When using our TanX AL-6 or TanX PR-3 tans, we recommend that the float be 350-375% of the weight of drained, shaved hides. To determine the amount of water needed in gallons for a 350% float, use the following formula:
Hide weight times 350% = xx, then divide xx by 8.33 (which is the approx. weight of a gallon of water)
For example, 150 pounds of hides using a 350% float would be:
150 x 350% = 525 / 8.33 = 63 gallons
Or, you can change the % into a decimal:
150 x 3.5 = 525 / 8.33 = 63 gallons
When calculating a %, use the % key on your calculator. We recommend rounding up to the nearest gallon.
- If using a static tan, use a float closer to 350%, you don’t want to pack the bath too tight, as the hides will need to have room to be agitated.
- For a wet drum tan, you may want to use a little tighter float. You will know what % float works best with your particular wet drum process.
- We do not recommend running a float less than 330%. Also, if you use a float greater than 400%, the tan will be too diluted.
- Shaving the hides prior to tanning will use less tan (less weight) and will also help the tan to penetrate better (being thinner).
