Abstract:
1. A method for powder coating comprising: mixing a powder coating composition using an acoustic mixing process to form a homogeneous dry powder; and applying the homogeneous dry powder to a substrate via an electrostatic gun to form an outer layer having a surface gloss of between about 5 ggu and about 45 ggu when measured at 75° C., wherein the powder coating composition comprises a mixture of a first material and a second material and the first and second materials have different densities, wherein the substrate is grounded, and wherein the electrostatic gun comprises at least one electrode and a high-voltage generator, and the high-voltage generator generates a negative polarity voltage between about 0 KV and about 100 KV that is applied to the electrode during application of the homogeneous dry powder.
