Gluing washing machine plastic?
The clips that hold the front (pull handle) onto the detergent dispenser
tray have snapped off! There's sufficient overlap that I expect that I can glue the drawer front back on. Can anyone suggest what type of plastic is used and what glue(s) may be suitable? Superglue won't stand the humidity and contact adhesives won't work because the components need to be slid together. -- Jan Speaking from a Virtual Pleasure Garden in E1 |

Try to avoid the quick-setting version, and thoroughly clean the plastic surfaces of soap, grease and so on before you start. -- Frank Erskine |

Is there also a case for roughening the mating surfaces with sandpaper befor applying the glue? |

The handle of my Dyson recently broke and rather doubtfully, I bought a tube of Ever Build Plasbond 65, Liquid plastic So far it seems to have worked in this high-stress situation, but I guess results very much depend on the plastic in question.

I've found Evostick Serious glue sticks most flexible plastics pretty well. Takes about 24 hours to set fully, though. -- *Money isn't everything, but it sure keeps the kids in touch.

There will either be an acronym: "PP" is polypropylene, or a numeric code (Google it). Knowing this, you can find a solvent adhesive that will stick it. Polystyrene is easy, ABS is easy if you get the right solvent (MEK alone won't work), PVC is poor mechanically but workable for sealing. To be honest, these solvents are all awkward to get hold of, so you're likely to end up using the same adhesive for ABS solvent weld plumbing from a plumber's merchant, just because it's all you can get. Not Travis Perkins though, as they're four times the price of Toolstation! Otherwise a good epoxy. Roughen the surface for a key first, try to add a mechanical brace with aluminium strip and self-tappers first. |

Actually I have found the epoxies dot stick as well to plastic as : CAR BODY FILLER ...which I used to repair a washing machine drim that sheraed its blocks off. I glued em back on ! I am not saying it is a perfect joiunt by any means, but its better than epoxy. Almost nothing works well with polythenes. |

Anything that solvent welds easily and compatibly with polystyrene (so ABS too) is going to bond pretty easily with "GRP" and its polyester or styrene-based ilk. However if your base material is from that group, then you can probably just solvent weld it easily anyway. |

This is quite easy if you have a hot-air welding gun - people who do car bodywork do. Many years ago I had to construct a small plating line from PP - the tanks were about 75 cm cube, IIRC. I tried a hot-air gun but it slightly charred the PP; not sure if this would have caused a joint to fail, but with lots of chemicals and v. hot water involved... Got a cylindre of nitrogen and used that - perfect joints every time (after a bit of practice). Not really viable for home use though. -- Peter.

I don't know the differences of temperature and airflow in detail, but you can repair car bodywork (bumpers etc) with the real one in a way that just doesn't work when you try to hack it with a paint stripper or a heatshrink gun. |

I held the two broken ends over a small gas flame for a moment until the surface melted, and then pushed them together.

I actually examined a previous version of the same washing machine assuming that the changes would just be the usual marketing inspired bollox, I've just examined the actual washing machine and find that they've actually changed the tray from polypropylene to "Euro Carboran". I've been Googling carboran/carborane but haven't found anything useful abooout glues or solvent welding. I've abraded the underside of the real item and applied a piece of scrap ABS to it with epoxy resin. I'll see how well it's stuck in the morning, If the joint fails, I'll pick up some Serious Glue from Robert Dyas and try that.
