Tekra Introduces Marnot Advanced Low Iridescent (LI) Polyester to the LI Line of Hardcoated Films

Tekra is proud to announce the addition of Marnot Advanced™ LI Polyester to the Marnot Advanced™ LI portfolio of hardcoated films.

Nothing is more distracting than iridescence, which is that rainbow phenomenon and non-uniform pattern that is caused by the interference of lights across the hardcoated surface. Iridescence is a problem in today’s hardcoated films, and is especially prominent with opaque white and jet black printed parts used in the appliance industry. To minimize the effect of iridescence across the hardcoat, Tekra is the first to introduce a low iridescent hardcoat, however until now this has only been available at Tekra on polycarbonate film.

By using refractive index matching technology, Tekra has now introduced a polyester version, called Marnot Advanced LI Polyester. The new Marnot Advanced LI Polyester provides the same benefits as Marnot Advanced Polyester, with added low iridescent performance. According to Damian Maninno, Tekra’s Market Development Manager for Hardcoated Films, “Marnot Advanced LI Polyester and Polycarbonate brings a new level of design flexibility to appliance overlay, membrane switch, faceplate, and control panel applications.”

Additional features include:

-Heat stabilized polyester provides dimensional stability
-Excellent visual acuity and color brightness
-Superior chemical resistance, including sunscreen and DEET
-Printable with UV and solvent based inks
-Process flexibility: 1st surface texturable, embossable, and diecuttable
Marnot Advanced LI Polyester is available in a 7 and 10 mil thickness at a web width of 49” and in 48” x 24” sheets. Tekra can also convert to any roll size or sheet needed.

Marnot Advanced™ Low Iridescent (LI) is the appliance industry’s first hardcoated product line to virtually eliminate iridescence, a common problem found in other hardcoated films. Iridescence is that unsightly rainbow phenomenon that can be seen at the surface of a film when viewed at certain angles. By using refractive index matching technology, Tekra has developed a low iridescent polycarbonate and polyester hardcoat to combat this very issue.

Tekra’s improvement to iridescence with Marnot Advanced LI Polycarbonate and Polyester is best seen after printing opaque white and jet black inks, which are the most used colors in appliance overlay applications.
