ezgonzo Posted November 5, 2011 Report Share Posted November 5, 2011 (edited) i've stripped a few things with coustic and the results varied each time, some items took only a few seconds before the anodizing was completely dissolved, other things like a middleburn bash ring took a lot longer in a much more concentrated mix, it all depends on the quality of the anidizing, i have a feeling that your onza has a very dense coating, if this is the case then it will need to be exposed to a higher consentrated mix for a longer period, dipping the whole frame would be the best way instead of brushing it on but obviously that would require a large amount of coustic and the fumes that it would give off would most likely kill you if you where to under go this method in your bathroom without any safety gear. hope that helps. ez.

MonsieurMonkey Posted November 5, 2011 Author Report Share Posted November 5, 2011 I thought about dipping. But I reckon the headtube and BB threads will get demolished. I'm gonna have another go next week. (So lame having all this stuff at home) I'll try a more concentrated mix. Quote Link to comment Share on other sites More sharing options...
piperfraz Posted November 7, 2011 Report Share Posted November 7, 2011 So which one works on which? (Nitromorse, caustic soda for anodised or painted?) What would I need for my T-Pro frame? Quote Link to comment Share on other sites More sharing options...

Tpros came in both painted versions and anodised version. Get a picture up. Quote Link to comment Share on other sites More sharing options...

dann2707 Posted November 13, 2011 Report Share Posted November 13, 2011 Get a closer picture of it up. You didn't really pick the best picture for us to tell did you haha. And Caustic Soda for annodising and Nitromorse for painted finishes.. Quote Link to comment Share on other sites More sharing options...
Ali C Posted November 13, 2011 Report Share Posted November 13, 2011 looks painted to me, the way the cable has rubbed though looks more "painty", looks like you can see undercoats of darker colours too. Quote Link to comment Share on other sites More sharing options...

piperfraz Posted November 17, 2011 Report Share Posted November 17, 2011 Started rawing the frame with nitromorse tonight, seems to be working fine, so it's definitely painted Happy days Quote Link to comment Share on other sites More sharing options...
winchman Posted November 18, 2011 Report Share Posted November 18, 2011 Please wear gloves and goggles, this stuff is really toxic and will burn you. Caustic causes the skin to defat, basically it turns your skin in to soap. Have you not tried a local furniture strippers or Chrome platers? these should be able to do it for a few quid. Nitromorse the one you nuterlise with Meths not water is the best. Some finishes are very resistant and can take a few goes This is what the bike factorys use to strip and badly painted frames etc http://www.pcpconline.com/ Oh have a look here before you mess with chemicals at home http://www.kenwoodward.co.uk/ Quote Link to comment Share on other sites More sharing options...
piperfraz Posted November 29, 2011 Report Share Posted November 29, 2011 I'm about half way through doing this, except it seems to take loads of coats and crazy scrubbing. I've done about 10 coats or something now, and I'm using wire wool to get the paint right off, then washing the mess off. Am I doing it right?

With the correct stuff it should come off first time, you have to be carefull using wire wool as you can get electrolitic reaction between the metals causing staining and corrosion, I would use a scotchbrite pad or pan scrubber.

chris4stars Posted November 29, 2011 Report Share Posted November 29, 2011 leave a decent coat of nitromors on for a good half hour or so - so alot thicker than just painted on before using a scotch pad (which is alot better btw) use a sharp knife and gently peel the paint off as you would the skin of a veg of some sort do this until it almost gets down to the metalwork itself then use a credit card or something plastic/bendable/stiff to scrap the paint off without damaging the frame after that then use the scotch pad - with the new nitromors, you'll be there for literally days on end doing the whole thing with a pad Quote Link to comment Share on other sites More sharing options...

(see the inspired skye post in bike pictures section) - piperfraz, i have listened to advice given to me (by more experienced members) and have been stripping my frame over the last week and the pics suggest i have an idea of what to do the 'old' nitromors contained the recently banned chemical that actually made it work well. the new stuff is rubbish and does barely anything. dont take your frame to any stripping tank unless you are 100% sure that the chemical they use wont react to the frame material. some use acid, others use a nitromors based chemical (its partly why frame warrantys are voided when the bike is repainted) Edited November 29, 2011 by chris4stars Quote Link to comment Share on other sites More sharing options...

winchman Posted November 30, 2011 Report Share Posted November 30, 2011 It might be correct for the frame but it also needs to be the correct stuff for the coating applied to the frame Nitromors is possibly only available to professional strippers and no longer thought suitable for DIY use due to increased health and safety not just for the user but the environment Quote Link to comment Share on other sites More sharing options...

Nitromors has changed, an active ingredient has been removed. Luckily, you can still get the old stuff sometimes. Dunno what a professional stripper would do with it anyway, it totally burns the skin and they have more on show.

winchman Posted November 30, 2011 Report Share Posted November 30, 2011 Do you ever read an entire thread, to check that what you're posting isn't complete bollocks? Well thats very friendly of you isnt it Nitromors has changed, an active ingredient has been removed. Luckily, you can still get the old stuff sometimes. If you bother to do your homework you will find that Nitromors started to sell a new water neutralised stripper along side the meths neutralised one, then slowly removed the meths one and only made it available to commercial strippers Dunno what a professional stripper would do with it anyway, it totally burns the skin and they have more on show. Suppose it could be a fetish thing... professionals who do this either use enclosed tanks Like this http://www.surfaceprocessing.co.uk/for-industry.html Or wear full protective equipment as a last resort. Nitromors is not the strongest compared to industrial strippers. I think the issue here is we are tryig to help some one who is having problems stripping a coating from a frame, in my experiance its far better to let a commercial stripper do this as they have access to far stronger chemicals and have the relavant experiance to strip it with out damage. All over the counter chemicals have been replaced or removed over the last few years due to increased health and safety. As I work in industry I know this for a fact where as your average man in the street just sees products dissapearing from the shelves. Personally I would just post it to a stripper as the cost would possibly be less than it would cost to buy the chemicals required. W had to get a few thousand frames stripped before we bought a machine to do it and we paid less than £1 each as they will fit on the conveyor system with other bits they are doing. 1 Quote Link to comment Share on other sites More sharing options...
