Man, $13 after shipping for a 5oz tube

worth every cent to have on hand for any acrylic project.
 
Hi all,

Weld on #13 does make a fairly strong bond between PVC and acrylic, but it will craze extruded material, it is messy and because it is mostly solvent it makes a ton of bubbles when the solvent evaporates away. Generally, I hate the stuff. It really only works well when you have extremely small gaps to fill (less than 1/16").

Anyway...

Super Glue makes a new adhesive called "plastic fusion". It is actually acrylic monomer and a peroxide catalyst. It is packaged like epoxy and located near the epoxy in my local Lowes.

It smells just like weld on #40, but it is a much thicker (almost pasty) material and cures much faster than #40.

I have only used it once, but it seems to work quite well. I would rough up the parts with a bit of sandpaper to make sure it gets a good grip, but the cured material is hard and strong and is acrylic. The only real drawback I can see is that it is pale yellow in color, but for the upsides, I can live with it.

i use weld-on 4052. i did a test with pvc->acrylic with #16 and it did not hold at all. dropping the test piece (an elbow glued on it's side to a small square of acrylic) just a few inches broke them apart. so i got the 4052, which is a 1-part that comes in a can. works wonderfully except that it is a nasty yellow. forms some small bubbles, but *nothing* like #16 does.

mcmaster has 16 and 4052, though a search for 'weld-on' does not bring them up. look on page 3229. shipping is cheap from mcmaster.
