Specialty chemicals manufacturer TFL has launched Sellatan Ll-G Liq, a highly masked pre-tanning agent with a low impact on health, safety and the environment. In response to the demand for chromium-free technology, the Germany headquartered chemical supplier has launched Sellatan LI-G Liq, with an optimised GA content, aimed at automotive leathers as well as footwear and leather goods. TFL says it has developed the product "with the recent changes to the classification for Glutaraldehyde (GA) in several Asian countries and the EU in mind". This non-ionic pre-tanning agent features a low vapour pressure to substantially reduce the typical aldehyde smell during application, hence, helping to improve workplace health and safety, according to the manufacturer, which claims the highly masked Sellatan LI-G Liq also features an excellent penetration and distribution throughout the cross-section; even on full substance pelts. "It is highly efficient as almost all GA applied is exhausted from the bath. In addition, it reduces the drying out of the wet-white and provides a good wetting back behaviour", says TFL.
