Efficient free radical remover and reducing agent
The hexavalent chromium in the leather is eliminated by the mechanism of reduction, and the oxidized radical existing between the leather fibers has a capturing function, which effectively inhibits the formation of hexavalent chromium. It can effectively reduce the content of hexavalent chromium in chrome tanning crust leather, and prevent the production of hexavalent chromium in the subsequent processing of chrome tanning crust leather, which helps the leather to maintain good ecological properties.
Active substance (%) ≥ 95
(1) In the neutralization process of the crust leather and the dyeing and fatliquoring fixation, 2.0% can be directly added.
(2) In the dry state finishing process, it is configured as a 20%-25% aqueous solution, and sprayed directly on the meat surface of the finished leather in a mist form, the spray amount is 150~200g/m2, and then it is hung and dried.
