Secondly, the storage and shelf life management of water-based aluminium silver paste is crucial. Aluminium-silver pastes can maintain good stability if they are not mixed with other ingredients and are stored under conditions that meet the requirements of sealing, drying and ventilation. However, once aluminium-silver paste has been mixed with other ingredients to formulate a water-based paint, the types and proportions of additives may have an impact on its stability, especially in environments with large variations in temperature and humidity. Therefore, temperature resistance tests and aging experiments should be carried out before use to ensure that the paint maintains its desired performance and appearance during long-term storage.
