STEK Automotive, a U.S-based film technology developer, has launched a premium nano-ceramic window film, NEX, that contains graphene as well as tungsten and antimony tin oxide.
The graphene-enhanced nano-ceramic window films are said to provide crystal clarity as well as UV and glare reduction, and is said to effectively prevent heat from reaching vehicle interiors. Its metal-free structure also reportedly guarantees signal freedom, ensuring the continuous connectivity of all electronic devices. By blocking up to 95% of visible interior light, NEX additionally offers exceptional passenger privacy, while its 92% sun glare reduction rate dramatically reduces eye strain. With a 98% IR rejection rate, NEX's steady regulation of UV transmittance keeps windows cool, significantly reducing the level and intensity of deterioration.
The company's website states that nanoparticles of tungsten and antimony tin oxide (ATO) are dispersed throughout NEX’s proprietary structure. These materials are known infrared absorbers, which effectively prevent heat from reaching the window’s interior. NEX also contains graphene, which dramatically accelerates the rate of heat dissipation.
