One-Part Acrylates/Methacrylates

With one-part acrylate/methacrylate adhesives, the reaction is initiated by peroxides, as in the case of two-part systems. Since, with one-part adhesives, the peroxides do not decompose under the influence of the hardener but rather under the effect of temperature, the storage stability and desired reaction time must be aligned with each other. In order to allow storage and transportation under normal conditions, the adhesives have curing temperatures from 120 ° C upwards. The reaction temperature is determined by the half-life of the peroxides (Table 5.5).

The lower the desired reaction temperature, the less storage-stable the adhesive.
