Application：

T12 is mainly used in 1K-CASE applications and less reactive than T 9.In combination with amine catalysts synergetic effects can be observed.

In some cases oxidative degradation may take place caused by tin catalysts like T12 .To avoid degradation problems we recommend the use of DMDEE instead of tin catalysts for 1K applications.
