Original poster: David Speck <Dave@xxxxxxxxxxxxxxxx> Jeremiah, Just for fun, take a look at the chemical structures in: http://www.phys.hawaii.edu/~sattler/Publications/pdf-files/NewAspects%20of%20growth.pdfand note the chemical analyses of coal tar, coal pitch, and related compounds in:
http://www.atsdr.cdc.gov/toxprofiles/tp85-c4.pdfTo be honest, the potting material in NSTs is more accurately pitch, rather than tar.

Original poster: tesla popp <teslas_lab@xxxxxxxxx> Then with that in mind, what IS in tar that makes it biologically harmfull to the human body? I see I was wrong about it being PCB's, another chemical that becomes active/released when the tar is heated? If anything in tar was so deadly, I surely would be feeling the effects by now :P If you know why they say tar is dangerous, speak up... Coiler Forever: Jeremiah Popp
