TRUPOCAL AF

ammonium salt-free deliming agent

Appearance:

beige powder.

pH value (1 : 10):

approx. 4.5.

Properties

TRUPOCAL AF is an ammonium salt-free deliming agent.

TRUPOCAL AF has optimum buffering properties and guarantees a gentle course of deliming without any sudden decrease in pH-values.

TRUPOCAL AF produces also an even deliming for unsplit limed hides.

TRUPOCAL AF results in  a very fine and clean grain pattern.

TRUPOCAL AF is readily water-soluble and best suited for low-float processes (‚dry deliming‘).

In the production of chrome-free leathers the shrinkage temperature is raised by 5°C when using TRUPOCAL AF in the deliming process. The pre-tanned hide material appears lighter in colour.

Application

TRUPOCAL AF is added undissolved in 2 - 3 portions into a float of 20 - 50 %.The dosage depends on the type of limed stock and the desired degree of deliming. For total ammonium-free deliming a dosage of 2 - 4 % TRUPOCAL AF (based on pelt weight) is necessary.

Safety and storage

It is recommended to wear a protective face mask when weighing.
The product should be kept in a dry place.
