Innovative beamhouse technologies
LANXESS offers a novel, environment-friendly processing technology which reduces usage of water, chrome tanning agents, time, manpower and eliminates use of sulphuric acid, common salt and basification process.
PELTEC C-based process combines deliming, pickling, tanning steps and reduces TDS in the discharged waste water significantly. Blancorol HP EXP 4122 is a special auxiliary for the chrome tannage with well-balanced ingredients that have an effect of non-swelling acids. The product allows to reduce the amount of salt used in the pickle and improves the penetration of the subsequently applied chrome tanning material. It supports the production of lightweight articles which is a desired character of modern leather.
Tanigan UW is an arylsulfonic acid and hydroxyarylsulfone condensation syntan for application on wet blue and wet white. It is a retanning syntan for all types of leather and especially for white and light-coloured leathers with good fastness properties.
Waterproof with Levotan W
Levotan W is a patented, functionalised silicone containing microemulsion. It can be used with Levotan WRP to manufacture all types of leather requiring waterproofing especially upper leather, for example, hiking boots and golf shoes but with high water vapour permeability, which translates into greater wearer comfort. Leather made with this product displays a fine tight grain, lightweight and a natural feel. Levotan W also yields high and reproducible results in Bally and Maeser dynamic tests as well as static water absorption. It offers high stability and avoids the risk of premature precipitation due to low pH, hard water or other electrolytes present in retanning, eliminating the risk of staining.
The system gives excellent dyeing properties, including a high level of colour uniformity across different batches and all kinds of hides and skins. The dyeing between flesh and grain is tone-in-tone, making it ideal for all types of waterproof leather, including nubuck.
Levotan WRP for medium to firm leather
Levotan WRP offers excellent product stability and is indispensable for medium to firm leather. It is even suitable for military application articles with a tight grain. Even with relatively high application rates, the leather does not soften significantly. Levotan WRP has very good penetration and distribution. Furthermore, an excellent, uniform dyeability is achieved. The treated leathers are characterised by a high filling, fastness and resistance to migration.
Upgrading technology for shoe, leather goods and garments
LANXESS offers products and know-how to upgrade lower grade raw materials to high quality elegant leathers. For instance, EUDERM Prebottom NB EXP 2244 is a non-ionic, aqueous prebottom for upgrading shoe upper and leather goods articles. This is burnishable and can be used for aniline like articles with good natural touch. Baysin X-TRA Luster HT-C EXP 2248 is a hard protein luster that can be used in aqueous base and top coat formulation. Applied in resin base coats, it reduces tackiness of the finish and enhances the dry fastness properties. Baysin X-TRA Luster HT-C EXP 2248 imparts a natural glossy appearance and a pleasant, dry surface touch to the finishes.
