Finally, ensuring that manufacturers of waterborne aluminium-silver pastes are able to provide consistent batch quality is key to guaranteeing the stability of the final product. The production process of aqueous aluminium-silver pastes involves the selection of raw materials and control of the production process, so quality fluctuations from batch to batch may affect the performance and effectiveness of the final coating. Enterprises should select suppliers that can provide batch quality traceability and stability, and conduct incoming tests on the arrival of each batch, including metal content, particle size distribution, viscosity, specific gravity and other indicators. Regular testing helps to ensure the consistency of the aluminium silver paste, thus avoiding unqualified products due to quality fluctuations.
