Solution based on aluminium salts.
CORETAN TAL is a mineral tanning agent based on aluminium.
Like all mineral tanning products, the compatibility of CORETAN TAL with fatliquors, others retanning agents and auxiliaries must be checked before using.
CORETAN TAL is compatible with chrome tanning agents and with the majority of non ionic and cationic products.
The use of CORETAN TAL in tanning or retanning gives to the leather a fine and firm grain, if used on suede we obtain a leather very compact, with a brilliant dying and a very good writing effect.
CORETAN TAL is especially indicated for the post-treatment (esterification) of waterproofing pastel shade or white leather.
Percentages of use vary from 2% to 10% depending on the kind of article and of wished effect.
