Leather liming and unhairing enzyme
Product description:

Leather liming and unhairing enzyme--alkaline protease enzyme

Product characteristics

  • Finished enzyme used directly
  • Significant reduction in sulfide and liming auxiliaries using
  • Improve leather softness and hand feeling
  • Remove hidden fluff successfully
  • Increase leather skin area, and give leather clear and smooth surface finishing effects.

Instruction

GR-M404 is a bacterial alkaline protease concentrated powder, remove hair on the leather surface during liming process. Compared with no using of this product, It can reduce sulfide and liming auxiliaries using when use GR-M404, which can reduce to 50%. Meanwhile, if no using reduction in sulfide and liming auxiliaries, it can save liming time when using GR-M404.
GR-M404 can replace amine products absolutely, so that can reduce potential dangerous during processing.

Temperature & PH range

When using leather enzyme, product properties are based on technologies, like PH value, temperature, time, natural characteristics of substrate and enzyme activity, and so on. All the factors have influence on product using effects.
GR-M404 function temperature is same as typical liming process, even the enzyme optimum activity effected temperature is 40 degree.
GR-M404 has a wide function PH range, which is 8.0-12.0, and optimum is 10-12.
Due to versatility of enzyme itself, GR-M404 can be used in other leather processes, like liming process.

Usage guidelines

GR-M404 is using directly, which can be used according to specific needs, or mixed using with other auxiliaries as a pre-soak material.
Recommend dosage: GR-M404 0.15%-0.3% (calculate by leather weight)
Leather diversity and different resources, local production operating environment all can affect leather enzyme using effects, recommend to do small testing under same production operating environment, then do mass production.This can avoid damage and influence to hide because of excessive or different process. Particularly to less quality leather, process technology and time must be more accurate.

Technical data (typical)

 Appearance mixture of granules and powder. (Note: color maybe different with each batch, but will not affect product activity and using effects)
 Active ingredients bacterial alkaline protease
 Activity 1000 LVU/g
 Storage 5-25 degree dry room temperature (product should be sealed in occluded devices and avoid exposure to moisture and high humidity)
 Shelf life shelf life is 6 months under correct storage condition. If stored in high temperature or high moisture for long time, should increase dosage to reach desired effects.

Health & safety

All enzymes and preparation products must be stored and used careful specially, avoid direct inhalation and enter eyes. More information, please refer to safety data instruction.

Note

The data is just as guide data, changed based on different production conditions, production technology and effects. Please use the product according to specific requirements, meanwhile, recommend to do small testing, then use in mass production. Suggest to use after testing based on machine types, leather resource, water quality and user requirements. Our company do not response to any loss of leather caused by improper use.
