Abstract: The invention provides a layer of fluoropolymer having dispersed therein infrared absorbing particles as a low emissivity layer to reduce the amount of cooling or heating required to maintain a desired temperature for an interior space. The invention also provides a low emittance article comprising a substrate having on at least one major surface thereof at least two layers, the outermost layer of which comprises a fluoropolymer and IR-absorbing particles in the form of flakes distributed in the outermost layer. The invention further provides a composition for producing a low emissivity coating, the composition comprising a dispersion of a fluoropolymer and IR-absorbing particles in the form of flakes. The invention also provides a process for reducing the amount of cooling or heating that is required to maintain a desired temperature for an interior space.
