Synthetic replacement tanning agents

Jktan OS is a versatile synthetic replacement tanning agent for the retannage of chrome leather and for vegetable tannage.



Phenol-Napthalene condensation product
Specification : Concentration          96% approx.
pH (5 gms/lt)           3.8-4
Tannin Content        80% approx.
Appearance : Jktan OS is a spray dried, pale cream-coloured powder, readily soluble in cold and warm water.
Properties : Jktan OS imparts a high degree of suppleness and in addition, it improves the tightness of the grain.  It has a strong bleaching effect when used in its own on chrome leathers.  The good dispersing effect of Jktan OS results in a deeper and more uniform penetration of the other retanning agents.  It has a slight buffering action.  Jktan OS has a medium strong filling effect.  Jktan OS is equally suitable for use in conventional vegetable tanning systems.  It prevents sludge formation in vegetable tan liquor and makes the colour of the leather much brighter, lighter and cleaner.
Application : Jktan OS is suitable for a wide range of applications in the production of
a) full chrome and retan upper leathers
b) aniline and pastel coloured shades
c) suede clothing leathers
d) vegetable tanning
e) clothing nappa
Safety : We know of no ill effects resulting from the use of Jktan OS for the purpose for which they are intended and in accordance with the current practice.
