I am trying to get some of this stuff to dilute my epoxy resin with. I understand that it comes in many forms, including methylated spirits.
Can anyone out there who knows these things advise me if they would all be suitable for thinning epoxy resin (Z Poxy Finishing Resin to be precise), or if there is a preferred version, and a source? If I used meths would the diluted resin be purple?

Hi Chris, As usual the EU has had it's say on the subject:-
"The European Union agreed in February 2013 to the mutual procedures for the complete denaturing of alcohol:

Per hectolitre (100 L) of absolute ethanol: 3 litres of isopropyl alcohol, 3 litres of methyl ethyl ketone and 1 gram denatonium benzoate. "

The MEK should help the solvent properties 👍
Purple resin would look quite nice, different, ! 😉
But I don't see the colouring agent (methyl violet, AKA gentian violet) in this mix. Optional extra!
Cheers Doug 😎

you can thin apoxy using the boiling water method fill a bucket or sink with boiling water put your apoxy in a tin (old soup)lower it into the boiling water and the apoxy will become less viscose ,you have to work quick as it will thicken as it cools you can also use a Bain Marie boiling water in the lower pot resin in the top one and steam until the desires thickness(a bit like melting chocolate) by using this method you dont change the chemical structure as you would if you used acetone

Hi Chris
If you thin it will change the structure as others have advised.
Gentle heat will result in the mixture becoming easier to work and apply as marky advises.
If you apply too much heat there is a danger of fire so tread carefully. if you do use heat you will greatly speed up the curing process so mix small amounts and apply quickly. A dry brush is recommended to mop up any runs.
In the recent hot spell I was using some to repair a fitting and the mixture was really thin and set in less than 60 secs.
I use Acetone to clean my pots and brushes and the odd spill but wouldn't use to thin the resin
Good luck and please post how you fared
Dave

I think this has got a bit off the track. I was asking about denatured alcohol, not acetone. DNA is ethanol and can be used to thin epoxy. see this You Tube video :

denatured alcohol is industrial methalated spirits it is still extensivly used in the printing industry a chemical supplier should be able to oblige ,my mother in law used to work in a chemists shop in the 50s and you had to sign for its purchase because of the consumption by alcoholics

Thanks Dave, I must admit I did misinterpret your note about your use of acetone.
In the you tube link he thins his resin down to the consistency of water, and it then takes about 4 hours to go off, which is what I want.
Looking at the Bonneyman website it seems you have to have a government authorisation to obtain some types of denatured alcohol. Their site also points you to the gov.org website which explains it all in full. Apparently for low volume users it is less restricted, particularly if you are a school!

and I thought the Germans were over-regulated!! 🤔
By the way, as far as I understand the myriad variations DNA is not necessarily Meths.
Most versions of DNA are solutions without changes in the chemical structure, and should not affect the basic structure of the resin as it (basically the ethanol) evaporates and leaves the original resin.
Happy licensing (and laminating!) don't get drunk 👍
Cheers
Doug 😎
PS Some DNA has acetone as an additive which DOES change the chemical structure of the ethanol. (Please don't ask me what it becomes 🤔 CIDK!)

Hi Chris
Always happy to share my experiences.
Epoxy is basically a glue and whilst the aero boys like to use it with glass cloth to cover their wings because it bonds well to the wood and remains slightly flexible, my experience is it is dear, adds significantly to the weight, is difficult to apply evenly and has a nasty habit of running after application. We used on the large liners, having also seen the hype on U-Tube, and really struggled with the application.
If I was using this as a sealing coat with or without cloth then I prefer Polyester lay up resin which is cheaper, thin and easy to apply, has controllable setting time and produces a much harder finish.
Good luck with the registration, not sure I would want to get that close to HM Customs & Excise!
Happy building
Dave

Dave, one of the advantages of epoxy that should not be discounted is that it is almost completely odourless. THat is an especial advantage in places where the winter is long, cold and snowy, and painting and epoxy-ing has to be done indoors.

When I have got the DNA and epoxy/polyester resin sorted out and I want to coat the inside of the boat, do I just do the hull, or should I wait until the deck is on?

Hi Chris
Probably easier to apply to the hull with the deck off. You should leave the deck join area clear to allow for the glue. The bottom of the deck will also benefit and I usually use a pencil to mark where the formers join and keep the coating off this area. If you are using epoxy for the coating and the joining glue this may not be a problem. Once the deck is on apply another coat over the joints to seal.
If you could a build blog would be welcome and helpful to other members, please.

Thanks Dave,
I will do a build blog when the model is finished. It is a Jenny by Aero naut. It is supposedly a simple model to make, and so far it is proving to be so, except for a few parts of the construction which are not very well explained in the instructions. If there is the possibility of misinterpreting some instruction, guess which method I use? It's only when I get to the next stage that I find I have gone wrong! I do read the instructions first but some parts are, to me at least, unclear. I have been able to overcome the problems I have created, although the model will only be 99.99% as per the plan.
I have some photos of the build so far but not a complete reference.

