ABSTRACT:
This invention concerns an agglomeration of particles to be used as additives for moulding thermoplastic polymers or paints, said agglomeration being in the form of chips, flakes, powder or paste in which a coating with a carrier of said particles is provided that moves in between the particles to keep them essentially separate from one another, said particles being substantially coated all over their surface. The invention also concern a method to obtain the particles coating with a carrier substantially all over the surface of said particles in form apt to be additivate to moulding thermoplastic polymers or paints in order to obtain flatting of moulded pieces with said thermoplastic polymers or painted with said paints said agglomeration being in the form of chips, flakes, powder or paste, characterized by the fact that said particles are mixed with said carrier in powder to obtain a mixture, said mixing occurring at a temperature which is close, but lower then melting point of said carrier, in order to provoke an adhesion of speck of said carrier on the surface of said particles.
