Rockenzyme 7500-L – Alkaline Protease Bating Agent for Superior Leather Quality

High-Performance Enzymatic Bating Agent for All Types of Leather

 

Rockenzyme 7500-L is a premium alkaline protease bating agent specially developed for the beamhouse operations of the leather industry. Formulated with proteolytic enzymes, ammonium salts, and buffering agents, it efficiently removes unwanted proteins from hides and skins while improving grain quality, softness, and smoothness.

Suitable for all types of pelts, Rockenzyme 7500-L delivers controlled enzymatic action, resulting in cleaner grain, enhanced leather feel, and excellent preparation for subsequent tanning and finishing processes.

 

 

What Is Rockenzyme 7500-L?

Bating is an essential step in leather manufacturing that follows deliming and prepares the hide structure for tanning. Rockenzyme 7500-L contains highly active alkaline protease enzymes that selectively break down and remove non-structural proteins, residues, and impurities without damaging the collagen fibers.

Its balanced formulation provides effective bating performance while maintaining process stability and leather quality.

 

 

Key Benefits of Rockenzyme 7500-L:

  • High-performance alkaline protease enzyme system.
  • Suitable for bovine, sheep, goat, and buffalo pelts.
  • Improves grain clarity and smoothness.
  • Removes excess proteins and non-fibrous substances.
  • Produces softer and cleaner leather.
  • Enhances leather handle and touch.
  • Promotes better penetration of tanning chemicals.
  • Helps achieve more uniform leather quality.
  • Contains ammonium salts and buffers for stable performance.
  • Compatible with conventional leather processing systems.

 

 

How Rockenzyme 7500-L Works

 

Rockenzyme 7500-L acts during the bating stage by selectively hydrolyzing and removing unwanted proteins remaining after liming and deliming.

Its enzymatic action helps to:

 

  • Clean the leather grain.
  • Improve fiber opening.
  • Remove residual proteins.
  • Enhance softness and flexibility.
  • Produce smoother and finer leather surfaces.
  • Prepare the pelt for tanning and finishing operations.

 

The result is a cleaner and more uniform leather structure with improved physical and aesthetic properties.

Typical Process Guideline

After liming, fleshing, and deliming:

 

  • Add 100% water at 37°C.
  • Add 0.1% Rockol 642.
  • Add the required amount of Rockenzyme 7500-L.
  • Run for 30–60 minutes.
  • Check the degree of bating and drain.
  • Wash with 300% water at 25°C for 15 minutes and drain.
  • Wash with 300% water at 20°C for 15 minutes and drain.

 

Process conditions may vary according to leather type and production requirements.

 

 

Performance Advantages in Leather Processing

Pelts treated with Rockenzyme 7500-L exhibit:

 

  • Cleaner grain and improved grain definition.
  • Enhanced softness and flexibility.
  • Better smoothness and touch.
  • Uniform fiber opening.
  • Improved penetration of tanning chemicals.
  • Higher-quality finished leather.

 

Its balanced enzymatic action ensures excellent results without excessive attack on the collagen structure.

 

 

Storage Conditions

Store Rockenzyme 7500-L in tightly sealed containers between 5°C and 25°C.

For optimum performance:

 

  • Keep away from direct sunlight.
