This new product for developing latent prints on the adhesive side of tape has the advantages of being more economical and far clearer than the other available processes, such as Crystal Violet. Sticky-side powder is simply made into a paste using equal amounts of water and Photo-Flo. It is applied to the adhesive side of tape with a camelhair brush and allowed to set for 10-15 seconds. It may be left on longer or rinsed off sooner. It may be reapplied, if desired. For more information on the mixing and application of this product, view our Technical Note.

This product is also available in a kit. Shelf life of powder: indefinite. Keep in a cool, dry place.
