Title (EN) HIGH VOLUME SOLIDS FLUOROCARBON COATINGS
(FR) REVETEMEMTS FLUOROCARBONES A TENEUR EN SOLIDES DE VOLUME ELEVE
Abstract:
(EN) The invention provides thermosetting coating compositions in which acrylic copolymers are used as carriers for fluorocarbon resins. The compositions have a combination of high fluorocarbon content, high solids content, and a low viscosity suitable for coil coating. Thus, the solids are borne in organic solvent systems which permit minimization of the viscosity and a moderate evaporation rate. The solvent system has a $g(d)H of from 1.7 to 2.6 (calories/cubic centimeter)1/2 and a $g(d)V of from 8 to 9.5 (calories/cubic centimeter)1/2 and is exemplified by a mixture of 4 or more of the following solvents: aliphatic ketones having from 4 to 10 carbon atoms, alkyl esters having a total of from 5 to 7 carbon atoms, aromatic acid esters having from 8 to 12 carbon atoms, lactones, and aromatic solvents. The acrylic polymer is comprised of (a) acrylic esters having no additional functionality, (b) acrylic esters having additional functionality by which the acrylic polymer may be cross-linked, and (c) an acryloxyalkyl oxazolidine.
(FR) Cette invention se rapporte à des compositions de revêtement thermodurcissables, dans lesquelles des copolymères acryliques sont utilisés comme véhicules pour des résines fluorocarbonées. Ces compositions combinent une teneur élevée en fluorocarbures, une teneur élevée en solides et une faible viscosité, qui les rendent aptes comme revêtements pour bobines. Ainsi, les particules solides sont en suspension dans des systèmes de solvants organiques qui permettent de réduire au minimum la viscosité et de modérer la vitesse d'évaporation. Ce système de solvants possède une valeur $g(d)H comprise entre 1,7 et 2,6 (calories/centimètre cube) et une valeur $g(d)V comprise entre 8 et 9,5 (calories/centimètre cube) et se caractérise par un mélange d'au moins quatre des solvants suivants: des cétones aliphatiques ayant 4 à 10 atomes de carbone, des esters d'alkyle ayant un total de 5 à 7 atomes de carbone, des esters d'acide aromatique ayant 8 à 12 atomes de carbone, des lactones et des solvants aromatiques. Le polymère acrylique est constitué par (a) des esters acryliques n'ayant pas de fonctions additionnelles, (b) des esters acryliques ayant une fonction additionnelle par laquelle le polymère acrylique peut être réticulé, et (c) une oxazolidine acryloxyalkyle.
