Catalyst TK 14 and TD 18 are organotin compounds for catalyzing single- and two-component condensation-curing systems based on silicones as well as silane terminated polyurethanes (Polymer ST). Application: Catalyst TK 14 is suitable for producing filled and pigmented formulations. Crystalline portions may be formed at room temperature. These can be molten overnight by storage at 30 – 40 °C in a heat chamber. Further processing (metering, pumping) should be done at temperatures above 35 °C. Information provided by Evonik |
