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.
Claims28
A radiation-control sheet material comprising:
- a transparent support carrying means for reflecting infrared radiation;
- and as a protective outer layer for said radiation-control sheet material, a polymeric layer substantially transmissive of infrared radiation, said polymeric layer having therein or as a layer contiguous thereto an effective amount of an isocyanate adhesion-promoting agent.
A radiation-control sheet material comprising:
- a transparent support carrying means for reflecting infrared radiation and at least one antireflection layer of dielectric material contiguous thereto;
- and as an outer protective layer for said radiation-control sheet material, a polymeric layer substantially transmissive of infrared radiation, said polymeric layer having therein or as a layer contiguous thereto an effective amount of an isocyanate adhesion-promoting agent.
