Company overview

Inkron, a Nagase Group Company, develops and manufactures advanced siloxane-based formulations and resin systems for Optical Devices, Opto Packaging and Printed Electronics. Inkron’s core technology is centered around siloxane resins designed and synthesized in-house with advanced formulation knowhow. These optically clear resins are thermally and optically stable providing a perfect platform for the targeted applications. Advanced formulation steps facilitate meeting the various application-specific needs.

Inkron has its primary manufacturing and R&D location in Finland. The optoelectronics and opto-packaging departments are in Taiwan. Inkron has worldwide representation.


The main application fields are found within the Opto Packaging, Optical Devices and Printed Electronics industries. The product range includes high and low Refractive Index (RI) coating materials for application in optical devices. These industry-leading optical coatings cover a record-breaking RI range between 1.1 and 2.0 for the VIS/NIR spectrum. The high RI materials are optimized for Nano Imprint Lithography (NIL). Target applications include DOE (Diffractive Optics Elements), like waveguides for AR/XR devices, optical diffusers, LIDAR and other photonic applications. Complementing the high refractive index materials are Inkron’s matching low refractive index materials with an RI range of 1.1-1.4. Typical applications of the low RI materials are found in anti-reflective coatings (visible and NIR range), waveguide claddings and adhesive layers. For opto-packaging applications (like LED and sensors) Inkron provides high-RI, UV-curable encapsulants as well as thermally conductive adhesives. The product range equally includes screen- and inkjet-printable stretchable conductive and insulative inks and adhesives for use in Printed Electronics applications such as Wearables and In-Mold-Electronics.
