Australia DENIE-BATE PVP-P Leather Bating Protease

Specifications

BENEFITS                        * Easy to formulate into a ready to use product.

                                          * Increases the surface area and reduces the thickness of the hide.

                                          * Increases softness and tear strength.

                                          * Gives a clean, pale and even finish. 

INTRODUCTION 

DENIE-BATE PVP-P is a protease enzyme concentrate designed to be diluted prior to being used as an enzymatic bating agent. Maximum performance is achieved when used in conjunction with amylase and lipase enzymes. These are also 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, and time, nature of the substrate and enzyme concentration.

The nature of DENIE-BATE PVP-P means that it is effective at typical bating temperature (approx. 35° - 38°C) even though its optimum temperature for activity is approximately 40° - 45°C.

DENIE-BATE PVP-P is effective over a wide pH range (6.0 – 10.0) with optimum activity about pH 8.0.

Due to the type of enzyme and its versatility, DENIE-BATE PVP-P can be considered as the enzyme constituent of products used in other leather processing stages such as soaking.

DIRECTIONS FOR USE 

DENIE-BATE PVP-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 bating preparation prior to use. The dosage level of a dilution or preparation should be equivalent to using DENIE-BATE PVP-P at:

          Bovine hides; Lamb and Sheep pelts  0.004% – 0.006% on weight of hide.

          Goat pelts                                             0.003% – 0.004% on weight of hide.

          Pigskin pelts                                         0.007% – 0.010% on weight of hide.

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.

TECHNICAL DATA (typical) 

Appearance:            Pale powder.  (Note: Colour may vary. It is not an indication of product strength.)

Active constituent:  Pancreatic protease.

Activity:                     280,000 LVU/g

Storage:                  Storage temperature should be controlled between 5° and 25°C. Keep in sealed containers and                                  avoid exposure to moisture and high humidity.

                                 If there is an extended storage period, higher temperature or high moisture levels, dosage                                  requirements may need to be increased.

HEALTH and SAFETY

As with all enzyme products special care needs to be taken to control exposure. Please see the safety data sheet.
