 STICKY-SIDE POWDER FORMULA:
1. Place 1 teaspoon of powder 
in a shallow jar or mixing bowl.

2. Equal parts of Photo-Flow 
and water are mixed with the 
powder to form a THIN paste.
PROCEDURE OF APPLICATION 

1. Brush this mixture with a 
camel hair brush onto the 
tape's adhesive surface.

2. Wait 30 to 60 seconds.

3. Rinse under a gentle stream 
of cold tap water.

4. Allow tape to air dry.

5. Photograph any developed 
ridge detail.

Reagent Applicabilities:

Non-Porous surfaces
Post-Cyanoacrylate
Tape surfaces


Other Chemical Name(s):

None


Working Solution Shelf-life:

Prepared as needed.
Process Summary:
The reagent is prepared as a paste, then is brushed unto the adhesive sides of tape surfaces. This reagent is considered to be a more economical alternative to other adhesive-tape processing methods. Cyanoacrylate fuming does not inhibit the use of this reagent.
Accepted Deviations:
Commercial kits are available for use. The reagent may be mixed vigorously to create a foam solution. The reagent may be repeatedly applied, if necessary, to improve the detail.
