【Properties】

►LEATAN R11 is a clear, readily pourable , water-dilutable liquid. It can be used in   conjunction with all anionic products, e.g., synthetic and vegetable tanning agents as well   as anionic fatliquor agents and auxiliaries.

►Used in the retannage of chrome leathers, the product distinctly improves their fullness   and tightness of grain and reduce their stretchiness.

►Because of its good dispersing effect, LEATAN R11 accelerates the rate of penetration   when it is used in vegetable tannage. The product gives a lighter leather colour and a   pronouncedly fine-pored grain.

►LEATAN R11 is not susceptible to iron salts. When it is used in conjunction with     vegetable tannins, the product can even prevent discolorations caused by iron salts.

【Application】   

In the retannage of chrome leather, LEATAN R11 is used in place of vegetable tannins, if  a pronouncedly full and tight-grained leather is to be produced which is required to possess reduced stretchiness in addition to good light fastness, heat resistance and pale color.  Because of its anionic behavior, LEATAN R11 also lightens the color of chrome leathers that are retanned with the product. If full, dark shades are to be obtained, it is therefore advisable to produce them in a top dyeing process following the retannage.

【Storage conditions】   

Recommended storage temperature:0℃ -40℃
