Functional hard coated film HA series (with adhesive)・H series
Various functions can be added by thin film wet coating technology. Wide variety of coating formulations are available for various applications.
In addition to the clear type, low reflection type and anti-glare type, we also have a lineup of special grades that improve the writing quality of the touch pen.
HA series (with adhesive)
We are able to support a variety of applications by combining our core technologies of “Surface Modification Technology,”
“Adhesive Technology,” and “Release liner Technology.”
Various films such as streched plastic films and cast films are used as base film.
Various technologies for functional hard coated films
Suppresses the decrease in visibility from the reflection of outside light on the screen.
For anti-glare type, we offer a line-up of high anti-glare and high-definition grades.
(High anti-glare type)
(High definition anti-glare type)
Applying to high-definition displays enables suppression of dazzle.
We have two approaches as below for fingerprint-resistant films which are applied to the surface layer of displays.
Water-repellent type (fingerprint removability)
Water contact angle
Contact angle Water:105.6°, Oleic acid:68.4°
Lipophilic type (makes fingerprint smudges less noticeable)
Oleic acid contact angle
Contact angle Water: 60.6°, Oleic acid: 20.8°
Anti-water marking and anti-Newton ring type
Water marks that occur in air gap–type touch panel devices lead to a drop in the visibility.
In our coating products, the material designs take into account of the suppression of interference fringes.
Special function (improved writing feel) type
Tablet PCs for educational purposes and other devices that allow writing on the screen with a touch pen have become widespread. In order to make writing on them feel natural, we focused on the resistance and vibration when writing with a pencil on paper.
