Ecotex® WR-BLUE is the Ultimate Water Resistant Diazo Emulsion. This textile emulsion is highly resistant to plastisol & water-based inks. An ultra-durable solution designed for long print runs extremely water-resistant. Before use, Diazo must be added and allowed to activate emulsion. It’s easy, just see Diazo for simple Instructions. Once the Diazo has been mixed it is ready for use. Apply to clean, degreased, dried screen with a scoop coater. Be sure to use appropriate application techniques. Reclaiming Ecotex® WR-BLUE is easy with Ecotex® Emulsion Remover. Requires more water to develop the image. 

NOTE: This emulsion comes with a bottle of Diazo.

Helpful Hints to Ensure Your Emulsion Lasts Longer Once Mixed:

  • Always use distilled water to mix the Diazo sensitizer.
  • Keep in a cool area, emulsion will break down much faster in heat. Keeping emulsion in a fridge can help to give a slightly extended shelf life, however, emulsion that has gotten to the point of freezing will no longer work properly and must be replaced.
  • Keep the emulsion lid on tight to preserve air and light leaks.
  • Gently mix the emulsion each time before use to help extend the life.
  • For long runs of over 1,000 shirts – use Ecotex Emulsion Hardener to extend the life of your stencil.
  • To ensure best results, date your emulsion once mixed and keep an extra container on hand once the emulsion is about to expire*

Shelf Life:
10-12 months
Activated: 1 Week

ill be real

I haven't used it yet the shipping got delayed which I know isn't in your control but I was waiting on this for up qwords of 10 days.

don�t buy if you cant use up VERY soon

i bought this thinking the description fit exactly what i was looking for, but after purchasing i was looking for more detailed instructions on mixing the diazo on screen printing direct's website and only there do they say the shelf life is one week after activation. so i returned it because i am one small person who could not possibly find enough screens in the world to coat in one week and use up the whole pint. the only reason i give it 3 stars is because i couldn't actually use it for my personal needs, i have no idea well the product works. though i shipped out my return on december 29th and it still says it hasn't reached its return destination, which should be domestic so i don't know how it's not even there yet. hoping the customer service is good and they get back soon cause it's been a pretty disappointing experience so far.

Need pressure washer and emulsion remover to remove this emulsion

Works amazing! Definitely takes longer to burn screen than speedball. Around 14 minutes on my Yudu machine works great. Many people complain that the emulsion will not come off with emulsion remover which it will not using just the remover alone. My last resort was using my car pressure washer after soaking in emulsion remover. Works beautifully and did not damage screens at all. This may be the only way to remove this type emulsion.
