Normal cholesteric liquid crystal films reflect light only in a very narrow band of wavelengths, but Chelix has developed proprietary CLC film technology that reflects broad bandwidths of light in the infra-red (IR) spectrum. This is accomplished by constructing a continuously varying pitch of the the liquid crystal molecules in the material.

Chelix is currently developing improved CLC systems that combine both right- and left-handed CLC films to reflect nearly 90% of incident radiation with wavelengths ranging from 800 to 1600 nm. The spectral reflection quality of our two-handed CLC films is illustrated in the following graph:

Manufacturing

Chelix Solar Control Films are applied to PET and other substrates through a traditional UV wet coating process, very similar to the process of making acrylate hard coats on current solar films. A typical Solar Control Film construction is shown below. Our CLC systems may also serve as an interlayer adhesive and protective coating for metallization layers.
