Thanks for the info. Re. Agfa, we've had several examples of PE 49
(double play, 7") which have proven sticky. According to the numbers in
the green leader tape there were two manufactured bad batches at least,
both seemingly bought by us at the same time, circa mid-1988. The
numbers to beware of are 01041 and 15383. All other PE 49 batches thus
far have been fine.

I have never ever seen any BASF tape ever go sticky shed.
BASF is one of the worlds biggest chemical companies.
They have always claimed that they had all the knowldedge in house
together with making all the ingredients in house.
So their position is that due to the above none of their tapes will
exhibit sticky shed as they knew how to avoid it.
AGFA, it is the same except for some batches of Agfa 468 during half a
year or so.
I have only seen one real of 468 go sticky despite having transferred
several hundred such reals over the years.
In contrast it is almost a given that any reel of Ampex 456 will go
sticky for sure.
And that is true over here since so far they all need baking.
