Water Contact Indicator Labels

Water contact indicator labels provide a visible colour change (e.g., white to red) when exposed to liquids, helping signal potential water ingress on devices, packaging or documents.

Function: colour shift on contact with water/condensation for exposure evidence.
Formats: circular and rectangular labels in various diameters and sizes.
Adhesives: options suited to cardboard, plastics, metals; writable or codable areas available.
Use cases: electronics, packaging, service documentation, assets and containers.

Note: these are not “waterproof labels”; they are designed to indicate liquid exposure, not to resist it.
