Epoxy or Gorilla Glue
Hi,
Would it be better to use Gorilla glue instead of the epoxy. I am building a ARF and thought maybe the Gorilla Glue would be better. |
RE: Epoxy or Gorilla Glue
Mcoccia,
Absolutely not. Leave the Gorilla Glue alone. Use the epoxy as instructed to. The reason why I advise to not use Gorilla Glue is because this glue expands as it cures. If you do not have the parts properly braced or secured the glue will expand and move the parts out of their properly placement (or alignment). Even experienced modelers have had problems caused by this, and it can be really bad for beginners. This is why I was so adamant about it above. It can cause beginners true fits as it expands. IMHO while Gorilla Glue does have it's uses, replacing epoxy on an airplane just isn't one of them. Ken |

Thanks again:)
Only reason I had asked is I see they use the Gorilla Glue on Foam Airplanes. I am trying to figure why they do this? Is it lighter when it dries? ORIGINAL: RCKen Mcoccia, Absolutely not.

RE: Epoxy or Gorilla Glue
Gorilla glue does not attack the foam like CA does and is lighter than epoxy. The big diadvantage other than the expansion is the long dry time. If you are not used to using gorilla glue, you can lose parts alignment when the glue expands. When using gorilla glue, if it looks like you have enough glue on the part, you have too much. Use as little as possible to avoid the expansion problems.

My recommendation is to use Epoxy unless you have a gap to fill while gluing.

RE: Epoxy or Gorilla Glue
All these responses are correct. Plus, bear in mind that Gorilla Glue is just a trade name for polyurethane glue which is also made by other reliable companies such as Elmer's and some have a much faster cure rate than Gorilla Glue at half the price with no noticeable difference in results. I guess Gorilla Glue was probably first on the market and has become the "aspirin" or "Kleenex" of polyurethane glues.

RE: Epoxy or Gorilla Glue
Another between epoxy and gorilla glue in my experience, is unless you have avery tight fit between the parts, the gorilla glue is more flexible than epoxy when it cures. For joints that are subject to vibration, this could be good, but if its a high stress joint, the gorilla glue may eventually give out. I like the fact that epoxy soaks into the grain of the wood before it cures, making for a better joint.
