Liquid Sensitive Indicator Labels
Liquid Sensitive Indicator Labels (LCI) are precision-engineered moisture detection markers used by OEMs to confirm whether a device has been exposed to water.
The hydrochromic active layer reacts on contact with water or water-based liquids, producing an immediate and permanent red signal that cannot be cleared by drying. This makes Liquid Sensitive Indicator Labels a trusted tool for warranty assessment and quality control.
Vizlent produces LCI labels in a wide range of micro-sizes and custom shapes for hidden placement within smartphones, batteries, and other compact electronic assemblies. The labels are supplied on precision liner systems compatible with high-speed automated application equipment.

Frequently Asked Questions
Yes, we routinely produce liquid contact indicators down to about 2 mm with precision die cutting. Custom logos, micro-text, and serial numbering can also be added for brand protection. Share your placement zone dimensions and we will recommend a feasible size and tolerance.
The labels react reliably to water and water-based liquids such as sweat, beverages, and many cleaning solutions. Pure oils and certain non-aqueous solvents may not trigger the same color response. If you have a specific liquid in mind, VIZLENT can run targeted compatibility tests on samples.
Our standard MOQ is 10,000 pieces, with bulk pricing available at higher volumes. Lead time is typically 7 to 12 working days after artwork and shape approval. For high-volume OEM customers, we can arrange scheduled releases against a blanket order.
Yes, once triggered, the white-to-red change is permanent and cannot be reversed by drying, heating, or normal cleaning. Combined with custom logos and serialization, this makes the LCI label difficult to swap or counterfeit. VIZLENT customers rely on this attribute for fair, evidence-based warranty decisions.
Yes, we wind the labels on rolls with consistent gap spacing, liner thickness, and core size suited to automated dispensers and pick-and-place machines. Roll direction and label pitch can be adjusted to match your specific equipment. We also support manual application with sheet or kiss-cut formats.
