Beacon Foam-Tac Glue bonds Depron, EPS, EPP, XPS, EPO, and many other kinds of foam quickly & cleanly. It does not attack/melt/dissolve foams, and when dry it remains flexible and clear. It's also great for bonding carbon fiber.
SUPER STRONG BOND - FOAM-TAC creates a super strong bond that is like welding the foam together. Make a Butt-Joint and you won't be able to find it later, stronger than the foam itself once it's cured.
LESS IS MORE - Always dries clear, simply apply a thin amount of FOAM-TAC to one side of the joint and gently press together. Pull the joint apart then press together again. That’s it. You don’t have to wait for the glue to get tacky.
My [note: this is filadelfosrc writing] own personal observations about Foam-Tac:1. It's a thick clear goo, reminds me of shoe-goo in it's consistency, but a little thinner.
2. Even though it's thick, when you pull the bottle away, it doesn't have any stringys to deal with.
3. Once bonded, you will not see the seam line & have no idea that it was ever two separate pieces.
4. Even though it forms a strong & permanent bond, the glue remains flexible & clear. I have used it to re-attach a broken aileron, and the aileron
functions just as it did before re-attaching (I actually glued the aileron straight onto the wing, knowing that it would still flex after Foam-Tac cured).
5. The bottle instructions say it takes 10-20 minutes to form a strong bond, but in my experience it happens in as few as 10-20 SECONDS, so that may be a typo.
6. You don't need to use much glue at all, I use far less of it than if I were to use a foam-safe CA for the same task.... and there's no need for any
