Low viscosity, high performance
Desmodur® low unreacted TDI prepolymers for hot cast polyurethane
Desmodur® low unreacted TDI prepolymers from Covestro allow for easier and safer processing with improved dynamical properties.
Desmodur® low unreacted TDI-based systems provide high resilience and load bearing ability. The more ordered structure of Desmodur® low unreacted TDI-based prepolymers allows the formation of polyurethane cast elastomers with morphologies that provide higher performance, particularly in extreme environments.
Compared with conventional TDI prepolymers, Desmodur® low unreacted TDI prepolymers benefit from:
- Low free TDI content
- Low viscosity
- Long pot life
- Outstanding dynamical properties
From a health and safety point of view, our Desmodur® low unreacted TDI prepolymers further protect operators with free monomer content less than 0.1%. These products further reduce worker exposure, limiting health and safety issues.
The processing assets of low viscosity and long pot life allow an easy final elastomers process.
