Abstract

1451080 Coated products AMERICAN CYANAMID CO 1 Jan 1974 [12 Jan 1973] 1445/74 Heading B2E [Also in Divisions Cl, C3 and C7] An infrared attenuator comprises a substrate of glass or organic polymer capable of transmitting at least 10% of incident visible light of wavelength less than 0.65 micron, the substrate being coated on at least one surface with cadmium stannate of conductivity greater than 1.0 x 10<SP>3</SP> ohm<SP>-1</SP>cm<SP>-1</SP>. The substrate preferably has a temperature coefficient of thermal expansion of less than 20 x 10<SP>-6</SP>(‹C)<SP>-1</SP> and may particularly be of glass, quartz or polyimide. When the coefficient is above this value (e.g. for a polymethylmethacrylate substrate), a transparent interlayer consisting of a polymeric mixture having a glass transition temperature of below 30‹C (especially a polyvinylidene fluoride/polymethyl- or ethyl-methacrylate mixture) is hot-pressed onto the substrate prior to coating. Known near-infrared adsorbers such as ferrous oxide and hexafluoroantimonates may be included in the cadmium stannate coating. In the Examples, the coating is applied by sputtering in an argon atmosphere and may be subsequently heated in H 2 to alter its conductivity.
