PUre passion
for electro-casting resins

We are the experts when it comes to thermal management of power electronics.

 
Our unique cooling casting compounds, with thermal conductivities of up to 3.5 W/m*K, ensure optimal thermal management alongside very good processing properties.
 
The result: The operating temperature is reduced, the performance increased and the entire component can be made more compact. Due to the low viscosity and the resulting optimized flow properties, our thermally conductive potting compounds can reach the tightest corners and windings of complex components.
 
This allows for completely new high-tech applications like embedding the windings in electric motors or increasing the performance of modern battery systems and power electronics.
 
But we can do a lot more.
 

Our product portfolio

We cover the entire spectrum of polyurethane-based casting resins. From insulating systems to transparent and flame-retardant potting compounds as well as highly thermally conductive premium potting materials.
