Chemical & Physical Data:
alkali protease with synergistic liming agent
1.Improve the opening up of collagen fibre bundles, ring protein and polysaccharide to give softer and fuller leather.
2.Remove the scuds and natural pigmentation to give a clean & brighter grain surface.
3.Remove hair roots and reduce the growth marks.
4.Shorten the liming time, reduce the dosage of sodium sulphide, and lime requirement.
5.Improve the flatness, fineness of the grain surface & tear strength.
6.Promote uniformity of lime distribution and penetration because of the increase solubility & suspending stability of lime thus produce cleaner waste water discharge from the process.
7.Poorly cured or putrefied hides should be carefully treated with appropriate percentage of DOWELLZYM LM.
DOWELLZYM LM is mainly used in liming, reliming and paint liming of cattle hides, pig skin, goat skin and sheep skin with high fats content.
DOWELLZYM LM can be added directly to the liming float without dissolving. After the addition drum should be run at least for 30 minutes in order to distribute enzyme more evenly.
For paint liming, DOWELLZYM LM should be mixed very well in lime solution and then add the balance quantity of lime to the required level of viscosity in lime painting mixture. The liming paint solution with LM should be used over as soon as possible.
Application example(based on the weight of wet-salted skin):
Raw hides and skins The dosage of DOWELLZYM LM
Cattle shoe upper0.2%-0.35%
Pig skin garment0.5%-1.0%
Goat skin garment0.5%-1.0%
Sheep skin garment0.1%-0.5%
Avoid breathing dust and contact with skin，excessive contact may cause anaphylactic reaction. If splashed into eyes，immediately wash with plenty of water.
