Pregasol dried on screen during reclaiming.

Postby Splitear » Tue Jan 29, 2013 8:00 am


I'm using a diluted Pregasol K-FL to decoat my screen, due to an emergency I sprayed it on my screen to decoat (usually i leave it for 2 minutes then rinse with water to successfully reclaim my screens), i left the pregasol on the stencil for an hour, came back and it had dried, now it will not wash off at all, no matter how much pressure and chemicals i use.

Looking at the Kiwo datasheet, it says avoid allowing it dry as it is incredibly hard to remove dried pregasol on a stencil.

I was thinking of buying Pregan Paste to try and remove this stencil, but i was wondering if this would work? Or if anyone else has encountered this problem?



I also thought of buying Pregasol P (a ready to use decoater) as it is stronger an much better at removing emulsion, i was wondering if my case was hopeless or not, thanks.

Not with that particular product but yes, when that happens with my stencil remover it's time for new mesh. Haven't made that mistake in a long time, my guess is you won't from now on either!
