Specialty Catalysts – High Sustainability

Organotin catalysts, like Dibutyl Tin Dilaurate (DBTL) and Dioctyl Tin Dilaurate (DOTL), are constantly under regulatory threat and have special labeling requirements when being used around the world. With these challenges, formulators need to be aware and ready with suitable alternatives. At Evonik, sustainability is the central element behind our purpose "Leading Beyond Chemistry" and we are committed to providing innovative solutions that help to make our lives more sustainable, healthier, and more comfortable. To help drive this initiative, we have recently launched a series of bismuth catalysts under the KOSMOS® MB tradename. The KOSMOS® MB series are Bismuth-based catalysts are versatile alternatives to traditional Organotin catalysts. KOSMOS® MB 16 and MB 19 are 16 and 20 wt% bismuth dissolved in neodecanoic acid. And KOSMOS® MB 10 is a specialty developed grade of bismuth that has been optimized for moisture stability to ensure a consistent pot life and cure time during extended storage and application. This technology enables formulators and manufacturers to use ecologically safe polyurethane catalysts and create products and systems that are Tin-, Lead and Mercury-free. Furthermore, they exhibit low volatility with little or no odor. KOSMOS MB® series are ideal for all type of Coating, Adhesives & Sealants and Elastomers polyurethane applications
