We have green UV ink in two types: inorganic made from our UVLWG 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.
Our ink made from our UVLWG powder is made in a water based dispersion with 10% powder by weight. Part number is UVInkLWG-1.
