Title (EN) OPTICAL COATING COMPOSITION
(FR) COMPOSITION DE REVETEMENT OPTIQUE
Abstract: front page image
(EN)Coating compositions yielding cured coatings that exhibit excellent abrasion- resistance and hardness for use on polymeric substrates such as the front side of optical lenses, in a manner that meets or exceeds the stringent requirements for such use. The compositions include a monomeric organofunctional silane, and colloidal silica present in an amount sufficient to improve abrasion resistance as compared to a composition lacking the colloidal silica.
(FR)La présente invention concerne des compositions de revêtement produisant des revêtements durcis qui présente d'excellentes résistance à l'abrasion et dureté pour utilisation sur des substrats polymères tels que la face avant de lentilles optiques, d'une manière qui satisfait à ou dépasse les exigences strictes pour une telle utilisation. Les compositions comprennent un silane organofonctionnel monomère, et une silice colloïdale présente en une quantité suffisante pour améliorer la résistance à l'abrasion comparée à une composition ne comprenant pas de silice colloïdale.
