Re: Joining polycarbonate /Perspex panels to make a case?
I have a 57ml ( = 2 fl.oz) bottle of "Plastic Weld" cement that I got from a stand at a model railway exhibition a year or so ago. It consists of Dichloromethane (Methylene Chloride), and Perspex is one of the plastics that it is stated to be suitable for welding. I have only used it on Polystyrene.

It was mentioned in Cyril Freezer's book of 1001 Model Railway Tips.
Even when it was written it mentioned you had to sign the poisons register to obtain it. It can be potentially deadly even in the right hands! |
Re: Joining polycarbonate /Perspex panels to make a case?
You've reminded me there's a bottle at work, originally for that purpose. It's probably been there 30 years. My boss didn't know what was in it, and gave it a sniff...
[Off topic - of a similar vintage we also had several brown 1 litre laboratory bottles of Gallenkamp's finest 'Oil, Olive B.P.'. These were surplus, and I've been topping up the wife's flashy 'extra-virgin' bottle when her back has been turned for the last year or so. She doesn't seem to have noticed we have Italy's answer to the magic porridge pot.] |
Re: Joining polycarbonate /Perspex panels to make a case?
A few points here. A bottle of chloroform that is 30 years old could have degraded and/or evaporated during that time. Chloroform is usually stabilised with ethanol or amylene these days to prevent degradation. If your boss was daft enough to take a sniff of something in the bottle without knowing what it was, he is a fool, to say the least. Was there nothing on a label to inform him?
With regard to the poisons register, I don't think there has been such a thing for some time. There again, in my day-job before I retired, I was in a research group at Imperial College, London and we used quite a lot of chloroform - there again we were in an academic environment and educated people. If I were you, Marc, I wouldn't use that Gallenkamp olive oil for anything culinary. Again, after 30 years it has a good chance of having degraded by oxidisation or polymerisation. The "BP" designation means that it was meant for pharmaceutical purposes anyway. "BP" is "British Pharmacopia" and indicates that. On principle, I wouldn't take anything out of a workshop or laboratory and use it for a culinary purpose. How do you know that it isn't impure? That might mess up any experiments that you might use it for, but consuming it might do a lot more damage. Colin. |

I am fairly sure it won't work with Polycarbonate. |
