Monobutyltin hydroxychlorideButyltin hydroxychloride
This organotin catalyst is used in the synthesis of saturated polyester resins for powder coatings. In the production of unsaturated polyester resins, it is used for end applications in gel coatings, sheet molding compounds and in casting processes.
Another field of application is the production of PBT engineering resins for the automotive and construction industries. In economic terms, PBT resins are the second most important polyester worldwide.
In addition to the synthesis of binders and alkyd resins, use also includes antioxidants for which the catalyst is used in transesterification reactions at temperatures between 140 and 180 °C.
