DYHARD® for adhesives

The crucial requirement for adhesive components is to have a long shelf life even at higher temperatures. This means that the accelerators used in the mixture with epoxy resins, hardeners and fillers must have a very special reactivity profile such as high latency at room temperature and enough reactivity at elevated temperatures.

As adhesives are applied in thin layers, they require stable hardeners with a low particle sizes. DYHARD® hardeners are micronized to a particle size of d98 ≤ 6µm.

The resulting “reactive hot melts”, or single component adhesives, are used as structural adhesives, particularly in the automotive industry, in which they replace conventional technologies such as riveting and welding.
