Grizzly is one of the cheaper re-sellers, and I have some of their wheels on machines, one in the ~2500lb range. The guess: Most companies these days sell a range of urethane tired import wheels in the range you describe but not as wide.
First, why not call Devcon, and see what they say? (Yeah, I know they are hard to get a hold of, but they should know their own products) I do not know the answer to your question, but can take a guess. Low alloy: in my apps, the idea was for a flexible, comformable, "grippy" solution. Sorry about my poor memory for product names! They also make a flexane 94, for rigid rubber parts up to, you guessed it, 94 duro. But handy for certain things like making urethane rubber parts. Am always careful to purge the container with argon anytime it is opened. Since the planes only take a dab or 2, still working out of the same (formerly) gallon. Then when i started making the hand planes a few years later, it seemed, like "I've got most of a gallon can on hand, why not try it". Made a set for myself, then a couple buddies wanted them. I started using it about 15 years ago to cast urethane rubber rollers for small 20" import wood planers.
Possibly i should be using one for wood, too, but for my handplanes wood/metal app there are no fail/safe consequences. There are primers for other substrates as well, i believe. To develop a good bond on metal, the metal should be abraded or sandblasted, and primed with the proprietary primer. It can be modified with additives for duro between about 60 and 80. Went down cellar and pulled the product out, it is Devcon Flexane 80 (castable).
