Product Details: ACA-50-166

UV sensors. Ultraviolet (UV) radiation sensitive labels change from yellow to red when exposed to 3.5 MEDs of UV light. The labels can be printed, die cut, sheeted and custom packaged with graphics of your choice.

For best adhesion, the UV Sensors should be applied to a clean, dry surface. They may be worn on clothing, clean skin, or applied on surfaces that have sunlight exposure similar to the wearer.

Shelf life is over 2 years if the UV Sensors are kept in the sealed packages and kept away from extreme heat and humidity.
