Powder  coating,  literally  speaking,  is  a  type   of  coating  in  the   form  of  100% powder.Comparing to Convectional paint, Powder Coating does not contain any liquid

carrier. It is sprayed onto the substrate surface in powder form, then baked, melted, leveled and cured to form a thin film.

There are two producing methods using special effect pigment into powder coating: dry mixing and bonding. When special effect pigment is used, the powder coating producers  could  face  issues  such  as,  gun-blocking,  little  coating  dosage,  uneven surface  and  so  on.  These  issues  are  universal;   it  prevents  the  powder   coating manufactures feeling free to use special effect pigments in their designs.
