Appearance:     Brown powder

pH (1%):          5.0~8.0

Properties:

lDOWELLZYM FE is used in acid conditions for bating fur leathers, and its optimum pH value is 3.0-5.0.

lDOWELLZYM FE has high acid activity, and its dosage can be appropriately optimized.

lDOWELLZYM FE gently loosen the skin structure, make fur more softer and fuller with better elasticity thus promote the absorption of tanning materials and make dyeing more even.
