New LANXESS products for the wet end process

Levotan LB strengthens LANXESS in its role as one of the leading suppliers of softening polymers for the leather industry, where they are increasingly replacing fatliquoring agents due to their technical and ecological advantages. New, versatile Levotan LB permits the cost-effective production of all the normal articles made from chrome-tanned (wet-blue) or chrome-free (wet-white) leather. ‘Our new Levotan grade makes a distinct difference,’ says Christopher Tysoe, head of the wet-end department in the product development & application section of the Leather Business Unit. ‘It enables manufacturers to reduce the specific weight compared to traditionally fatliquored leather, resulting in end products that are light, fluffy and soft, but nevertheless hard-wearing, exactly what our customers are asking for.’
New Tanigan CF liquid from LANXESS was developed specifically for the manufacture of wet-white leather. It has an excellent grain-tightening effect and good filling properties, and gives a firm, smooth and very flat grain even on soft articles which are dry-drummed for a long time. All this makes the syntan ideal for the production of leather with a smooth finish, but also for embossed goods with excellent print retention. Tanigan CF liquid improves the tightness of loosely structured raw material tremendously, to a level which is not possible with conventional syntans.
The Leather Business Unit is part of LANXESS’s Performance Chemicals segment, which posted sales of EUR 1.93 million in fiscal year 2008.
