Currently, most dark colored paints use carbon black as a pigment. Carbon black is very opaque, and has excellent coverage properties. But carbon black is extremely absorbing of infrared as well as visible light energy. To improve reflectance of dark colored paints, carbon black must be removed or substantially reduced. Staff investigated pigment choices that are currently available or under development to replace carbon black. Unfortunately, while many solar reflective “blackish” pigments are available, none offer the excellent hiding performance or true jet black color that is obtained through the use of carbon black. In addition, these pigments tend to be much more expensive than carbon black. Therefore, although staff believes that solar reflective paint can and should be developed for automotive use, staff was unable to clearly identify a technology path at this time that would lead to improved solar performance with acceptable color choices, costs, and ease of application. Staff believes that this approach should be further considered for a future rulemaking but that it is premature to include solar reflective paint herein.

Hold the revolution! Due to the above it looks like the legislation is focusing on window glazing for now.
