DuPont will certainly have the data. As Demon3 says, you will need to contact a real person there, preferably a technical support person.
You get more data if you can find an old technician as often data at that level is no longer in print as the marketing guru's tend to think it looks complicated and scares off prospective customers. They don't seem to consider the counterpoint that those scared of by real data are often headed for a disaster, and without the data to scare them off will charge on regardless. These disasters cost everyone involved.
