Summary:

Anaerobic adhesives (AAs) cure at room temperature in oxygen-deprived spaces between metal substrates. The curing process is significantly influenced by the type of metal ions present. This study investigates the curing kinetics of a high-strength AA on iron and copper substrates using differential scanning calorimetry (DSC). The activation energy and kinetic parameters were determined with different empiric models, revealing that curing on copper is faster and more complete compared to iron. The findings suggest that copper ions lower the activation energy required for curing, enhancing the adhesive’s performance. This research addresses the gap in understanding how metal ions affect AA curing kinetics, offering valuable insights for optimizing adhesive formulations for industrial applications.

Spanish layman's summary:

Los adhesivos anaeróbicos curan a temperatura ambiente en espacios sin oxígeno entre sustratos metálicos. El proceso de curado depende en gran medida de los iones metálicos presentes. En este estudio, se ha observado que los iones de cobre aceleran y completan mejor el curado en comparación con los de hierro, reduciendo la energía de activación necesaria y mejorando el rendimiento del adhesivo.

English layman's summary:

Anaerobic adhesives cure at room temperature in oxygen-deprived spaces between metal substrates, with the curing process influenced by the type of metal ions present. This study found that copper ions accelerate and complete the curing process more effectively than iron, reducing the activation energy required and enhancing the adhesive's performance.
