The Water Damage Labels will turn red quickly when meeting water

Features:

Once liquid water has penetrated, the label will be visibly discolored and cannot be retrieved.
Labels can be designed to change color or completely submerge at a preset relative humidity.

How does this work?

Diffusion: Preset graphics that spread rapidly upon contact with water
Decolorization: Once the liquid water invades, the primary color will quickly decolorize, and the preset color will be revealed

Application:

Water damage labels are widely used in warranty marking of mobile phones, mobile phones, batteries, electronic products, electrical appliances, and LCD monitors. Provide concrete evidence for hard or misidentified repair services following water damage or substandard controls.
