Abstract
Abstract Radiation-control sheet materials are disclosed, these materials including a transparent support material, an infrared radiation-reflecting layer and a protective polymeric layer therefor substantially transmissive of infrared radiation and having therein or in a layer contiguous thereto an adhesion-promoting isocyanate. The protective polymer layer provides anti-abrasion and anti-corrosion protection and is effectively bonded by the adhesion-promoting isocyanate.
