Chitec Technology, in partnership with its authorized South Korean distributor Infochems, jointly participated in ATEM FAIR 2026. The event featured two core product series: blue light absorbers and triazine UV absorbers, engaging in deep discussions with industry clients across optical materials, electronic materials, functional coatings, and high-performance polymers regarding the latest material development demands.

Through exchanges at the exhibition, Chitec observed that the development focus for high-performance materials is rapidly shifting toward comprehensive spectral management. Optical materials are no longer just aiming for basic blue light absorption; instead, they place greater emphasis on precise control over specific cutoff wavelengths to strike an optimal balance between transmittance, yellow index (color shift), and overall optical quality. On the other hand, long-term weatherability and UV stability have become critical metrics for evaluating optical materials, presenting new design challenges in maintaining long-term optical performance. Furthermore, as reliability requirements continue to rise in electronic materials, high-performance coatings, and engineering plastics, reactive UV absorbers are gaining market attention as a key technology to enhance long-term durability and product reliability.

Optical Materials Shift Toward Precise Spectral Management, Balancing Cutoff Wavelengths and Optical Quality

Optical material applications remained the most highlighted technical focus during this year's exhibition.

Throughout the event, market demand for blue light absorption technology was observed evolving from simple energy reduction toward precise cutoff wavelength tailoring. Driven by diverse application scenarios and optical specifications, end products now demand customized cutoff positions—aiming to boost blue light blocking efficiency while preserving high transparency, low color shift, and superior optical clarity.

This trend is particularly evident in the development of Optically Clear Adhesives (OCA), protective films, and other transparent optical substrates. Beyond meeting specific wavelength cutoffs and optical specs, the market is placing far greater emphasis on the long-term light stability and weatherability of blue light absorbers under continuous illumination.

Additionally, as target cutoff wavelengths extend into longer visible light regions, balancing spectral precision with clarity and color neutrality becomes increasingly challenging. Since different blue light absorbers vary in weatherability, spectral stability, and formulation compatibility, achieving an ideal balance between cutoff efficiency, transparency, and long-term reliability has emerged as a core challenge in optical material design.

To address diverse material systems and application requirements, Chitec continues to innovate custom blue light absorbers with targeted absorption bands. By optimizing weatherability, solubility, and system compatibility, Chitec offers tailored product selection, spectral analysis, and formulation evaluation. We help clients build complete spectral management solutions that deliver high cutoff efficiency, excellent clarity, processing stability, and long-term weatherability across OCA, display materials, optical films, and advanced optical components.

Upgrading Weather-Resistant Materials with an Increased Emphasis on Long-Term Reliability

In addition to optical applications, high-durability materials remained a key topic of discussion during the exhibition.

Although certain end markets continue to face cyclical economic adjustments, industry R&D investments in high-durability products remain strong. Discussions revealed that sectors including high-performance powder coatings, industrial coatings, engineering plastics, and functional materials are actively upgrading products to optimize long-term weatherability—underscoring material reliability as a decisive competitive edge. Chitec highlighted its triazine-based UV absorber technology, providing comprehensive light stabilization solutions tailored to various polymer matrices and application requirements. Featuring outstanding UV absorption efficiency, thermal stability, processing compatibility, and long-term weather resistance, Chitec's solutions help materials retain their transparency, aesthetic appearance, and mechanical strength over time, while offering versatile spectral choices for high-clarity, long-life, and weather-resistant applications.
