Irreversible Water-Red Indicator Label, Red Color Change (CAT#: STEM-BC-3282-ZJF)

This water-sensitive security label is designed to indicate liquid contact on electronic and industrial products. Its surface changes to red when the label material is fully exposed to water. The resulting color change is irreversible and remains visible after the material dries. This permanent indication supports product tracing, warranty assessment, and responsibility determination. The label is especially useful where internal liquid damage is difficult to identify during servicing. It can be applied to mobile phones, batteries, LCD products, electronic devices, appliances, and circuit assemblies. The material is sensitive to moisture and can reveal abnormal liquid exposure. Thermal-transfer barcode printing and customized label dimensions are supported.
