COATING COMPOSITIONS PROVIDING IMPROVED MAR AND SCRATCH RESISTANCE AND METHODS OF USING THE SAME

Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the c...

Zusammenfassung:	Disclosed is a coating formed from a composition containing a film-forming resin and a plurality of particles dispersed in the resin. The average particle size of the particles is 0.1 to 50 microns, and the particles have a hardness sufficient to impart greater mar and/or scratch resistance to the coating as compared to a coating where no particles are present. Also, the difference between the refractive index of the resin and the refractive index of the particles ranges from 1 to 1.5. A method for preparing a powder coating including the particles also is provided. L'invention concerne un revêtement obtenu à partir d'une composition contenant une résine filmogène et une pluralité de particules dispersées dans ladite résine. La dimension particulaire moyenne des particules est comprise entre 0,1 et 50 microns et les particules présentent une dureté suffisante pour assurer au revêtement une meilleure résistance à l'endommagement et/ou à l'abrasion, comparativement à un revêtement ne comportant pas de particules. La différence entre l'indice de réfraction de la résine et l'indice de réfraction des particules est comprise entre 1 et 1,5. L'invention concerne également un revêtement pulvérulent contenant lesdites particules.
