Why did you send him all those kisses?

Because I love Purolite and all its workers  No I was just covering my company name, Luke

Just been speaking to Purolite about their MB400 Resin and putting Pure Isopropanol through it. The specialist I needed to speak to was not in so I sent him this email:

Hi Brian,
 
I spoke to one of your collegues earlier today regarding the use of Isopropanol Pure Alcohol for Pure Water Window Cleaning.
 
As you may be aware alot of Window Cleaners use pure water to clean and some use a little Isopropanol added to the water to help with the cleaning process but the majority of Window Cleaners have their water already filtered before it goes into their storage tanks in their work vehicles and then add a little Isopropanol into their water tanks.
 
My problem is I filter onboard with 2 DI vessels holding Purolite MB400 Mixed Bed Resin as my TDS/PPM is only 24 here near ********. So I am worried that if I put Pure Isopropanol into my tank it will be removed by the Resin before reaching the windows.
 
To you this question may seem stupid but to me I just dont know. Will the Resin remove or absorb the pure alcohol or because its pure does it have nothing to remove?
 
I know that this alcohol is pure when read with a PARTS PER MILLION TDS reader but I was concerned that the Resin may be removing PARTS PER BILLION, therefore resulting in the alcohol being removed too. Do you follow?
 
Thanks, for your help, Luke , ********* Professional Window Cleaning

Luke ISO is fluid as is water if what your saying was true the water that is put through resin would all be absorbed by the resin resulting in air coming out the end of your pole,resin is positivley and negativley charged this process absorbs impurities in the water leaving it pure.The amount that i`m on about using would not effect the resin at all,it`s been checked by a resin supplier and they`ve given it the ok to be used if wanted.

ah I c.
I been looking on fleabay and it looks like it;'ll cost about £3 a day with a 500l tank.
Anyone find out who's the cheapest yet?

NWH:

Ill post his reply, Luke

[NWH]

£3 a day i don`t think so,i`ve had my 5ltr bottle for well over 3 months and like i said it dosen`t need putting in everyday as it stays in the tank mixed in the water,add water to it ie top it up and you should get 2000-2500ltrs out of 3/4 of a pint.Remember if you have bubbles at the brushead you still have some in your water.

[Ian Curtis]

But how many bubbles? How many bubbles is too much?

[NWH]

As the water hits the glass it looks for a split second like it has detergent in it,almost straight away it dissapears.All the time your brushing it will bubble up,and then when you rinse the bubbles will go again and then the window will dry as normal,you only get bubbles when brushing and rinsing theres no bubbles during the drying process.

[Ian Curtis]

So it looks like buy 5l, fill a 500l tank with pure water and add a pint of ipa and as long as you don't use the whole lot n one go, you shouldn't have to add any more ipa until it stops bubbling? But if the first dosing uses a pint, doesn't it get massviely dil;uted on subsequent days?

[NWH]

Yes it does get diluted but when you stop getting bubbles add the same measure to another 500ltrs or what ever tank you have.You should get at least 2000ltrs to 1 measure.

[Captain Scarlet]

Does anybody on here use both hot water and Isopropanol? I would think there is some sort of risk with a heater and a flammable liquid? Luke

[Captain Scarlet]

Isopropyl alcohol vapor is heavier than air and is highly flammable with a very wide combustible range. It should be kept away from heat and open flame.

It is also toxic, so be careful about getting it on your skin and in your body!! Luke

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?

[Captain Scarlet]

Here is some evidence to suggest it might cause problems on bare metal/aluminium frames:

Like most alcohols, isopropyl alcohol reacts with active metals such as potassium to form alkoxides which can be called isopropoxides. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.

[Captain Scarlet]

Pure Isopropanol is "anhydrous", which means it contains 0% water, Luke

It sits on top of the water like a film.

[Ian Curtis]

So why doesnt it sit on top of the water in the tank?

[Captain Scarlet]

So do you mix it in before work? And have you had any problems with it reacting with bare aluminium? Luke

Because it is less dense, Luke
