Hello! Looking for glues!

Post by UltimateSteve » Wed May 18, 2016 10:24 pm

Hello. My (user) name is Ultimate Steve. I first got started in Water Rocketry a few weeks ago, and have built two water rockets. I am building a third, bigger one, but it's progression is being limited by two factors:
1) The current rate of soda consumption in my household (I need more 2l bottles)
2) I don't know what glue to use for PET plastic.

Number two is my main problem... In order to make "spliced pairs" you need to glue two bottles together. I have done some searching, and I haven't found any glues that will work very well on PET plastic. I know about PL Premium and Sikaflex-whatever, but I don't think either one is sold anywhere near where I live...

Any Suggestions? (for the glue)

I have, in the past, used loctite marine epoxy. It was very strong, and as far as I'm aware it never sprung any leaks. I used it up to 150 Psi? I think. The main reason people would use sikaflex or pl premium, to my knowledge, is because it allows for the splice to flex, as the glues do not dry rock solid. i would honestly recommend you go out and find a bunch of different adhesives and just test them, and then report back to us to share the love. I know there are a lot of people out there in the same situation as yourself.

Question 1.) Depending on where you are (i.e US) you can get grocery store brand seltzer or tonic water for $0.80 per bottle.
Question 2.) PL Premium construction adhesive located in your local hardware store (not sure about ACE hardware, some places don't carry it) is a very good glue. Here is a link to a tutorial to get you started!
