Someone also mentioned that resin is made from polystyrene? wouldn't think too much would be good for that. I wonder if the big manufacturers have played with it yet like Ionics perhaps?

Just a thought, isopropanol is much less dense than water' so i would have thought it highly likely that the small amount being used will sit at the top of your tank most of the time as it's not being circulated, the take off point will be at the bottom of your tank well away from the alcohol?

It sits on top of the water like a film.

But your drawing from the bottom of the tank???

Im sure they have, they will be on here regularly ( Hi Ionic Systems!! ).

Most typical ion exchange resins are based on crosslinked polystyrene. The required active groups can be introduced after polymeration, or substituted monomers can be used. For example, the crosslinking is often achieved by adding 0.5-25% of divinyl benzene to styrene at the polymerisation process.

It is nothing like the polystyrene we know,

Hi

You can buy it from any print suppliers try
litho supplies
Apex digital
abdick
or keene graphics.

Don't have thier numbers t hand but you can just google them.

Ive said it before but don't use too much as it will make any plastic very brittle over time, and wear a mask and goggles when you handle it is not nice stuff

oh yes 22 years , but at last i'm free . started this lark about xmas time not as well paid as printing but far better way of life, hopfully it will get even better during the summer months

if you add the iso to a near empty ibc and then start the ro it disperses evenly as tank fills
i have found that dilution rates as low as 0.05% is enough affect surface tension
approx £40 for 25 litres from most print suppliers
will not react with aluminium because the reaction is precipitated by mercury and it is in solution not neat
will not affect paint or plastic at these dilutions

I wonder what sort of effect it will have on 'self cleaning glass' over time as propanol is used to clean the glass before application and if application is bad it is re-cleaned with it!

So........................in time does it cause non-sheeting windows to sheet??

My first experience was a poor choice of customer. Isopropanol in tank and ready to go.

First job was a new shop front chocka with Georgian panes. WFP for these then. Now I knew with IPA there would be bubbles at the brush head but (insert non offensive word if necessary) ME I was leaving bubble bath down the pavement.

I was dreading the rest of the day if I could ever leave this first job.

Graciously (or not) the cleaners had been cleaning the outsides (bless 'em  )

I have found greasy prints clean easier with IPA in the water. Am yet to find out if "fatherless children" windows will come round to my way of thinking. I live in hope.

Now if this concoction can clean a barbecued window in one pass i will be indeed happy. Haven't come across one yet this year. I guess only time will tell...

How much did you put in?

Matt just wondered how you are getting on after moving to wfp ? Am trad myself and thinking of going over to the other side

Ok matey, lemme tell ya, its been the best move I ever made, absolutely no doubt about it.

Some guys on here said in time, shortly after going over, you'll have bad days and wish you'd never done it, you'll want to throw it out and go back to the ladder, they were right, those moments came, and lasted all of 10 minutes.

I love it now, I have a real enthusiasm for it, love my job all the more, I find it so much more challenging/rewarding and the money, well, its better than I hoped for sure, oh yess !!

So, Id would say without a doubt, do it. You WILL NOT regret it.

Did you mannage to keep most of your trad customers ?  ( sorry to hijack this post I will go now )

There are two people on eabay selling this stuff - one says it is 99.9% pure, and the other one says his is 97.7% pure.

Can this be true? Or are they both near enough to 100% not to matter?
