Innovative spectrum of new products for the leather industry
Leverkusen - Bayer Chemicals, a division of Bayer AG, will be presenting chemicals and technologies for the leather industry at Tanning Tech 2003. The focus this year will be on innovative products for the wet end and environment-friendly finishing.
Retingan® R8 is a new, anionic resin tanning material with low astringency and a selective filling effect for the retannage of all types of leather. In addition to improving the grain tightness and surface touch, it also has a good filling effect, especially in the loosely structured parts of the hide. Retingan® R8 gives leathers with a clear, pale color and good buffing and embossing properties.
Cismollan® UAL is a new liming auxiliary based on aliphatic amines for use in the
beam house. This environment-friendly product can partly replace products normally used such as sodium sulfide and sodium hydrosulfide. It helps to open up the collagen fibers, giving full leathers with a round handle. Cismollan® UAL also preserves the substance in the belly and flank areas, thereby ensuring a more uniform hide Substance over the entire hide or skin and preventing loose grain. Because of its buffering effect and the improved solubility of the lime, Cismollan® UAL can also be used in the
reliming.
Tanigan® PAK is a new, lightfast retanning material with a pronounced neutralizing and buffering effect. As the product is anionic, it is bound by chrome leather and other mineral-tanned leathers. Leathers retanned with Tanigan® PAK have a smooth grain and level, full
dyeings.
 Tanigan® LT-N liquid is a new, phenolic replacement tanning material for the retannage of chrome leather and the tannage of all types of raw material. Chrome leathers retanned with this product are very full and soft and have a pale color. It can be combined with all the conventional products used in the retannage such as neutralizing, resin, vegetable and polymer retanning materials. When used in vegetable tannage, Tanigan® LT-N liquid gives supple leathers with a pale color and a very fine grain.
Tanigan® LTS is a new, low-astringency, synthetic tanning material on a phenolic basis which is used primarily in the pretannage of vegetable leather, but can also be used for retanning chrome leather. When used as a
pre-tanning material, it accelerates the penetration of the vegetable extract and gives leather with a uniform, pale color and a fine, soft grain. In the retannage of chrome leather, Tanigan® LTS can be combined with all the common retanning materials such as neutralizing agents and resin and polymer tanning materials. Chrome leather retanned with Tanigan® LTS is soft and has good fullness and a pale, uniform color.
