[PDF]2021-11-9 type of powder coating. Partially due to the wide difference in specific gravity between aluminum (2.7 g/cc) and the powder coating (1.2-1.6 g/cc), some phase separation occurs during the recycling of over-spray material. This, therefore, leads to the recycled material having a different composition and appearance compared to the virgin material.
