DEFETCAL SN

BEAMHOUSE AND TANNING AUXILIARIES

Nitrogen free and excellent deliming agent. Its use limits hydrogen sulphide liberation and accelerates the deliming process.

Descriptive properties

Appereance Clear liquid
pH (1:10) App. 7,0
Concentration %98
Storage App. 2 years – dry storage-

Defetcal SN has a very wide range of applications and it does not contain any nitrogen. Its use will decrease COD of the effluent water.

By a rapid and uniform thorough deliming Defetcal SN 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.

When used alone the liberation of hydrogen sulphide is very limited and generally pH will not drop below 8,0 thus Defetcal SN improves the effect of successive bating operations.

Thanks to its degreasing power resulting pelts are much cleaner and dispose exceptionally good dyeing properties

Application recipes
Defetcal SN can be used alone or combined with other deliming agents on split or unsplit pelts. The processing time is dependent upon the type and thickness of pelts and the quality requested.

Alone:
1,5-2,0 % for nitrogen free deliming

When combined with other deliming agents

0,5-1,0 % one should start with Defetcal SN and add other products after 20-30 minutes.

Remarks
We do not recommend deliming above 40℃

Package
250 kg in polypropylene drums.
