ABSTRACT:
Coated pellets are produced by forming pellets having about 20% or more void space, contacting the pellets with a suspension of polymeric particles, reducing the temperature of the particles to create a pressure differential between the voids and the atmosphere to draw in liquid from the suspension and filter polymeric particles on the surface to form a coating.
