Abstract
A powder containing a polyoxymethylene polymer for coating metallic substrates is described. The polymeric particles are made from a polymeric composition containing a polyoxymethylene polymer having functional terminal groups. The polyoxymethylene polymer is blended with at least one functional additive. The functional additive can decrease the stiffness of the polyoxymethylene polymer, can decrease the shrinkage properties of the polyoxymethylene polymer and/or increase adhesion of the polymer to metal surfaces.
