| 1392682 | 2015-01-23 21:51:00 | I normally use Araldite super strength but as you may know it does not do all types of plastic. Selleys also have an "All plastics" glue which claims to bond any plastic type, with the ambiguous quality of being "Strong" - but I have never used that one before. Has anyone here used it? How 'strong' is it? Is there anything better? |

| 1392684 | 2015-01-24 00:11:00 | I wouldn't have a clue what type it is, so I figured something that can do any of them would be a wise choice. It's part of the extendable bit on a pair of headphones. It's plastic, and it's black. That's about all I know... :lol: |

| 1392688 | 2015-01-24 04:07:00 | Isn't the chemical, chloroform bonds plastics pretty well? Chloroform used to be used on Perspex (or Plexiglass if you only speak American), it actually dissolves Perspex and we used to make the 'glue' by dissolving Perspex chips in chloroform, taking care not to breathe the fumes :) The polystyrene glue you get in the model making kits dissolves that plastic, and makes a 'welded' bond, like the chloroform cement does with Perspex. Epoxy makes a surface bond, it doesn't weld into the surface, it's more mechanical and physical , so a clean grease free lightly roughed surface is best. There's lots of info via Google on 'glues'.................info.craftechind.com |

Has anyone here used it? How 'strong' is it? Is there anything better? I have used it and was very disappointed with the results. I followed the instructions to the letter, did not get impatient and prematurely 'test the strength', but the low-stress joint broke the first time I used the item. I normally use Araldite, and the only stronger bond that I have found to date is a two-pot Builders Epoxy from Bunnings. Cheers Billy 8-{) |

| 1392691 | 2015-01-26 08:40:00 | Isn't the chemical, chloroform bonds plastics pretty well? I have a range of plastic-repair solvents in my garage fridge: including Toluene, Methanol, MEK (methyl ethyl ketone), Acetone, Xylol, Acetone-free nail polish remover (that one is good) and Tricoid film cement. If one of those doesn't do the job then Selleys 'All-Plastics' glue, Araldite or CRC Builders Epoxy will do it, albeit with a bit more mess for the last two. I shave a plastic sample from an inconspicuous spot, then see which solvent attacks it best. Cheers Billy 8-{) |
