AP3155 is an adhesion promoter for use with UV and LED curable inks when printing on Glass, Metal, Aluminum, Acrylics, HDPE, Coroplast, Polystyrene and other hard to print substrates. AP3155 is suitable for both interior and exterior applications. Testing is required to validate substrate, ink and adhesion. 
Wear protective gear including Latex or Nitrile gloves and safety glasses
Use in a well ventilated area
Apply AP3155 to the substrate with a clean, white, lint free wipe or microfiber cloth saturated with the promoter, covering the full surface and ensuring no voids
Using a clean, dry, white lint free wipe or microfiber cloth, wipe off AP3155, leaving a thin layer of promoter on the substrate (the substrate will feel slippery)
Load the AP3155 prepared substrate into the printer and print image using UV or LED curable ink
AP3155 will cure with the ink when flashed by the UV or LED lamp
Storage - AP3155 should be stored away from UV rays in conditioned space heated and cooled 72f
