Discolor Water Sensitive Label Features
The Discolor Water Sensitive Label uses a hydrochromic dye system that undergoes an irreversible color shift the moment liquid water dissolves and migrates through the coating.
This produces a clearly visible, permanent stain that serves as objective evidence of moisture exposure. The label remains visually unchanged in dry environments, making it suitable for embedded monitoring inside enclosures and packaging.
Vizlent manufactures the Discolor Water Sensitive Label across a range of sizes, color combinations, and shapes to support diverse industrial monitoring needs. The thin, flexible construction conforms to curved surfaces, while the strong acrylic adhesive secures the label against vibration and handling.

Frequently Asked Questions
Yes, we customize diameter, die-cut shape, and color transition pairings. The most common is white-to-red, but white-to-blue and other combinations are available based on volume. Share your specification and we will quote samples for evaluation.
Under normal ambient humidity up to about 85% RH (non-condensing), the label remains visually stable and does not falsely discolor. Activation requires direct contact with liquid water or condensed droplets sufficient to dissolve the dye coating. We humidity-test each batch to ensure dormancy.
Our standard MOQ is 10,000 pieces with production typically completed in 7 to 12 working days. Trial quantities can be arranged for first-time customers. Repeat orders of standard sizes often ship within a week thanks to maintained stock.
No, the discoloration is permanent and will not revert when the label dries. This irreversibility is essential for after-the-fact moisture detection and warranty disputes. VIZLENT specifically engineers the dye chemistry to resist reset attempts.
The permanent acrylic adhesive bonds well to most clean, dry surfaces including ABS, polycarbonate, painted metal, stainless steel, glass, and PCB laminates. For low-surface-energy plastics like PE or PP we recommend evaluation samples first. We can also recommend or formulate alternate adhesive options.
