Model NO.: GR-M401 Certification: SGS Classification: Leather Auxiliary Agents Appearance: Powder Transport Package: 25kg/Paper Drum Origin: Cn Environmental Protection: Yes Color: White Function: Leather Soften Trademark: Green Specification: standard HS Code: 350790 acidic protease leather
Soften Enzyme Product properties ² Direct using acidic protease finished enzyme ² Rich product--used in many acidic tanning operations ² Promote the absorption of tanning auxiliaries ² 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 25-38ºC ) , even the enzyme optimum activity effected temperature is 40-50ºC. 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, 90-120 minutes 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. Technical data (typical) Appearance: powder (Note: color maybe different with each batch, but will not affect product activity and using effects) Active ingredient: acidic protease Enzyme activity: 2000LVU/g PH Value: about 3.5-6.5 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 12 months under correct storage condition. If stored in high temperature or high moisture for long time, should increase dosage to reach desired effects. Health and safety All enzymes and preparation products must be stored and used careful specially. More information, please refer to safety data instruction. Technical support There is strong technical service system in our company team, can provide necessary usage directing agent complex guidance, meanwhile, recommend to use different enzymes against different leather, provide full range of high quality product improvement and aftermarket service in time.
