  DENIE-B LPS-P
                                              Metallo-protease for Leather Rebating

BENEFITS:

                          *  Easy to formulate into a ready to use product.
                          *  Enhances the performance of protease rebating products.
                          *  Reduces wrinkles, improves softness and increases surface area.
                          *  Improves uptake of tanning agents.


INTRODUCTION

DENIE-B LPS-P is an metallo-protease enzyme concentrate designed to be diluted prior to being used as an enzymatic rebating agent. On poorly bated pelts it reduces wrinkles and increases area yield. Its performance can be enhanced by the use of alpha-amylase enzyme (available from DENYKEM Limited)

Dilution may be undertaken by the tannery or, more commonly, by third party formulators who may blend it with other active constituents.


TEMPERATURE and pH PROFILES

The performance of enzymatic leather processing products depends upon process conditions such as temperature, pH, time, nature of the substrate and enzyme concentration.

The nature of DENIE-B LPS-P means that it is effective in the temperature range used in the rebating process. Its optimum temperature for activity is approximately 40° - 50°C.

DENIE-B LPS-P is effective over a wide pH range with optimum activity at pH 6.5 – 7.5.


DIRECTIONS FOR USE

DENIE-B LPS-P has a high enzyme activity level and should not be used directly in leather processing stages in its neat form. The product should be diluted or used as a constituent of a rebating preparation prior to use. The dosage level of a dilution or preparation should be equivalent to using DENIE-B LPS-P at 0.00025% – 0.00050% on weight of hide. The preparation should be added at pH 5.5 – 6.0 during neutralisation and 60 - 120 minutes before the start of retannage.

Variations in hide and local conditions can affect the performance of leather processing chemicals. DENYKEM recommend that small scale tests are carried out under local conditions before using products in full scale production. This will avoid any overdosing and any damage that may result from it. This is especially important where poor quality or badly preserved hides are being processed.
