ADHESIVE BONDING
Adhesive bonding is the oldest joining technology used and at the same time a very modern technique with a strongly increasing number of applications. Today it is an indispensable alternative and supplement to other joining processes in industrial production.
We find suitable adhesives for the requirements of our customers and enable their successful application in their processes. We also provide our measuring technology for the ageing prediction of bonded joints and interpret damage patterns. Within the scope of industrial contract research we develop solutions for the special bonding ideas of our customers. With our expertise from publicly funded research projects, we can find optimal solutions for our customers and partners to make adhesive applications conform to standards.

Measurement possibilities
Our plant technology at ifw Jena enables us to determine the properties, potential and limits of various adhesive solutions using a wide range of measurement options. These include:
- Determination of rheological properties (shear rate, shear stress, viscosity, deformation, complex viscosity, real and imaginary part of viscosity, loss factor, shear modulus, storage modulus, loss modulus, volume shrinkage, glass transition range)
- Investigation of the curing of adhesives under UV light and in the temperature range from -40 °C to 180 °C
- Determination of thermal expansion in the temperature range from -180 °C to 1,600 °C
- Determination of thermal resistance in the temperature range -120 °C to 1,600 °C
- Determination of tensile shear strength according to DIN EN ISO 527
- Determination of compressive shear strength according to DIN EN ISO 13445
- Determination of strength under dynamic load in the temperature range -70 °C to 350 °C
- Determination of the mass increase after storage in different media with determination of the mass loss according to DIN EN ISO 62
- Gas leak test
- Evaluation of surface characteristics
