Members AA3JW Posted May 23, 2019 Members Report Posted May 23, 2019 If I do not have actual Barge thinner, can I use acetone, or mineral spirits to thin it? Quote
mikesc Posted May 23, 2019 Report Posted May 23, 2019 (edited) https://leatherworker.net/forum/topic/85867-contact-adhesives/ The MSDS for the Barge "universal" thinner says it is Methyl ethyl ketone.. So.."Mineral spirits" which is denatured alcohol..probably isn't going to work.. Acetone should should work, test some first..( the Barge website lists many products, you don't say which you have ) take all the usual precautions re flame , flash points, handling , eye protection etc..the vapours of acetone are bad for you..you do this at your own risk etc etc.. Btw..Methyl Ethyl Ketone is also know as Butanone https://en.wikipedia.org/wiki/Butanone Read the wikipedia page..you may have some around but under another name ..look at what you have..then look up the MSDS..look for ( use the "find" control usually under "edit" in your pdf reader and type Methyl Ethyl Ketone..hit enter, if any solvent that you have is actually Butanone or Methyl Ethyl Ketone, it will find where it mentions it in the MSDS for what you have..

Members TonyRV2 Posted May 23, 2019 Members Report Posted May 23, 2019 The correct solvent for regular Barge contact cement is Methyl Ethyl Ketone (MEK). You can purchase this in quart cans and larger at various hardware stores. A google search will turn them up for you. Note that this is the correct solvent only for Barge, no others, as they all use different stuff.

mikesc Posted May 23, 2019 Report Posted May 23, 2019 (edited) That MEK substitute ( Kleanstrip ) is ( according to it's MSDS ) Ethyl acetate..yes it would work for washing down and prepping polyester, melting or "welding" some plastics etc.. But, as a thinner for anything that is normally thinned with Butanone, not so good, it might well have a tendency to go somewhat "stringy"..depends what is in the "adhesive / glue / cement"..Acetone is better if you have no Butanone / MEK ..But Acetone will evaporate faster than Butanone.. I'm always amazed at what you can just walk in and buy in large ( ish ) quantities in the USA without having to sign a "poisons register" or otherwise leave a trace of who buys large amounts of things that can be mixed to go bang spectacularly..or as accelerants, or as solvents for things that can get you into trouble..France is similar.. :) Btw..Think of your local fire service..if you are keeping things that can go bang, or are dangerous around, let them know where you store the stuff*....that way..if you have a fire, they are forewarned, it can keep them from being injured or worse.. * I count ammunition as something to let them ( the fire service ) know about in case of a fire too..But not everyone does..

bikermutt07 Posted May 24, 2019 Report Posted May 24, 2019 Just for clarification, @mikesc Mineral Turpentine, or White Spirit, like denatured alcohol is also a solvent. However it is a different chemical mix of hydrocarbons and is distilled from petroleum, giving it slightly different chemical properties, and a less sustainable starting point. The primary use of MineralTurpentine is as a Paint Thinner.Aug 23, 2015 Denatured Alcohol Uses (or Methylated Spirits) | Ecostalk Quote I'm not paying 80 bucks for a belt!!! It's a strip of leather.

I just get the thinner when I order the glue (Renia). Just not worth the trip down town to save $10 (after the trip, I wouldn't be saving that anyway).

mikesc Posted May 24, 2019 Report Posted May 24, 2019 MEKP nope..not the same thing as MEK..the "peroxide" suffix makes all the difference..lot more Oxygen just looking for something to react with, or just to go "boom..the "peroxide part is a suffix in the name..but is actually two Oxygen atoms in the middle of the molecules of "peroxides".. https://en.wikipedia.org/wiki/Peroxide The one ( peroxide ) that almost everyone knows of..and probably has some in the kitchen / bathroom / garage.. https://en.wikipedia.org/wiki/Hydrogen_peroxide Hydrogen peroxide produced many "bottle blondes"..as they used to be known when I was a lad..and saw a resurgence with the punks. MEKP https://en.wikipedia.org/wiki/Methyl_ethyl_ketone_peroxide The MEKP that we use in resin work ( as a catalyst ) is "diluted" to make it less likely to react / go boom... Nastily irritant, dangerous stuff, nevertheless..but at least you don't have to worry about jogging the bottle..

Sorry, I didn't mean to get you going on a whole thing. I didn't know mineral spirits were considered differently between countries. Here in the states I know they are different products. Spirits being petroleum based. I once tried to use it as reducer, it didn't work out very well. I certainly wasn't trying insult your education or level of knowledge.

Work ( practical ) based education , IMO beats theoretical 99% of the time.. Take Granite, someone with a degree in geology could tell us both all about aspects of Granite that we wouldn't necessarily know..But, I know from my practical experience how to sculpt blocks of it, and what tools to use on which Granites, which are suitable for what sculptures or engraving or carving etc..You I know deal with it in slabs, you know from your practical work with it more than I or a geologist about how to cut it, polish it, how to finish it, which types are better for what wear applications..when not to use various types ..I know a guy who is one of the largest suppliers worldwide of Granites, owns major quarries in India, sells slabs and precut counters and "kits" for funeral home and architects, ship large numbers of container loads every month..Doesn't normally "do" sculpture Granite, I wouldn't be "lost" if the two of you were talking, but a large amount of any conversation between the two of you would be way out of my field..I'd be extremely interested though, which is why I read all the threads here, even about stuff that I don't do, probably will never do..it is all interesting.. ps ..in our house, the alcohol comes out at the end of the work or end of the day, or for celebrations..it is nearly 20.00 hrs here..end of the working day for me today, so..I'll raise a glass of Guinness to you :)..Sláinte :) Quote "Don't you know that women are the only works of Art" ..

bikermutt07 Posted May 24, 2019 Report Posted May 24, 2019 @mikesc, Skol, Brother. I don't know much about the structural integrity of the different granites. We have a manager at our slab store location though, and you would think he has a degree. I'm pretty sure he bores people into writing the check. Lol. Our company is a family owned flooring company with a granite division. We deal mostly with resellers that make contracts with suppliers. Although, the name and number of a direct link could be handy. Quote I'm not paying 80 bucks for a belt!!! It's a strip of leather. How hard could it be? 4 years and 3 grand later....
