Leather soften enzyme GR-M406
GR-M406 is a safe soften enzyme mainly by trypsin, the product
optimum activity PH is between 7-9.
GR-M406 can mildly open leather fiber structure, clear scurf,
increase leather softness and tear strength, is suitable to produce
very elastic, grain meticulous tight leather.
GR-M406, due to its good cushioning, it it flavor to keep PH value
stable during deliming and soften process.
GR-M406 can used for any type leather soften process. Not only can
use for soft leather soften, but can used for mid-grade soft
leather soften as its properties of safety and uniformity.
GR-M406 increase leather skin acreage, reduce leather thickness,
give leather clean, smooth and uniform process effects.
GR-M406 can directly added to drum to use. The general usage is
join deliming agent, turn 20-60 minutes, then add the product.
Generally, the soften temperature should be controlled within
When at 38C, the soften effect be more strong, and at 32C, soften
process effects to grain will be more mildly and more uniform, but
turn time need longer.
The PH value in soften process should be controlled within 7-9,
optimum PH is 8.0, before using soften enzyme, should choose enzyme
carefully, to ensure can reach a safe, stable and uniform soften
Recommended dosage (weight gray bare skin weigh)
|Leather type||Dosage||Soften time|
|Cowhide furniture leather||1.0 1.5%||60120 minutes|

|Pigskin garment leather||2.0 2.5 %||240360 minutes|
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.
