Cationic maleic anhydride multicomponent copolymers and their complexes
It is suitable for the retanning of all kinds of chrome leather. It can produce uniform density leather, reduce the position difference of the leather, make the grain of the leather compact, soft and plump handle, good light resistance, and dyeing without discoloration. When the pH is lower than (45 65 Because of its insensitivity to high temperature (below 50 C), after fatliquoring, good filling can be achieved, which is conducive to adjusting the balance of charge on the surface of leather fiber, and can help to absorb late materials.
