Benefits
SELLATAN® RL liq. imparts a uniform filling effect with a soft, round
handle.
With its particularly marked tanning effect, SELLATAN® RL liq. is a
preferred syntan for tanning and retanning metal-free leathers.
It also increases the shrinking temperature considerably and is therefore
very suitable as a tanning/retanning agent after the wet white pretanning.
After milling, leathers tanned/retanned with SELLATAN® RL liq. have an
even milled grain.
SELLATAN® RL liq. is recommended for the manufacture of furskins
(especially white) with higher shrinkage temperature.
Application
In general, 4 - 6 % SELLATAN® RL liq. (calculated on the shaved weight)
is applied in the retanning stage. SELLATAN RL liq. is usually applied in
combination with other retanning agents.
For the tanning of wet white material, 20 - 25 % SELLATAN® RL liq.
(calculated on the shaved weight) is applied in several steps in order to
produce metal-free upholstery or soft type leathers.
