Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
I just want to add a little bit more info (sorry i dont get on here much lol)....its been about 1 a week for 7 weeks. 90% of the time it's happened when i've pulled it out of the cabinet to put emulsion on. and then i yell "ARE YOU SERIOUS" it's generally a 6-8" section that has separated from the side. within 2-3 days the whole side has come unglued. I've always bought my screens from poconoscreen. Some of these have been used probably 100 times over 5 years, at least 1 was only used once.mesh #'s are from 137's, to 158's to 230's.The only thing i have changed in the mix is changing to a pink degreaser by ICC chemicals that smells like cherries...just brush a light coating on there and hose it off...i dont ever put it on the 'frame' part.when i do it, i always work from the back side of the screen, i have no idea what "my other people" are doing because i cant baby sit but i guess i will have to eavesdrop in there next time and re-teach.i keep the drying cabinet on about 15-20 minutes tops and i think it maxes out at 100 degrees...(again, hasnt been an issue in the 5 years previous)super frustrating....P.S., i couldnt stop him from buying this boat. lol :-|
First, get that pink crap out of the shop. It's an abrader. They tried to push that stuff on me too and I told the guy I didn't want it on my screen and he had to demo it and did it anyway. Pissed me off.That stuff makes an AWESOME hand cleaner though...so I guess keep it for that.If the only thing that has changed is the person, they are doing something different...watch her work.Did somebody recharge the chems in the tank and put too much in?
BTW, for those unaware, and "abrader" is any of many screen chems or pastes with an abrasive medium added to "roughen up" the surface of the mesh in the degreasing process. It's a dinosaur from the old days where the theory was on new screens it would help the emulsion adhere better. It was supposed to be used just on the first degreasing/prep for new mesh.Problem is it doesn't help the emulsion stick any better than a plain old properly degreased screen, and it shortens the life of the mesh considerably. Might was well take some 220 grit sand paper and go to town on it.Shelly, bag up any of that pink stuff you have left and get it out of the shop. Consider it deadly poison for screens.

Consider it deadly poison for screens.Ulano says that abrading the screen is still recommended when capillary film is used, as it doesn't "sandwich" the mesh as direct emulsion does.Though Ulano was a little late on the change in industry thought that it was best to not use it on all screens, unfortunately, it does make a certain sense with film. Whether the increased adhesion outweighs the mesh damage and shortened mesh life is a great consideration.On the other hand, Autotype's instruction's merely say "Prepare the mesh thoroughly"Almost enough here for a new thread, though I think that we may have discussed abrader in the past, along with the Autotype micro photographs of damaged threads as well as the results of using cleansing powders and their remaining embedded particles.

With the gravely crap in it that smells like cherry candy? It's the worst. That is a degreaser AND a dehazer AND an abrader. In other words, it's screen death for statics. That means some of these screens are getting double doses of dehazer, AND the mesh is getting weakened by the abrader. No wonder the glue finally let go.
Just trying to make sure of what I have.I have some pink stuff that smells cherry but it's Saati HR-6 (I think that is the number).What is the scoop on that chemical?
