3M
Water Contact Indicator Tapes provide a fast, accurate and easy way to positively detect water intrusion into sensitive electronic devices. This family of products offers excellent temperature and humidity resistance, while quickly turning bright red on contact with liquid water. The red color change is irreversible after drying. 3M Water Contact Indicator Tapes are long lasting, and have shown exceptional resistance to wash-out and bleach-out from strong oxidizers.
3M Water Contact Indicator Tape 5557 is the workhorse of this product family, and
offers a comprehensive package of environmental stability, indication speed, total caliper
and printability.
3M Ultrathin Water Contact Indicator Tapes 5558 and 5559 offer a thinner total
caliper, where tight geometries dictate a very low thickness water indicator product
3M Water Contact Indicator Tape 5557NP is a new addition to this family. The product
retains most of the premium attributes of 5557 indicator tape, while offering enhanced
indication speed through removal of the top film layer.
3M Water Contact Indicator Tape 5559i has the same attributes as tape 5559 except the adhesive is on the top side for viewing through transparent substrates, which may be used in certain product designs.
