Abstract

Les compositions de revêtement de l'invention, dans lesquelles se produit une séparation, contiennent au moins 75 % et jusqu'à 100 % en poids de solides, et se composent d'un composant de revêtement supérieur formant un film contenant du fluor, du chlore et/ou du silicium et un composant de couche de base approprié. Des systèmes bicouches ont été obtenus lorsque se présente une différence valable de la viscosité de cisaillement zéro et de l'énergie superficielle entre les deux composants. De préférence, la viscosité de cisaillement zéro, au niveau de la fluidité maximum du composant de couche supérieure, n'excède pas 3 Ln Pa.s de celle du composant de couche de base. Les composants de couche supérieure peuvent être thermoplastiques ou thermodurcissables, et ont de préférence un ou plusieurs groupes terminaux pendants, à teneur élevée en hydrocarbure et contenant du fluor, du chlore, du silicium et/ou C4. Des polymères dérivés des séries Zonyl de monomères ont été notamment utilisés et ont, par exemple, produit une excellente séparation dans des systèmes contenant du solvant présentant des teneurs très élevées en solides (> 90 % en volume) et dans des systèmes contenant 100 % de solides (compositions de revêtement en poudre).
