EPIZOTAN FBC has a wide field of application both as a tanning agent for white leathers and as a bleaching agent for chrome and vegetable tanned leathers.

EPIZOTAN FBC gives good results in the retannage of chrome tanned leathers, which will retain a very fine grain and a soft feel. Due to its excellent light fastness it is particularly suitable for the production of white leathers.

In the retannage of leathers to be dry milled EPIZOTAN FBC gives a regular and fine pattern.
