Technology & Requirements

Adhesive technologies distribute stress evenly, minimizing cracks, deformation, and material fatigue. This is particularly important for liquid coolers and cooling plates.

Bonding allows the joining of materials with different coefficients of thermal expansion, such as aluminum and copper, and compensates for these differences flexibly. The technology is therefore ideal for high-performance applications in power electronics, automotive, and industrial electronics. Sensitive electronic components or sensors can also be integrated, as adhesives cure without high temperatures. This prevents metallurgical changes and protects the components.

Thermal Efficiency & Heat Conductivity

Large and complex surfaces can be bonded uniformly, improving heat transfer between components. Specially developed thermally conductive adhesives optimize the thermal flow and increase heat dissipation efficiency – crucial for high-performance applications such as LED heat sinks, inverters, or power electronic modules.

Benefits & Automation

  • Excellent sealing function: Prevents penetration of liquids or contaminants

  • Easy automation: Uniform, reproducible application

  • High design flexibility: Complex, delicate structures without mechanical fastening

  • Thermal and mechanical integrity preserved: No deformation or melting

  • Environmentally friendly: Low temperatures, no harmful emissions

  • Efficient & cost-effective: Especially for series production
