This has no resemblance to the Tetenal product. It is exactly the same Kodak product used in large roller-transport units. I use it in my drums of all sizes (including 30x40), or I could use it in any automated roller machine. For the latter usage, they recommend a stabilizer. I dev at 30C for 2min.
It works wonderfully and reliably. I never had luck with that Tetenal "room temp" nonsense.
