UV Invisible Ink - Red
We have red UV ink in two types: inorganic made from our UVLWR powder and organic made from our UVXPBR powder. The inorganic materials are sunlight stable, heat stable and last a very long time. However, they are more expensive, not as bright and harder to print with because the inorganic materials are very fine crystals. The organic materials are brighter, cheaper and can bed dissolved in some solvents, but fade in about 1 week under sunlight. If left in the dark, the organics can last years.
UVSWR Series - Red Inorganic Dispersions
Our UVInkLWR-1 is a custom formulation made from our UVLWR inorganic powder in a water based 10% dispersion.
(UVXPR Series) - Bright Organic Red Solution
Blacklight / Ultraviolet (UV) Viewable - Acetone Based
Our Invisible Ink uses special High-Brightness Ultraviolet (UV) Blacklight Viewable compounds. The Invisible ink glows a bright red (617nm) under a 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 - 385nm light range. The ink is permanent and can be applied to paper, plastic, wood and almost any substance. Not recommend for use on skin since the ink contains acetone. The ink does not wash off.
Available as an ink in 1/4 Ounce or 2 Ounce bottles and in writing or jumbo marking pens.
