Re: [PSUBS-MAILIST] glueing acrylic

I worked for the university of Colorado for a few years and we used lots of Acrylic for building test models of buildings and Dams and just about any thing that needed to be built. We used a glue called PS 30 and it was very strong. It's a two part glue and if the two components where not in just the right amount it would craze. But I never saw any of the joints separate. However,,,,I would never ever consider using anything but a full piece for a view port. DJB

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!
