New safety glass technology reflects 50% of solar radiation and transmits 70% of visible light. A non-micellar twisted nematic liquid crystal features cholesteric near-infraredreflecting properties, along with at least one near-infrared absorptive material. The composition can be used as a layer — optionally in conjunction with polymeric films, polymeric sheets, and rigid sheets — to form multilayer laminates. The multilayer shields are useful as solar control windows to reduce energy consumption and cool the interior of automobiles or buildings.
The polymer sheet has a modulus of less than 20,000 psi as measured by ASTM Method D-63. The laminates also include an adhesive or primer on at least one surface of the non-micellar layer, wherein the adhesive or primer results in a shift in the wavelength of peak reflection of greater than 30 nm.Get the complete report on this technology at:
