The problem is they are testing the two adhesives using different methods. They SHOULD yield the same results but then, why did they change test methods? Anyway, there is so much data missing from the two, they are hard to compare. What I have asked for though is comparative impact tests since it looks like the 9380 may be more brittle. In addition, they give two sets of numbers for the tensile shear on 9380, although both are higher than the 9339. But with the few numbers they did have, the 9380 is superior. It is a LOT higher in compressive modulus and 20%better in shear. The Tg (glass transition temperature), is 67 degrees higher in the 9380. They did not give pot life time for the 9380 nor viscosity for the 9339, so we can't tell how they work compared to each other. I'll continue to look and check with some friends to find a more knowledgeable person.
