Limeqin MF

Limeqin MF is an auxiliary product for unhairing procedure, free of amines and can be used both for unhairing with total lost of hair and for unhairing with hair recovery. It attacks the prekeratin proteins of the hair, which produces a better extraction both of the hair root and of the belly grain. It reduces the fibre structure tautness, so that the leather will be less swollen and it also permits a better penetration of the rest of the unhairing products.

Limeqin MFO

Useful both for unhairing with hair recovery and for hair destruction. It works on the pre-keratinous proteins by eliminating greasy residuum and rests of hairs, leaving behind a relaxed and smooth fibre. By using this product the swelling caused by the alkali is decreased. It also provides better crossing of the lime and the sulphide through the leather. This improves the penetration regarding the regularity of the products added later.
