Title
(EN) SELF-HEALING COATING COMPOSITIONS
(FR) COMPOSITIONS DE REVÊTEMENT AUTO-RÉPARANT
Abstract
(EN)
Self-healing coating compositions are provided. In embodiments, such a composition comprises a liquid medium and a network of hollow capsules extending through the liquid medium in three dimensions, the network comprising a plurality of chains formed from the hollow capsules, aggregates of the hollow capsules, or both, wherein exterior surfaces of the hollow capsules of the plurality of chains define a plurality of channels filled with the liquid medium, and wherein the coating composition has a room temperature viscosity greater than that of the liquid medium. Coated surfaces formed from the compositions and methods of protecting surfaces using the compositions are also provided.
(FR)
L'invention concerne des compositions de revêtement auto-réparant. Selon certains modes de réalisation, une telle composition comprend un milieu liquide et un réseau de capsules creuses s'étendant à travers le milieu liquide dans trois dimensions, le réseau comprenant une pluralité de chaînes formées par les capsules creuses, des agrégats des capsules creuses, ou les deux, les surfaces extérieures des capsules creuses de la pluralité de chaînes définissant une pluralité de canaux remplis du milieu liquide, et la composition de revêtement ayant une viscosité à température ambiante supérieure à celle du milieu liquide. L'invention concerne en outre des surfaces revêtues formées avec les compositions et des procédés de protection de surfaces mettant en œuvre les compositions.
