Title: Screen wash and reclaim chemicals
Post by: Maxie on August 01, 2015, 08:20:37 AM
I read the safety data sheets on the chemicals I use for removing ink from the screen and in the dip tank and they sound horrific, hazardous and envirmentally bad.
I assume these are for the concentrated chemical, does anyone know what happens when you dilute them?
Does anyone know what can be safely put into the drain?
I have read about home made filters, etc.   Are these enough?

CCI has an Enviro Line that is Soy and Citrus Based:

Kiwo also has a stronger concentrated system that is diluted with water that works great:

these are safe for the drain but its always recommended to have a drain catcher

We use CCI Enviro chemicals for our dip tank and my guys say it's great and doesn't stink. Yesterday I bought a bunch of their chemicals for other uses, they are all natural and apparently not hazardous. It's worth a try.

We got CCI Gem-Zyme in our dip tank, CCI Citra Paste for cleaning screens and CCI Envirohaze for haze removing.

used to be exact same thing for us...UNTIL I made a ink cleaning dip tank. Go from press -> dip tank with CCI IW108 -> rinse ink off with water -> dip tank with gem-zyme -> powerwash -> compressed air, wrack it up....no scrubbing, no mess, no hassle, faster than anything, reclaim is easy as pie now.

I just dip in supra and blast off the ink and emulsion in one step. I do degrease/dehaze with 701 after though. I found I had snake eye issues when I tried to skip that step

same here but with CCI Dip and Strip on the strong side.

screen comes out of the dip mostly dissolved and with a quick hit of the pressure washer and the 701 scrub takes about 2 min cycle per screen.

Curious what did you use for the home made dip tank?

same here.  until we went to Easiway Screen Perfect and then Saati DirectPrep2 in our shop, we had problems.... now we degrease/prep EVERY screen and our troubles have gone away.

*this is likely due to the fact that we have really hard water here, but regardless, it's a requirement for us to get good screens.