I had a reply from HMRC stating that a change in the regs a few years ago allowed the production of meths without the purple dye. This is apparently CDA - Completely Denatured Alcohol. I contacted Bonneymans, the only UK supplier of this type of stuff that I can find, and they said that they had never heard of it, even after I had advised them of the HMRC advice.
I replied to HMRC, as they had asked where/who I had been advised to use DNA, and I also told them of the lack of a supplier of CDA.
Their reply was that they would not provide me with authority to buy DNA because I only needed a small amount, and CDA was adequate for my purpose. My interpretation of the rules was that small users, such as myself, did not need the authority anyway, but Bonneyman's seem to want this in writing.
So in the end it looks like I will have to use purple meths.
Oh dear.

Hi Chris
I have used Iso Propyl Alcohol as a solvent for many years and also to clean electrical boards and contacts. You need the industrial strength 99.9% as the rubbing alcohol only has 70% IPA.
It will thin most resins and evaporate leaving little residue, so will have little effect on what you are intending. It's freely available as HMCR are not concerned that it will be used in place of Alcohol, which carries duty.
We as individuals cannot easily buy denatured alcohol in the UK and meths contains other additives which are unwanted for your purpose.
Cheers

Meths is ethyl NOT methyl that's why you can buy it from supermarkets etc. without a whole load of safety warnings! Methyl alcohol is VERY VERY toxic and the safety equipment required ( by the book) includes face shields rubber aprons and respirators! The meths you can buy easily is not anything like as toxic and can be used with little risk ( just keep clear of naked flames and DO NOT DRINK IT)

Aye there's the rub Doug.Wilmot and Mansour kept the exact fuel formula secret I believe . However it should be easy to find it with modern science techniques. But after the initial rush of nostalgia purchases from the likes of us would there be a market for them.I did the all sheet Hunter and painted it grey and put roundels and letter transfers on it. Did fly but had a glide like a landing swan.A semi controlled crash would be a good description of it. Which one did you put on 2 Mtr span gliders.100/ Scorpion I know one thing Doug .You and I should never meet 'cause we would spend all out time nattering. I think😁👍 Regards John .P.S.

RN. Dear god dont start mixing your glow fuel and Glycerine, thats Nitroglycerine, highly unstable, even to bump it could send you to your maker!!!! PS, had some old 50% nitro glow fuel in the shed for about 2 years, it had turned purple, almost pure nitro. Very slowly and gently added Methanol until it turned pale yellow again. Very dodgy

Hi John,
there seems to be a market for the 'one way' cardboard Rapiers motors, so why not for a reloadable Jetex?
Yep, I remember my Hunter gliding like a brick as well 😡
For the glider I only had the 50s, but the US version with the domed exhaust. Seemed to concentrate the thrust.
You may be right about meeting 😉 a few Triple Xs or similar would probably also get demolished in the process!
Re Ether, probably from the Apotheke (Chemist) not the DIY shop. But I have no need for it, or do I?
Think we'll get told off for hijacking this thread!!🤔
Cheers Doug 😎

Yes Doug we will get slapped wrists.Good point about reloading and I' ve got a domed 50b but I left it dirty after the last run .Combined with a bit of damp and the hole has corroded away round half the circumference.I'll try that Free Flight supplies shop. Tried getting onto Jetex forum but had to send E mail asking how. No form evident on site . With apologies to the mods for the Hi -Jack . If you need to say more go on chit chat or something. Cheers John Have a few forXXX me 👍

Hi Doug, Going bang was all about my worry. More bang for your bucks???? would hate to loose you for the forum just to see you disappearing though the hole were your roof used to be!!!!

PS, wonder if any of the security services have clocked our mixture discussion's??? might be a stern knock on the door soon!!!

Hi Mark, Thanks for your concern 👍 but don't worry, as I said that was only tongue in cheek musing / fantasising, although ..... 😉
Black powder for depth charge throwers is my limit at the moment

RE PS: that was also my concern 🤔 considering all the monitoring for 'keywords' that goes on these days.
Cheers (still on the loose) Doug 😎

if you want a convincing bang and a cloud of smoke have a look at magician's flash powder. A glow plug will ignite it !

Hi Haverlock, I already got some👍😉 From a German Magic Shop.
I have it in the 'Flash Paper' form so I can wad it for gun barrels.
And I still have the glow plugs from my heli and Zaunkönig days. 😉
Cheers Doug 😎

Hi Mark,
I've taken to wearing a black suit and dark glasses all the time just to confuse 'em 😉
