Comparing Adtech 820 to Pro-Set LAM-125

I have been comparing the claimed tensile strength of Adtech 820 to Pro-Set LAM125.

Pro-Set claims that the tensile strength of LAM125 resin with LAM224 hardener is between 10,900 psi and 11,400 psi, depending on cure schedule.

AdTech claims that the tensile strength of 820 resin with 822 hardener is 25,514 psi after complete cure.

Both claims are based on neat resin sample only.

Is Adtech really that much stronger in tensile testing? The claim for Adtech 820 resin with 824 hardener is 45,000 psi.

Is the Adtech epoxy really between 2 and 4 times as strong as Pro-Set epoxy in tensile strength? Is there some way to independently verify these claims?

If the Adtech epoxy is so much stronger, why have they not completely taken over the market? I am ready to order some, but I just can’t help but wonder if I am reading these compared claims correctly.

Your link is to axson , not adtech. Axson is a very good resin system, producing the stiffest parts I’ve made. It’s expensive though.

I guess adtech has merged with axson .

I appreciate the response. I have read positive reviews about Adtech 820. For the project I am working on, price is not important. It’s a small, high value product that uses very little resin.

Have you done any testing to evaluate the strength of the final product made with Adtech compared to other epoxies?
