Application recipes
Defetcal DK-29 NEW can be used alone or combined with other deliming agents on split or unsplit pelts. It may be added to the drum either diluted or in powder form. The processing time is dependent upon the type and thickness of pelts and the quality requested. We recommend Defetcal Dk-29 NEW addition prior to any ammonium sulphate addition if the later is being used.
Standardization procedure for wet blues of different sources or parties:
| Washing | % 200 40°C | Water | |
| + % 1,0 | Defetcal DK-29 NEW | ||
| + % 0,2 | Formic acid -> | 60’ Run Drain | |
| Washing | % 200 40°C | Water | 10’ Run Drain |
| Retanning |
% 200 40°C | Water | |
| % 1,0 | Emdirenal DK-11 NEW | 10’ | |
| + % 4,0 | Tankrom AB (Kromsan) | 40’ | |
| + % 0,5 | Sodium Formate | 30’ O/N pH 3,8 – 4,0 | |
| Drain. |
Remarks
We do not recommend deliming above 40℃.
Packaging
25 kg in kraft bags.[/vc_column_text][vc_column_text]Defetcal DK-29 New has a very wide range of applications. As a deliming agent it accelerates the deliming process and improves grain strength, as a pickling acid it enhances the chrome uptake.
In deliming, by a rapid and uniform thorough deliming Defetcal DK-29 New removes lime blasts and chemically bound lime without causing any damage to the grain. Smooth and finely grained pelts with very good dyeing properties are obtained.
By its addition to the pickling bath Defetcal DK-29 New gives appreciably fuller and mellow handle leather. Thanks to very good chrome fixation less chromium salt is removed during the rinsing and retanning of the shaved leathers. Due to its special features a standardization procedure* is being set out to overcome uneven dyeing of different origin wet blues.[/vc_column_text][vc_column_text]
