  • the amount of azole compounds of the formula (I) necessary for the stabilization depends on the type and amount of the drier used, the alkyd resins and other constituents in the color formulation.
  • the amount In the case of alkyd resin paints, the amount must be adjusted so that the iodine-containing biocides do not degrade, but the actual effect of the dryer is not suppressed.

Abstract

Des composés de type azole particuliers, notamment des imidazoles, triazoles ou tétrazoles, conviennent remarquablement bien pour la stabilisation de biocides contenant de l'iode, en particulier, des composés iodoalkinyles, iodoalcényles ou iodoalkyles, dans des matériaux techniques, notamment dans des peintures à base de résines alkydes.
