The Custom Water Sensitive Sticker is a precision-engineered Water Damage Indicator (WDI) designed to detect liquid exposure in electronic devices and warranty-controlled products. Manufactured from water-activated sensitive paper material, this indicator label irreversibly changes color upon contact with water or moisture, providing a clear and tamper-evident record of liquid intrusion.
These stickers are widely used in smartphones, computers, earphones, cameras, and PCB assemblies, helping manufacturers and service centers quickly identify liquid damage, reduce warranty fraud, and streamline after-sales inspection and decision-making.
