FOAM-CURE™ is a silicone based adhesive that works very well on EPP and EPO foams. It is crystal clear and cures to a more flexible consistency than CA. It is, however, not instant bonding like CA and there is no accelerator to speed it’s curing. To obtain a faster initial bond when bonding two pieces, FOAM-CURE™ can be applied to one piece and after the two are joined, they can then be pulled apart. After letting it air dry for about ten minutes, FOAM-CURE™ will act like a contact cement when the parts are rejoined, resulting in enough tack strength to allow the next steps of assembly. Full strength is reached in 10-12 hours.
FOAM-CURE™ works with all foams, and will actually bond most other materials. It will bond wood and plastic to foam, and is a good canopy glue. FOAM-CURE™ does not, however, cure flexible enough to act as a hinge for aircraft control surfaces. Its limitations occur when bonding large areas of two non-porous materials. FOAM-CURE™ requires exposure to air for drying. If one tried to bond, for example, a half-dollar coin to glass, over 90% of the adhesive would never cure, since the solvent it contains would have no where to evaporate.
This glue is manufactured by Bob Smith Industries. According to their excellent Web site, you can thin it with ethyl alcohol or with denatured alcohol, aka methylated spirits. I have done so, and it works well. BSI say the shelf life is two years, but they don't make it clear whether you can make it last longer by thinning.
Thanks lauriec. That answers my first question about shelf life. I am looking for an adhesive to stick carbon fiber to foam and mylar film to an air frame before heat shrinking. Can anyone help with these two applications with this adhesive?
I like that glue... I use UHU Por, because its a very good product, but, the uhu is after drying always sticky... Now i have tried this glue from HK, and, this is very good, i used it with Epo/ePP, Depron, XPS.... Works very fine and is strong and is agter drying not sticky... Perfekt also for clear canopys....
Any experience with EPO foam. I have a EPO made Dynam Hawk Sky.
Also any idea about the storage time, I mean does it remain in its form over 6-12 months or dries very quickly.The reason I am asking this that it takes around 1.5 - 2 months shipping to India and I want to keep things in reserve.
This has become my favourite glue Works really well on Epp, glues carbon to Epp and I have tried some test pieces of Depron and coreflute All good
Takes 12 hours for complete cure but will hold parts in 15 mins or so and is easy to use
Hiko, I'd like to hear more about your test on coreflute. My own test did not work out so well. The reason (for my failure) is clearly given in the description. I was gluing tow 1"x2" flat pieces together, so most of the glue didn't really cure. It might work better for exposed pieces (I will have to try that)
I used it to put a corflute kf2 piece on the front of my epp simple delta mainly to stiffen the front
Worked well and I use this glue for just about all the glueing on my foamies now
This is great Glue. Used it to glue1.5 mm carbon fibre rod to LE and had no difficulty getting the glue on one metre rod and attaching before cure. Did not even have to clamp it to stick in place and any overspill is easy to clean off the rod.
