  • Method for reducing temperature rise of heat sensitive substrates
    Patent number: 4546045
    Abstract: A method is described for reducing the temperature rise associated with sunlight exposure of non-metallic substrates, more particularly heat sensitive polymeric substrates. The method involves coating the substrate with a coating composition comprising a film-forming polymer and an effective amount of an infrared reflective pigment, said coating composition having a CIELAB L* value of up to 70 and resulting in the coated substrate reflecting at least 45 percent of impinging infrared energy. Also described is a coated article prepared the aforedescribed method.
