March, 2006
Product Description
3M™ Water Contact Indicator Tape 5557NP quickly shows indication when
contacted by water. When water comes in contact with the tape surface, it rapidly
changes from white to red.
The tape is designed to withstand heat and humidity
aging without giving false indication. It will continue to show indication even after
prolonged submersion in water. The adhesive is a high performance acrylic
protected by a silicone coated film release liner.
