Help!
adhesives for foam

with so many kinds of foam, it could be convenient to know what adhesives work on them, and which melt them.
if there is a forum on this, please tell.
thanks
or if there is data on the kinds of foams too.

I use and sell Foam Cure it is the best over all foam glue. IMHO. I also like Gorilla glue. It makes the strongest bonds but the joints are messy looking. Neither of these will attack any foam no matter how you use them. They can be used for gap filling and tight fitting joints.

I also sell and use Bob Smiths Thin Foam Safe CA. I use it for field repairs and some bench repairs where deep penetration into a crack is needed.

Check out www.strongrcmotors.com for those I sell.

Foam tac glue will eat foam if applied in larger amounts.

If you are not in a hurry and can clamp/weight your parts, there are several slow cure/dry choices available at a craft store - Michaels, Hobby Lobby, etc.

Liquid Fusion is a urethane adhesive I have used. Pro- dries clear and has flex. Con - peels when sanded.

Weldbond is a clear drying glue also that looks like Elmers. Pro - very strong. Con - slow to dry if applied to a large area if your foam does not 'breath' (have air paths to the glued surface).

Creatology Foam Glue also dries clear and is similar to Weldbond with the same Pro/Con.

Again, if speed building is not required, consider these. They work fine on Dollar Tree foam board and similar type materials.

Gidden 'gripper' Latex paint/primer makes a wonderous glue for laminating.
Strong and light. Cheap too. ~9$ a liter. Apply it like the latex paint it is.
Needs an overnight dry though, but unlike white glue it does dry.. sans air.

I use UHU POR and epoxy, both of which are quite expensive. (The authentic made-in-germany ones)

Hot glue works very well too. Great for field repairs.

I second using Gripper for laminating. However it does take some time to cure large areas. I'd say plan on at least a few days to get full strength.

a Question about hot glue... Is there different grades of this stuff? I've tried it before but didn't like it. I used the thick rods, with a heavy gun = CRAP!

Then the other day my mate was using this Lipo operated H/King gun with thin rods and that was magic!

Thus my question about "grades".. My local harware only sells the heavy stuff and asking about "grades" just results in a "misty, faaaaaar-off look" in the eye

There are two sizes of sticks, a little over 1/4 in. and a little under 1/2 in. I mostly use the small sticks
I use standard or mid grade of temp. The high temp sticks stay liquid longer for larger areas but may not stay together with a plane left in a hot car in California. Never had this problem up here.
Hot glue works great as hinges on the smaller planes too.
Some people say it's heavy but no more than epoxy. Just use it discretely and not goober it on like toothpaste. I put the nose of the gun perpendicular to the work and put on a very thin bead.
Not good for sheeting, where one end would be cooled off before you got to the other end. I use contact cement for this.
Most of my planes are assembled with it but it's not for everyone.
Hope this helps.

The main drawback to almost all foam adhesives is that they do not sand well. Most are flexible, which is not always a good thing either.

It not difficult at all to find a foam glue. It is impossible to find one that sands well.

Glue Shootout: I only got 8 minutes into this and it is obvious this guy is not an expert. Watching the whole thing would be a waste of time, in my opinion.

Thanks BigTruckDriver!!

I appreciate the time and effort you put into testing the glues and making the video.

I'm "no expert" and you certainly gave me some insights to some of the glues I haven't attempted to use yet.

My exposure so far has been hot glue, Gorilla Glue, Foam-Tac and some foam safe CA.

Thanks again.
