The proper procedure for using bate enzymes is often disputed. Rely on TFL's experience in meeting the goals of your tanning process!
For consistent and safe bating with optimised grain formation use only bates from supply houses well experienced in this field - OROPON (ROHAPON in America, New Zealand, Australia, Japan and Philippines) range of bating agents.
Delime and bate together or delime and bate separately? Deliming to a fixed point and then bating after temperature adjustment is the best way of conducting this process but for practical purposes many tanners add the bate after a short time in main delime float. This is acceptable once a process has been proven and the same parameters are kept each time.
