What are the limitations on thin-film latex analysis and formation?

I am a physicist trying to learn some chemistry about *latex thin-film formation*. I understand that these films can have different characteristics depending on their drying process, but I have a series of questions on the matter:


* drying latex at temperatures below the minimum film formation temperature (MFFT) results in a brittle or powdery film. What are the uses for said powders and brittle latex?
* what are the limitations on the analysis of these samples (are there limitations to the GARfield NMR)? Are there limitations to the determination of the water content of latex as it dries?
* what are the industrial applications of thin-film latex?


My apologies for my basic questions, but I am reading some [books](https://link.springer.com/book/10.1007/978-90-481-2845-7) and other [texts](https://core.ac.uk/download/pdf/77004409.pdf) regarding the matter and find them deeply confusing from an outside chemistry p.o.v..
