FEATURES
- Film top layer is printable by thermal transfer, flexographic, and screen printing methods and offers improved ink receptivity
- The film top layer also provides protection from soiling and moisture during handling
- Paper backing is highly absorbent and transports water to show indications
- Acrylic adhesive allows for a very high bond strength to most surfaces including low surface energy plastics such as polypropylene and powder coatings
- Total construction is rotary die cuttable
- Tape is thinner to enable slim electronics device design
APPLICATIONS
- Use as a water contact indicator in handheld or portable electronic devices such as smart phones, tablets and
phablets, laptop computers and keyboards, wearable electronic devices, gaming and MP3 players, two-way
