Flat Fox PHU 2 one step is a pure photopolymer One Step presensitized emulsion that is universally suitable for all inks, including solvent, water-base, and discharge inks.
 
If you haven't used a one step polymer before and are used to Diazo Emulsions, try this out, it's a great emulsion - not only does it have a really long shelf life, it exposes much faster and washes out easily.

This emulsion exposes up to 4 times faster than emulsions that are mixed with Diazo. This is great for when you want to get fine detail exposed on your screen and perfect for simpler designs too. Once exposed and cleaned out and dried, you can put your screen back onto your light for post exposure to make the stencil more water resistant. 

STORAGE When sealed in the original container and stored in cool conditions, Flat Fox PHU 2 will maintain its original properties for one year from the date of production.
