Thin acrylic glue

[Martin Brown]

Any suggestions for a thin fluid solvent based acrylic glue to mend some damage on a largish 5cm diameter Perspex pipe for a science demo.

The end got bashed and it would be expensive to replace. The repair must be waterproof and preferably clear and same RI as perspex.

I am tempted to try petrol or pet ether and hope that the end of the crack doesn't run. Basically I need a low viscosity solvent glue that will go into the fine crack by capillary action.

Most acrylic glues feel too thick for this job. Any suggestions?

Chloroform. You can weld perspex with it, so if you run some into the crack it should weld it closed.

[jrwalliker]

Yes, chloroform should do it. The viscous perspex glue is often made by dissolving perspex in chloroform. Avoid acetone at all costs - it will make the perspex craze.

Dichloromethane (methylene chloride) (the active ingredient in old paint remover.

Use a solvent, not a glue

Any easy way of buying this - as modern paint removers don't do what they say on the tin...

I've used this on clear acrylic preety good stuff but expensive.

Predominantly methylene chloride as suggested by another poster. Should be fine (don't inhale!)

Slightly eccentric cart system but their products are good.

+3. I've used chloroform many times on perspex: let a little run into the joint and hold it closed while it melts the surfaces together and evaporates. For a thicker, more 'gluey' approach, dissolve some perspex shavings in it.

Vastly safer than chloroform. Can one even buy chloroform these days?

Found it on ebay, not Amazon though

[meow2222]

The seller grossly understates the dangers, perhaps to a similar extent to that handyman that removed the panel keeping kids from a 60' drop. I've no great concerns handling conc acids, but am very wary of chloroform.

Why?

Yes, so?

This is dangerous;

Compared to, say, chlorine trifluoride;

Chloroform is about as dangerous as peanut butter.

(Perhaps the fact that I have a (bio)chemistry degree biases my feelings in the opposite direction to you?)

Try a model shop which caters for serious makers of plastic kits; - 'Plasticweld' or something like that.

the dangers of other substances tell us nothing about chloroform.

Er, no. Peanut butter is pretty safe for kids to handle. Chloroform is a vo latile toxic carcinogenic general anaesthetic. It may not be a problem for folks with the necessary knowledge, but to put it on public sale without ad equate warnings is irresponsible.

I've worked with it occasionally years ago, but no way would I sell it to a ny & every random stranger. Perhaps you would.

When was about 14 used to get ether by the half litre from local chemists, best switch cleaner about, used to ask that I get it late in the day becaus e decanting it would stink the shop out.

Chloroform looks bargain priced aginst cost of ether on ebay nowadays...
