CA 2482112
The invention relates to a substrate (1) with a first coating (2), comprising at least one hydrophilic layer based on a derivative of at least partially oxidized silicon, covered by a second photocatalytic coating (3) comprising at least partially crystalline titanium oxide with a discontinuous/permeable structure. The invention further relates to application of said substrate to a glazed unit, a building material or a mineral wool.
L'invention concerne un substrat (1) muni d'un premier revêtement (2) comportant au moins une couche hydrophile à base de dérivé au moins partiellement oxydé du silicium, surmonté d'un second revêtement (3) photocatalytique comportant de l'oxyde de titane au moins partiellement cristallisé et présentant une structure discontinue/perméable. Application de ce substrat à un vitrage, un matériau architectural, une laine minérale.
