Franksx2005 Posted October 13, 2010 Report Share Posted October 13, 2010 (edited) As title says, whats the best way to remove anodising? I would like to bare metal my rockman! Edited October 13, 2010 by Franksx2005 Quote Link to comment Share on other sites More sharing options...
forteh Posted October 13, 2010 Report Share Posted October 13, 2010 Caustic soda bath will remove anodizing, results may vary though and the aluminium will be a dull grey colour underneath. Thats a lot of caustic soda though, certainly wouldnt want to do it myself! Quote Link to comment Share on other sites More sharing options...

Im pretty sure you should be able to powdercoat over anodising, after all its only a coloured oxide layer. Blasting is another option, depending on how much you want to spend though, blasting with shot will possibly affect the material (wearing some away), alternative blasting medias are stuff like vapour and walnut husk which are much gentler on the base material but more expensive. I would speak to the powerdcoaters and check about the anodising. edit: These people state that anodising is a good preperation treatment for powdercoating, Im sure you must be able to wash it down sufficiently to coat.

I was about to say that, anodized frames seem to have quite a rough feel (compared to not) and the powder should stick well to it. Quote Link to comment Share on other sites More sharing options...

Rob Leech Posted October 14, 2010 Report Share Posted October 14, 2010 I was about to say that, anodized frames seem to have quite a rough feel (compared to not) and the powder should stick well to it. Would get it shot blasted my self maybe glass beads? cheap, soft on the material and eco friendly for all who care. Pretty sure that this is a surface prep before anodizing, either shot blast or chemical etching. If you look at the Bjorn frame (still cant spell i think ), the graphics are nice and smooth where as the rest of the frame has the grainy affect your talking about . Bit of a pointless post really, but thought id share the knowledge. Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
