Myles Posted May 20, 2004 Share Posted May 20, 2004 I need to close a large crack in the hard-plastic shell of one of my autocom headsets - the placcy seems similar to ABS which ISTR being a b!tch to glue. I've already tried 5-min epoxy - didn't do the job (despite being clamped and left to cure for an hour or two). Any suggestions for easily available glues - the dreaded 'superglue' for instance???

Mark Gregory Posted May 20, 2004 Share Posted May 20, 2004 Myles You need a solvent adhesive for ABS. Dichloromethane (Methylene Chloride) or Tetrahydrofuran & Methyl Ethyl Ketone. Sounds as though I know what I'm talking about, but I must confess to reading off the tins!! The Tetra whatsit is the stuff used to glue plastic waste pipes & is avaible from most building/plumbing merchants. Problem is it may be too thick for your crack (as it were!). The dichloro..... is a liquid which is best applied with a small paint brush. I have some dichlor at home in Leek Wootton if you fancy a blast up here sometime. Mark PS: I hope it is ABS, because nylon & polyprop are virtually impossible to glue. ABS is common for electronics enclosures. Link to comment Share on other sites More sharing options...
Myles Posted May 20, 2004 Author Share Posted May 20, 2004 Thanks Mark - I need to try something today though as I'm off on the se7ens list tour of the Scottish borders tomorrow - and this pair of headsets is needed for the passenger (if I find one ).

ECR Posted May 20, 2004 Share Posted May 20, 2004 Might be wort trying hammerite solvent (from Halfords) if you are in a rush. AFAIK it has a high methylene chloride content Link to comment Share on other sites More sharing options...
JAG Posted May 20, 2004 Share Posted May 20, 2004 Hi Myles, any shop that sells 'Airfix' models will sell plastic solvent type adhesive. They call it Polystyrene cement and it most certainly dissolves hard plastics - perhaps ABS??? There is a model shop of the correct type in Studley on the High Street - might be worth a quick blat Justin A closed mouth gathers no foot.

Mark Gregory Posted May 20, 2004 Share Posted May 20, 2004 Justin Good point, why didn't I think of that? Styrene glue will work on ABS, after all ABS is Acrylonitrile Butadene Styrene. Mark Link to comment Share on other sites More sharing options...
Nick Woods Posted May 20, 2004 Share Posted May 20, 2004 I've tried Polystyrene cement with mixed results - if it starts to soften the plastic you'll probably be ok, if it just sits on the surface then it wont stick very well. Gluing hard plastics is very tricky 🙆🏻 Nick Red and Black 1.6K supersport visit Carrotland.co.uk Link to comment Share on other sites More sharing options...
Myles Posted May 20, 2004 Author Share Posted May 20, 2004 Well I picked up some Loctite Super Plastix stuff which consists of an 'activator pen' which you apply to both bonding surfaces and then some solvent that is applied to just one... ...unfortunately, being as my work-piece isn't completely in two sections, it was rather hard to get the fat felt-tip head of the activator pen into the crack - and initial results don't look promising despite the packaging saying that it's fine for hard plastics such as ABS etc... I've left it clamped up and will check later. Seems to have worked, actually... The real test will be how it stands up over the next few days of 'touring'... Keep BC free and open for ALL.

Nick Woods Posted May 20, 2004 Share Posted May 20, 2004 Just a thought - have you tried contacting Autocom ? They might be able to supply you with just the shell so that you can transfer over all the electronic bits yourself.

Support Team Shaun_E Posted May 21, 2004 Support Team Share Posted May 21, 2004 The ear defender is a Peltor unit that costs about £12 - Autocom then add the electronics. You could perhaps do this yourself or Autocom may give you a favourable price to do it for you. Obviously this doesn't help now but does offer you a longer term solution.
