Glueing PVC with Acrylic

Hello. What glue should I use in attaching PVC with acrylic? I am making a kalk reactor and CA reactor. I would like the glued seams to be leak-free.
 
Use #40, it'll work much better than #16 IMO. It stinks, though, better open a window when you mix it up!
 
I have used Weldon 16 for non-pressure applications.
Yep, even the linked chart shows Acrylic to PVC (rigid) having #16. I picked up a reactor loaded with media (full ARM jug) & water = no failure.....not that I'd recommend that :D

From IPS -

16 - Fast-setting, medium bodied, high strength acrylic cement. Also bonds rigid PVC, ABS, styrene, butyrate, polycarbonate to themselves and each other, as well as other plastics and porous surfaces.

Low pressure apps such as skimmers (unless weight bearing) & reactors. Tank plumbing? #40
 
Hi all,

Weld-on 40 would be my first choice, but I have also used a product called E6000 for this purpose. It is available at Wallyworld (WalMart) and craft stores like Michael's.

It has an odor of acetic acid when it cures (like silicone.... I suspect it is just silicone with extra additives), but it sticks very well to plastics. It is very thick, very sticky and makes a very strong bond. It does take a little while to set up, so you have to be able to clamp the parts if they won't naturally stay in place.

I would not use this stuff for high pressure applications, or where a major leak could cause a flood, but I have used it on calcium reactors and many in-sump applications.

I also don't know anything about it's long term (years) durability.

Hi all,

Just another note about IPS's recommendations.... They are very general and are often missing important qualifying information.

For example... they recommend only #40 or #42 (the same stuff, 42 just comes loaded in a caulking gun type cartridge) for aquariums, suggesting that it creates the strongest bonds. This is only true with correct surface preparation and annealing (heat treatment) of the entire project after the adhesive cures. FWIW, these are not really DIY type materials.

#16 works very well in this case since the solvent softens the PVC a bit, making a very strong bond. Just be careful on crudely cut acrylic (the heat of cutting causes internal stress)... the solvent in #16 can cause it to craze.
