Sirchie - Latent Print Powder, Dual Purpose Black

Sirchie pioneered the use of fluorescent latent powders when it introduced these dual-purpose powders. Dual Purpose Black is oxide in nature, and is therefore recommended for use on all oxide surfaces including painted wood or metal and most plastics. This unique formulation also contains a fluorescent compound that provides fluorescence when exposed to ultraviolet (UV) light. This is especially helpful when working on multi-colored backgrounds.
