Beschreibung
Zusammenfassung:	UV curable coating compositions and methods for applying such compositions to surfaces to provide abrasion resistance and/or structural rigidity thereto. The UV curable compositions of the present invention include at least one curable (meth)acrylate, at least one photoinitiator which absorbs only in the UV range of the electromagnetic spectrum, and an inorganic filler, at least a portion of which having a particle size in the range of 1 to 1,000 nm. The compositions may further comprise a reactive diluent. L'invention concerne des compositions de revêtement durcissables par rayonnement UV et des procédés d'application desdites compositions sur des surfaces pour conférer à celles-ci une résistance à l'abrasion et/ou une rigidité structurale. Lesdites compositions de revêtement durcissables par rayonnement UV comprennent : au moins un (méth)acrylate durcissable ; au moins un photoinitiateur qui absorbe seulement dans la plage UV du spectre électromagnétique ; et une charge inorganique, dont au moins une partie présente une taille particulaire située dans la plage comprise entre 1 et 1000 nm. Les compositions de l'invention peuvent comprendre en outre un diluant réactif.
