Application & Recommendation |

|
|
|
Rockytan RBC 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. Rockytan RBC 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 Rockytan RBC gives a regular and fine pattern. INDICATIONS OF
