Description: Das Projekt "Neue Vernetzungsmittel mit geringer Umweltwirkung fuer den Einsatz in der Lederzurichtungstechnik" wird vom Umweltbundesamt gefördert und von Bayer AG durchgeführt. General Information: The aim of this project is to single out a new cross-linker with low environmental impact to be used as cross-linking agent in a number of leather finishings. Currently, among the most frequently used products are aziridine derivatives, which are noxious, and which present many problems in handling, stocking and for the health and safety (H&S) of the leather workers. Moreover, aziridine monomer, a mutagenic and cancerogenic substance, is still contained in the commercial product as an impurity. The use of aziridines as cross-linkers is due to their ability to improve some properties of the finish, such as resistance to scratch, adhesion, chemical resistance, and durability. The sheer quantity of aziridine derivatives used as cross-linkers in a single tannery is quite modest if compared with the quantity of other chemicals used both in the tanning and in the finishing of leather, but aziridine derivatives are used in most tanneries that carry out the finishing of leather. We can estimate that the quantity of aziridine derivatives used every year in Italian tanneries is in the range of 60 to ns. The tanning sector is not alone in making use of aziridines, as these latte r are used as cross-linkers for coatings also in the textile and the wood finishing sectors. Nevertheless, the tanning industry is undoubtedly one of the sect ors in which the replacement of noxious and toxic substances by safer ones is a priority. The objectives of this research are: (1) the substantial reduction of the health and safety potential problems of the workers; (2) the improvement of the quality of the workplace; (3) the reduction in the production and trade of hazardous substances; (4) the early compliance with more severe legislation for hazardous substances that is likely to be issued in the near future; (5) the development of a cross-linker that can be adapted to different types of leather; (6) the possible improvement of the quality of leather; (7) the technological improvement of the leather finishing sector, accomplished through the improvement of chemical and environmental knowledge of finishing; (8) the improvement of the relations with public authorities and unions. It is important to point out that the aim of the project goes far beyond the mere compliance with H&S regulations, as it tries to provide to SMEs the possibility of adopting a policy of improvement of the health at the workplace through the adoption of prevention measures like the replacement of toxic substances by less toxic ones. The research will focus on a preventive screening of existing cross-linkers and it will be aimed at focusing the problem of time of reticulation of the products and especially their flexibility and strength characteristics. On the basis of these tests, either the most suitable existing cross-linker will be adopted, or an evolution ... Prime Contractor: Conceria Beschin Gino SpA; Arzignano; Italy.
