Yes

direct kodak quote for infrared 70 mm
The film has a 4-mil (0.101 mm) ESTAR Base with a fast-drying backing.
that means it has no back coating.

TMAX 120 size films have the capablilty of being retouched. They are made
with a coating on the base side that is gelatine.

My guess is that this time of year when the humidity level is lower, the
water
doesn't have as much time to run off the film and drys to fast.

In the tmax film, the residual water is diffused throughout the film base
by the gelatine layer an is less noticable.

That's my theory
