JKTAN RE
Synthetic organic resin tanning agent for retanning
chrome leather |
|
Even
small amounts of Jktan RE applied in the retannage will
fill the leather without impairing the fineness and
tightness of grain and the typical chrome leather
character. The product is light fast and allows
production of level dyeings which, however, are somewhat
lightened in shade. Moreover, it improves adhesion of
finishes. |

Properties |
: |
Jktan RE is highly viscous
but readily pourable and simply dilutable with hot
water. Jktan RE is perfectly compatible with synthetic
and vegetable tanning agents, sulphited fatliquors,
anionic dyes and other anionic products.
Even
small amounts will fill the leather without impairing
the fineness of grain and will largely retain the
typical characteristics of chrome leather despite the
use of any vegetable / synthetic retanning agents which
may be additionally required.
Jktan
RE is light fast and gives somewhat bleached, level
shades. Together with white tanning agents, it produces
a still higher degree of whiteness on pale chrome
leathers. Moreover, leathers retanned with Jktan RE can
be readily finished and the adhesion of the finish is
improved in comparison to that on conventionally
retanned leather. |
|
Applications |
: |
Jktan RE is used for
retanning chrome leather to improve its fullness and
tightness of grain without causing formation of a
coarser grain or impairing the other properties of the
leather as is often the result of other filling
retannages with vegetables and synthetic tannins.
Before retannage, the leather must be neutralized
throughout the cross-section. If necessary, exhaustion
of Jktan RE bath can be promoted by adding chrome
tanning agent or a chrome containing synthetic tanning
agent. In this way not only the fullness but also the
softness of the leather is additionally improved. |

Safety |
: |
We
know of no ill effects resulting from the use of Jktan
RE for the purpose for which it is intended and in
accordance with current practice. |
