      abstract     = {Silicon sensor based particle detectors operated in a
                      hadronic radiation environment need to be cooled to
                      counteract the radiation induced leakage current and to
                      prevent thermal runaway. To achieve this most efficiently, a
                      low thermal resistance is required between the detector
                      modules and the cooling structures. In many cases dry
                      thermal contacts are sufficient, but especially for a
                      large-area contact so-called thermal interface materials
                      (TIM), largely availably on the market in many forms, are
                      the preferred choice. However, in the use case for detector
                      cooling there can be many requirements, such as non-liquid
                      phase, no heat cure, low thermal impedance, no compression
                      force, radiation hardness, making it challenging to find a
                      suitable TIM. One option are room temperature curing two
                      component thermal gap fillers.The thermal test setup
                      determines the thermal conductivity of a test sample by
                      measuring the temperature gradient with a controlled amount
                      of heat flow through a sample.Mechanical tests are required
                      to qualify the structural integrity of the thermal interface
                      under thermal stress and mechanical stress.Resembling the
                      style of an ISO 4587 lap shear test, and an ISO 25217 mode-1
                      fracture test, test samples were prepared with a large 5 ×
                      5 cm2 adhesion overlap using plasma cleaned carbon fibre
                      plates to have a surface comparable to its intended use
                      case.After testing of unirradiated samples, they have been
                      irradiated to 600 kGy. The measured mechanical and thermal
                      properties are presented and the results before and after
                      irradiation are compared.},
