Abstract: The present invention is directed to a powder coating composition that produces a low gloss coating upon cure. The powder coating composition includes one or more crosslinkable base polymer, a crosslinkable acrylic polymer and one or more free radical initiators. By adding spheroidal particles to the powder coating composition further reduction in gloss can be obtained while improving smoothness. These compositions are well suited to produce coatings on metallic substrates, such as automotive bodies and non-metallic substrates, such as reconstituted wood substrates, used for desk or table tops.
