Repairing a light fitting

[D.M. Procida]

A plastic 12v light fitting has cracked. I can repair it with a suitable adhesive, but it needs to be something that won't mind getting quite hot.

How will epoxy resin fare?

Thanks,

I have used epoxy for various things - perhaps not quite as demanding as a light fitting - e.g. washing machine control knob and various switches.

Critical aspects seem to be:

Mix extremely carefully - precise measurement and thorough mixing.

"Bake" at an appropriate temperature and for a long time.

Try it outdoors as the stink of curing/failing epoxy is horrible and hangs around forever.

Well we used to put Araldite in an over to dry faster, but of course it might compromise the strength a bit. Cannot be that hot if the plastic does not melt. Brian

Light fittings would be a thermosetting rather than a thermoplastic material.

Poorly.

not well at all. You can get non-epoxy resins at car accessory shops that handle far higher temps.

If you get one designed for high temperature use, or a metal loaded one, then it will be ok.
