Benefits and Applications

The Karstedt 20% catalyst is used as a hydrosilylation catalyst. Hydrosilylation describes the reactions to build up high-molecular organosilicon compounds, which serve as the basis for manufacturing silicones. By using the Karstedt 20% catalyst, very low platinum concentrations are contained in the end product. Furthermore, platinum-catalyzed curing is achieved without volatile by-products. The range of catalysts provides options for cure characteristics for every application and can be shipped in various dilutions with polymers to meet customer needs. Heraeus can formulate the activity of the Karstedt’s Catalysts according to the desired catalyst concentration, stability and viscosity. A low turbidity upon mixing with polymers can be expected from the pale, colorless catalyst solution. Heraeus’ catalysts are produced with a narrow variance, which minimizes catalyst waste while delivering constant activity designed for a steady process. The Karstedt 20% catalyst is extremely user-friendly and processable.
