A primer and/or pretreatment coating composition comprising: (a) an adhesion promoting component; and (b) corrosion resisting particles selected from: (i) magnesium oxide particles having an average primary particle size of no more than 100 nanometers; (ii) particles comprising an inorganic oxide network comprising one or more inorganic oxides; and/or (iii) chemically modified particles having an average primary particle size of no more than 500 manometers. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi- component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.
L'invention concerne des compositions de revêtement comprenant des particules résistant à la corrosion de sorte que la composition de revêtement peut présenter des propriétés de résistance à la corrosion. L'invention concerne également des substrats au moins partiellement revêtus d'un revêtement déposé formé à partir de ladite composition ainsi que des revêtements composites à composants multiples, au moins une couche de revêtement déposée étant formée à partir de ladite composition de revêtement. L'invention concerne enfin des procédés et un appareil pour la production de particules solides ultrafines.
