Paske nan kowòdone kapasite nan sèl kwomik ak carboxyl nan kolagen an, sèl kwomik ka fòme kowòdone kosyon ansanm ak fib kolagen an pou amelyore estabilite pwodui chimik rezistan ak estabilite mekanik nan natirèl materyèl polymère segondè, retire enpurte tankou bèt grès sou pelt epi fè trete a kwi douser ak cleaner.

Because of coordinating ability of chromic salt with carboxyl of collagen, chromic salt can form coordinate bond together with collagen fiber so as to enhance chemical resistant stability and mechanical stability of natural high polymer material, remove such impurities as animal fat on pelt and make the treated leather softer and cleaner.
