Chromium Complex of Stearic Acid as a Durable Water-Repellent for Leather

Article Preview

Abstract:

This work relates initially to the application of various chemical formulations on leather surfaces to function as water repellents. Efforts have been made to search for a nonfluorinated formulation because of the damaging health effects of fluorinated water repellents. The metal complex stearato chromic chloride, which was prepared in the laboratory, is the most suitable. A complete synthesis protocol is developed first. Characterization tests (ATR-FTIR, XRD) of the chemical were performed to confirm that the intended product was properly synthesized. Microscopic examination of the leather revealed that it was not damaged by the application of the formulation and retained its softness and ability to feel. The methods of application to leather are then described. Finally, the necessary tests of performance are completed. For the different types of leathers that are evaluated, stearato chromic chloride can be easily applied and used as a compatible, durable and permanent water repellent. When synthesized according to a given protocol, minimal repellent chemicals are present in the exhaust solution, thus safeguarding the environment against chromium toxicity.
