CA 2752392

There is provided a surface composition for reducing degradation and fading of surfaces subjected to extended periods of submersion in an aqueous liquid. The surface composition comprises at least one clear barrier layer and at least one under layer, wherein the clear barrier layer is in use, disposed atop the under layer and in contact with the aqueous liquid whereby the clear barrier layer protects the structure and appearance of the under layer. The surface composition is particularly useful in applications where the surface is subjected to extended periods of submersion in liquids containing hydrolysing or oxidising agents, exposure to ultra violet radiation, or combinations thereof, whereby the clear barrier layer provides structural protection against degradation from chemical attack and from fading due to UV exposure. There is also provided a method of manufacturing a boat or other watercraft surface composition. There is further provided a use of a surface composition in the manufacture of a boat or other watercraft. There is yet further provided a boat or other watercraft manufactured from the inventive surface composition.

L'invention porte sur une composition de surface pour réduire la dégradation et la décoloration de surfaces soumises à des périodes prolongées d'immersion dans un liquide aqueux. La composition de surface comprend au moins une couche barrière transparente et au moins une sous-couche, la couche barrière transparente étant, lors de l'utilisation, disposée au-dessus de la sous-couche et en contact avec le liquide aqueux, gla couche barrière transparente protégeant la structure et l'aspect de la sous-couche. La composition de surface est particulièrement utile dans des applications dans lesquelles la surface est soumise à des périodes prolongées d'immersion dans des liquides contenant des agents hydrolysants ou oxydants, d'exposition à un rayonnement ultraviolet ou des combinaisons de ceux-ci, la couche barrière transparente offrant une protection structurale contre une dégradation due à une attaque chimique et contre une décoloration due à une exposition aux ultraviolets. L'invention porte également sur un procédé de fabrication d'une composition de surface pour bateau ou autre embarcation. L'invention porte en outre sur une utilisation d'une composition de surface dans la fabrication d'un bateau ou autre embarcation. L'invention porte en outre sur un bateau ou autre embarcation fabriquée à partir de la composition de surface de l'invention.
