Abstract:
The present invention relates to compositions with self-cleaning properties. More particularly, the invention concerns coatings or paints comprising particles coated with a catalytically active composition. In particular, a self-cleaning coating composition (paint) is provided, comprising micro-sized particles coated with a functional layer, wherein the micro-sized particles are hollow or solid beads, or any combination/ratio of hollow and solid beads, wherein the beads comprise one or more material(s) selected from ceramic material(s); polymeric material(s); cermet material(s); metallic material(s); pigmented material(s); light-absorbing and/or light reflecting material(s); including any combination thereof, wherein said layer is covalently bound to said particles, wherein the photocatalytic layer comprises TiO 2  in the crystal form of anatase; and wherein the coating composition (paint) comprises less than 0.1 anatase particles derived/released from the micro-sized beads, determined as weight/weight of released anatase/total amount of anatase. The invention provides paint essentially without presence of unbound anatase crystals which is highly undesired, as it is believed that their presence has a negative influence on essential components of the paint, such as binder, pigment and/or additives and furthermore, anatase may cause eye, skin, and respiratory tract irritation.

Claim (Index 1):
A self-cleaning coating composition comprising a binder and micro-sized particles coated with a photocatalytic layer, wherein the micro-sized particles are hollow or solid beads, or any combination/ratio of hollow and solid beads, wherein the beads comprise one or more material(s) selected from the group consisting of ceramic material(s); polymeric material(s); cermet material(s); metallic material(s); pigmented material(s); light-absorbing and light reflecting material(s); and a combination thereof, wherein said photocatalytic layer is covalently bound to said particles after adsorbed water is evaporated from particle surfaces, wherein the photocatalytic layer comprises TiO 2  in the crystal form of anatase; and wherein the coating composition comprises less than 0.1 percent free anatase particles derived/released from the micro-sized beads, determined as weight/weight of released anatase/total amount of anatase.
