Water Contact Indicator Tape

3M water contact indicator tape 5557 is a 10.2 mil thick, printable, self-adhesive product that shows area specific, long lasting indication of contact with water. When liquid comes in contact with the product, the color rapidly changes from white to red. This product is designed to withstand heat and humidity aging without giving water indication and it will continue to show indication, even after prolonged submersion in water. The construction is readily die-cuttable, making small custom shapes easy to produce. The adhesive is a high performance acrylic protected by a silicone coated film release liner.
