single ink.
