Abstract
In a method of improving the weathering of a bituminous coating, a microwave-produced carbon black is added to the coating. The microwave-produced carbon black is added in an amount sufficient to increase the cycles-to-failure of the coating by at least about 10% compared to the same coating without the added microwave-produced carbon black, when tested for weathering according to ASTM D 4799-00.
