Application recipes
Application recipes For an optimum area yield before bating operation a preliminary deliming of the skins and hides with a proper deliming agent like Defetcal DK-29 is advised. Best results are obtained when working at 3℃ bath temperature. Depending upon the raw material and the processing conditions the optimum dose changes between (as a guide on pelt weight):
For sheep and light weight calf skins after deliming: 0,3 – 0,8 % Derobaz-T DK-2000, mean processing time 25 – 45 minutes.
For garment calf and cow skins after complete deliming: 0,7 – 1.5 % Derobaz-T DK-2000, mean processing time 90 – 120 minutes.
For goat skins after deliming: 0,3 – 1,0 % Derobaz-T DK-2000, mean processing time 50 minutes.
For upper leather cow and calf skins after deliming: 0,3 – 0,7 % Derobaz-T DK-2000, mean processing time 30 minutes.
In double face manufacture: in the degreasing bath, by soda ash addition pH is adjusted to pH 8,2 and then 0,2 – 1,0 g/l Derobaz-T DK-2000 is added, the processing time depends on the effect required.
Packaging
25 kg in kraft bags.

Derobaz-T DK-2000 is a concentrated bate having a very wide range of applications due to its special formulation. The product is based on bacterial proteases standardized and buffered with special salts and highly effective carriers. Derobaz-T DK-2000 provides increased open-up in fiber structure and cleaner grain surfaces even at low temperatures. By the use of Derobaz-T DK-2000 along with improved area yield, increased tear strength and therefore increased resistance to mechanical operations are obtained.
Even at 20℃ temperature Derobaz-T DK-2000 completely solubilizes the degraded protein forms, and removes the interfibrillary protein and proteoglycans which cover the collagen fibrils. As a result more relaxed but stronger and more elastic leathers are obtained.
