MAC R is a classic bating agent for precious skins like calves and kids where it cleans the grain well, making it fine and elastic.

MAC R, if used in low percentages, is used in the working of skins which must retain a certain consistency, but if used in higher dosage it is employed with soft skins like tssel and softy.

Anyway, the MAC R action is powerful, and the working times have to be followed carefully and they must never be too long.
