Gluing Perspex etc
Last August there was a thread about cutting & gluing acrylic sheet.
I've found a product from a model makers shop which glues acrylics eg Perspex, Plexiglass, Lucite etc to itself or to PVC, ABS etc. The product which can be bought in little bottles of about 50ml for around £2 is called "EMA plastic weld" and it does work - I used it to mend the acrylic parts of an old washing machine timer. If anyone is interested in obtaining it they can ask a local hobby shop or contact the manufacturers: EMA Model Supplies 01932 228228 which is at Shepperton, Middlesex. No connection with me! Joe |

Re: Gluing Perspex etc
Yes, I've used it for many years. It is basically the same solvent as used in ICI's Tensol cements. Find these from craft suppliers or model shops. Tensol 10 is a mix of the same solvent with dissolved clear acrylic - this thickens it up into a paste but whether used as paste or as straight liquid, both work by melting and fusing the surfaces together and have a very short active time. The non-viscous liquid is workable only for a second or so. It can be applied using a syringe for accuracy, or a small watercolour brush along any edges to be joined. Because it is thin it will wick into joints well provided the two surfaces are in intimate contact. It doesn't gain max strength for some hours.

Re: Gluing Perspex etc
With some googeling I learnt, that this
"glue" is Methylene Chloride. "Good old days" this was used as a paint remover and th clean paint brushes. As a glue it is good for a lot of plastics*, but You should use a lot of care to avoid drops falling on a shiny surface. This will result in a ugly stain. Perspex (PMMA) can react to solvent vapors developing small cracs named "crazing". For that reason Plexiglas should be kept away from areas where this glue is handled often (or other solvents like Acetone, Nitro thinner etc) Georg * Not for PA, PE, PP, PTFE |

Re: Gluing Perspex etc
Ditto,
Get it from a local plastic fabricator, along with offcuts....

Re: Gluing Perspex etc
Methylene chloride (the solvent used in Tensol) is more commonly known as dichloromethane. Incidentally, I use chloroform as a solvent for perspex, though I keep the door open while I'm doing it! I have never had a problem getting it from my local pharmacy - the trick is to ask for industrial chloroform, and explain why you want it.
