Acidic leather enzyme
Product description:

Leather soften enzyme---acidic protease GR-M401

Product properties

  • Direct using acidic protease finished enzyme
  • Rich product--used in many acidic tanning operations
  • Promote the absorption of tanning auxiliaries
  • Remove redundant scrimp, improve softness and increase skin acreage.        

Instruction

Acidic protease GR-M401 is an acidic proteolytic enzyme, can used as a leather soften auxiliary. Used in poor quality leather, promote smoothness and increase skin acreage. It can be used in acidic process, such as acid pickling, dual-face and wet blue reforming process.

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.

Acidic soften enzyme GR-M401 function temperature is same as typical soften process (about 25-38℃), even the enzyme optimum activity effected temperature is 40-50℃. Acidic soften enzyme has a wide effected PH range, which is 3.5-6.5, the optimum is 4.5.

Due to versatility of enzyme itself, acidic soften enzyme can be used in other leather processes, such as, wet blue reforming process. It can improve quality of wet-blue leather, improve leather softness.

Usage guidance

Acidic soften enzyme GR-M401 is a finished enzyme which can be used directly. Can be added based on requirements, or mixed using with other auxiliaries as a soften material.

Recommended dosage: 0.5%-1.5% (calculate by leather weight), the technology is: in peeled or deacidification, add in the remaining 60-90 minutes; in alkalization process, 90-120minutes before using retanning agent, use the products; or use in advance in the neutralization process.

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.
