Title
(EN) TREATED INORGANIC PIGMENTS HAVING REDUCED PHOTOACTIVITY AND IMPROVED ANTI-MICROBIAL PROPERTIES AND THEIR USE IN COATING COMPOSITIONS
(FR) PIGMENTS INORGANIQUES TRAITÉS AYANT UNE PHOTOACTIVITÉ RÉDUITE ET DES PROPRIÉTÉS ANTIMICROBIENNES AMÉLIORÉES ET LEUR UTILISATION DANS DES COMPOSITIONS DE REVÊTEMENT
Abstract
(EN)
The disclosure provides a coating composition comprising a treated inorganic particle having reduced photoactivity and improved anti-microbial properties, wherein the treated inorganic particle comprises: an inorganic core particle; a first treatment of a silicon compound, wherein the silicon compound is added in a single step; and a second treatment comprising co-precipitated zinc oxide and alumina.
(FR)
La divulgation concerne une composition de revêtement comprenant une particule inorganique traitée ayant une photoactivité réduite et des propriétés antimicrobiennes améliorées, dans laquelle la particule inorganique traitée comprend : une particule de noyau inorganique ; un premier traitement d'un composé de silicium, dans lequel le composé de silicium est ajouté en une seule étape ; et un second traitement comprenant de l'oxyde de zinc et de l'alumine coprécipités.
