Coating compositions that transmit infrared radiation and exhibit color stability and related coating systems |
| 摘要 |
A coating composition suitable for producing coatings that are transparent to infrared radiation and can exhibit color stability, such as a jet black color. The coating compositions include a first tint having a low haze and a second tint having a high haze. The tints include visibly absorbing infrared transparent pigments. |

1. A coating composition comprising:
(a) film-forming resinous binder; (b) a first visibly absorbing infrared transparent low haze pigment, wherein the first visibly absorbing infrared transparent low haze pigment has an average primary particle size of no more than 100 nanometers; and (c) a second visibly absorbing infrared transparent high haze pigment different from the first visibly absorbing infrared transparent low haze pigment, wherein the second visibly absorbing infrared transparent high haze pigment has an average primary particle size of at least 200 nanometers, and wherein a cured coating deposited from the composition:
(i) has a jetness of at least 240, and(ii) exhibits a color change of no more than 1ΔE unit after 3000 hours of QUV durability testing. |
