Plastic Glue Question....

[ctva]

Through my own careless action (bumped it), I have broken the plastic control housing on my Navico WP100 wheel auto helm. The question is, what is the best glue to put the grey casing back together as I am unsure as to what the type of plastic is to match it to either super glue, epoxy, hard plastic glue or something else? Any assistance would be greatly appreciated.

Should be OK with Areldite type epoxy.

Try Plastic Magic first.

What sort of plastic is it?

Just in case, does anyone have an old one they no longer use?....

If you examine the piece carefully, you'll probably find a triangular recycling logo tucked somewhere. This should have a number which corresponds to the type of material. Mr Google will take you from there. Unfortunately not all plastics are recyclable (so some don't have a number); some others, less commonly recycled, fall into a catch-all category 7.

Many plastics simply can't be glued satisfactorily, with epoxy or anything else. Have you considered plastic welding?

Good idea Mr macd. Will have a look tonight when I go back to the boat. It is the same material that the onl ST 50/60 Raymarine display units are made from as well so may have a look on them.

If worst comes to worst, the plastic welding with a soldering iron will be the order of the day.

Anyone selling an old unit..???

I didn't for one minute think it was like a car bumper, I just wondered if the bumpers welders expertise could be utilised on your piece of plastic.

Sorry!

good idea though, I just wish plastic was simple like wood or metal!

Cyano AKA superglue often works well, it is at its best on thing cracks.
So maybe try that first.
Things like epoxy will fill gaps, so will take up the slack when you scrape the cyano out of the crack....
Some plastics can be solvent welded with the stuff they sell for plumbing waste pipes and so forth, or 'solvent Airfix glue'.

Sometimes adding some reinforcement instead of relying on a small bond area is the way forwards.

Evostik 'SERIOUS GLUE' works on both hard and soft plastics,comes in a good size tube, and have had good results with it.If the space allows a gash piece of plastic to be used as a backing across the crack then that would be much better than a simple butt joint.
