Best glue for plastic?
eznfrank - 7/3/10 at 08:53 AM

I need to glue some small fiddly bits, specifically on my clocks, I have a surround for them but the lenses for the indicators, neutral and headlight are now recessed a it too far so I've cut the lenses off and intend to make a short extension with small piece of polyplumb pipe to bring it up to the back of the recess.

(I know it sounds like that would look cack but it won't be seen)

Anyway, I need to glue the lens to the end of the pipe and then the pipe to the clocks, and I doubt I'll be able to access them ever again if they fall off, so is superglue up to the job? I'm guessing so but also thought of using that plumbing cement stuff that sort of melts and bonds the plastic?

Thanks

Probably best sticking with superglue, the solvent weld plumbing adhesives dont work on all plastics, e.g. abs.

Sueperglue will give of a white vapour that will cover the glass and look crap

Is the Poly pipe a push fit or a solvent type?. if its a push fit type ( feels greasy and soft to touch) then I would say that any adhesive would fail both super glue and solvent type. Just make sure that the pipe is solvent weld-able and you would be ok for either adhesive.
Have fun, David.

I glued loads of bits inside the wifes clocks for her using araldite Instant clear, which is like superglue in that it sets in about 90 seconds but you mix it yourself out of the syringe type things. It's great cos you can mix it up then use a pin to spot it onto the work if required.

The best bit is though it doesn't fog the lenses like superglue will, which is why I chose it for clock-work.

Edited as I had the name of it wrong! : LINK

^^^^

i agree arildite clear would be good i think super glue would be a little to brittle also as well as its white powder side efects on plastic lenzes

also devcon make a good range of expoxis like arildite
