For applications in high-performance electronics, automotive systems, and industrial machinery, maintaining thermal management and material integrity are essential for success. From the initial pouring or casting to the ongoing management of heat flow, materials must deliver durability, efficiency, and long-term operational reliability.
Evonik is your partner in achieving this. Our portfolio — including delayed action catalysts, high-performance surfactants, specialized dispersing agents, and component compatible thermal management fluids — helps your systems perform in demanding environments.

- Process and Material Control: Catalysts and additives that control cure profile, pot life and demold time in potting, encapsulation and gap-filler systems.
- Tailored Innovation: From electronic potting to heat dissipation systems, our products adapt to your design and production needs.
Solutions by Application Area
Casting Compounds and Elastomers
Achieve precise curing control and robust mechanical properties in your polyurethane systems:
- DABCO® 33 LV and DABCO® T12 – Industry standard amine, metal, and hybrid catalysts that enhance curing behavior and optimize material properties.
- DABCO® and POLYCAT® – Delayed-action amine catalysts that provide controlled, delayed reactivity for tailored curing profiles, supporting consistent mechanical performance in potting formulations.
- ORTEGOL® AP 100 – Adhesion promoter for 2K polyurethane systems, developed to improve adhesion in PU adhesives and potting foams for EV batteries.
Thermal Management
Deliver efficient heat dissipation and long-term safety in electric vehicle battery systems with advanced polyurethane and epoxy solutions:
- POLYCAT® SA – Temperature-activated series of catalysts for customized delayed reaction times and rapid post-curing, enabling optimal heat flow management.
- ORTEGOL® DA Series – Non-ionic dispersing agents for polyurethane thermal interface materials. They reduce the viscosity of highly filled formulations, disperse aluminium oxide and aluminium trihydroxide fillers, and increase maximum filler loading. They do not interact with standard PU catalysts, so cure behaviour is unaffected.
- TEGOSTAB® – Silicone surfactants that stabilize PU froth foam, providing cushioning and thermal insulation for EV batteries.
Immersion Thermal Management Fluids
Ensure your batteries and electrical equipment operate within the ideal temperature range by immersing battery cells in a dielectric fluid. This approach enables efficient heat transfer and enhances durability, enabling safe equipment operations.
VISCOBASE® – Ester-based dielectric fluids for immersion cooling. VISCOBASE® 11-152 has a kinematic viscosity of 4.4 cSt at 40 °C, a flash point of 163 °C (ASTM D92) and electrical conductivity of 0.0001 nS/m at 40 °C, with compatibility confirmed for critical materials including PVC and polyurethane
