EXAMPLE 4
Sample 4

The same coating as in Example 3 was prepared for coating 100 gm of the same mineral particles as in Example 3, except the method of application was different. More specifically, the graphene was not added directly into the coating. The sodium silicate coating without the graphene was first mixed with the granules or the mineral particles in a tumbler for about one minute, and then dry graphene powder was added via an air brush spray as the mixing continued. After uniform mixture was observed, the granules were then heat treated at 500° C. to cure the coating. The CIE LAB color data for the finished granules was measured. The total solar reflectance for the finished granules was measured according to ASTM E903.
