Regulatory restrictions on the use of tin catalysts create considerable difficulties for formulators of crosslinkable silane terminated polymer systems. A tin-free organometallic catalyst can give good mechanical properties with similar cure times, and even cure one system where tin compounds are ineffective.

 

John Florio, Ravi Ravichandran, David Switala and Bing Hsieh from King Industries discuss the organometallic catalysts developed for moisture cure silane-terminated polymer systems in the article titled Non-Tin Catalysts for Alkoxy Silane Polymers, published in the European Coatings Journal, issue 3/2016.
