Blacklight / Ultraviolet (UV) Viewable - MEK Based

Our Invisible Ink uses special High-Brightness Ultraviolet (UV) Blacklight Viewable compounds.  The Invisible ink glows a bright yellow under UV or Blacklight including our special UV flashlight.  Under normal light, this ink is completely invisible.  This ink can only be seen when illuminated by a UV or Blacklight emitting in the 350nm - 375nm light range.  The ink is permanent and can be applied to paper, plastic, wood and almost any substance. 

These inks are available in our writing pen and as bottles of ink.

Notes:

Please test on an inconspicuous area first!  MEK and DMF may cloud or discolor some plastics or paints.  Always keep cap on pen when not in use.  Always keep away from open flame.  This ink contains solvents which ae flammable.

The typical 380nm to 405nm UV LED lights don't work with the yellow ink   The 375nm and lower LED and fluorescent tube lights work excellently with the invisible yellow series inks.  If you have an inexpensive UV LED light, you most likely have a 395nm / 400nm type which will not work well with the invisible yellow ink.  If you have a UV fluorescent tube, the yellow ink should work well.

All UV fluorescent dye based inks will eventually degrade under sunlight after a week or two if left in direct sunlight.  If ink is not exposed to the sun, the ink will last indefinitely unless worn or washed off
