Summary

The compositions of polyester powder paint BFP and selected nanofillers: modified bentonite and silica modified with 3-(trimethoxysilyl)propyl methacrylate were prepared using aco-rotating twin-screw extruder. The obtained compositions were applied to metal plates. It was found that the coatings prepared from the compositions of powder paint, nanofillers and additives showed much better performance (gloss, relative hardness, impact resistance, ductility, scratch resistance, adhesion to substrate and shear strength) compared to the coating obtained using unmodified powder paint.
