CoolChem Cyanopoxy System CA and epoxy in one bottle!

CA is a staple in any modeler's toolbox; it's hard to imagine building a kit without it. That said, it does have some limitations-chief among them is the type of materials it can bond to. What if there was a glue that had the advantages of CA-thin, light, strong, easy to apply and quick to cure-but with the versatility of epoxy? That's exactly what the folks at PRS Technologies set out to create; the result is the CoolChem Cyanopoxy System, and it combines many of the best traits of CA and epoxy into one adhesive.

Have you ever tried to bond metal with conventional CA? If you're lucky, it might hold if the joint isn't stressed, but put any load on it, and you might as well be using grammar-school paste. Not so with CoolChem-the package arrived with several test objects in it, including a pair of lead weights-daring me to test the limits of this glue. Sure enough, after a drop or two of CoolChem and a couple of minutes to cure, the lead weights might as well have been cast as a single piece. I couldn't wrench them apart with pliers!

Not satisfied with the supplied test materials, I set about finding a few challenges of my own. I discovered that CoolChem bonds all sorts of wood-just as you would expect-and plastics are no trouble either. Painted metal? You bet. It also bonds things you wouldn't expect it to-how about a length of rubber tubing? Best of all, it bonds these various materials to each other, and it forms a joint that's light, strong and flexible. Like CA, it doesn't react well to low-- grade foam-I tried! It also doesn't grip wax-impregnated cardboard, but those are the only two things I could find that it wouldn't bond to.

The kit comes with one 15g bottle of CoolChem Integrator (adhesive), one 2-ounce spray bottle of Activator (kicker), one 1 -ounce bottle of Poly Treatment for bonding nylon, Teflon and poly plastics, a 1-ounce bottle of Debonder for separating joints or cleaning up CoolChem residue and a dozen applicator needles. The entire package retails for just under $50. If you want one adhesive that bonds to pretty much anything, give CoolChem Cyanopoxy a try. -Matt Boyd
