HELP fusing two pieces of plastic together! PICS

[Gradywhite3535]

Hi all, I need these two pieces to be attached. I've tried a few types of epoxys and other glues with no success. Any ideas? Theses pieces will be under water while I'm vacuuming and only while vacuuming. Thank you

jb weld

Which one? Got very much different products https://www.jbweld.com/collections/all

Get a commercial hot glue gun...not the type they sell at the dollar store.

Sorry the link I attached would not work


good luck,

Mike

I agree that jb weld is the strongest but I tried the red and black bottle of jb weld and it doesn't stick to plastic(at least the piece I have). I bought the blue bottle and that just seals/patch things). I will look into the hot gun. All iideas welcomed? Thank you

3M 5200 Marine adhesive sealant .
The best stuff out there for underwater use.
Have always used this on the sterns /hulls of fiberglass boats , and if something ever needs to be removed after using this stuff ..........it usually pulls the gelcoat and some fiberglass off with it ! Have used it with lots of plastic transducer installs and it adheres very well to (dry) plastic .
Yes, its that good . Just give it the proper time to cure properly .

Have you tried pvc glue?

 

[richierich]

yeah pvc glue would be my vote. Just make sure you use the purple primer first. Then the pvc glue. They are usually sold in a package together made by Oatey.

All very good ideas, I think I'm going to try the 3m. I have some on my boat so I'll give that a go and post back. Thank you guys again
