I'll see if I can locate the article I read, it was a number of years ago in Popular Science, I believe. It was about the large number of "organic" compounds used in coatings on such things as film, audio/video tape, CDs, and of course lenses. It even had some amazing photos of "fungus at work" on these coatings. It caught my eye because I had had a stack of 5.25" floppy disks die of "mold", which I thought was wierd. I had not heard of the SMC coatings being ceramic, doesn't sound like much of a food source for fungus. But then there are cockroaches that eat plastic. :-(
