Good protection of the hides requires addition of the fungicide in a manner that assures its maximum transfer to the hide from the liquor to which it is added. Experiments with TCMTB labeled with radioactive carbon-14 showed that uptake of the fungicide by the hides was greatest when the TCMTB was added as soon as practical in the tanning process. When TCMTB was added to the chrome liquor at the beginning of tanning, over 90 percent of it was taken up by the hides, while adding the fungicide three hours af ter the start of tanning reduced the uptake to 77 percent. Exposure of treated hides in a tropical chamber showed that the duration of mold resistance was directly related to TCMTB uptake. Hides containing 100 ppm of TCMTB remained free of any visible fungal growth for over 25 days under these severe conditions.
