RE: [PSUBS-MAILIST] glueing acrylic

["Pierre Poulin" <pipo305@hotmail.com>]

Hi emile,

My friend work at the university here and he glue acrylic all the time. I 
asked him and here is the answer...

You need: a tank about 0.5" deep and Dichloromethane (french word sorry).

How to do: let's say you have a viewport of 8" diameter. you need about 1/8" 
of Dichloromethane on the bottom of the tank, then you drop the viewport 
into the tank so all the surface you want to glue is dipping in the dich... 
wait for about 15 secondes, pull up the viewport about press it to the other 
surface.

Results: My friend says that you may have some small bubbles trapped between 
the 2 parts. As for strenght, he says that it is as strong as a full plate 
of acrylic. he does boxes shape and when they "destroye" them, the acrylic 
almost always break right next to the join. Not the join itself.

Hope it helps!
