Surface composition and method of application

摘要

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 hydrolyzing or oxidizing 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.

主权项

1. A method of manufacturing a surface composition for reducing degradation and fading of surfaces subjected to extended periods of submersion in an aqueous liquid, the method comprising
applying a clear barrier layer to a mould, permitting the clear barrier layer to cure and subsequently applying a colored under layer to the cured clear barrier layer; wherein the clear barrier layer is in use, disposed atop the colored under layer and in contact with the aqueous liquid, whereby the clear barrier layer protects the structure and appearance of the colored under layer, wherein-the clear barrier layer comprises a clear polyester gelcoat, and wherein the clear polyester gelcoat comprises one or more phthalate containing polyesters, vinyl containing polyesters or methyl methacrylate containing polyesters, and wherein the colored under layer comprises one or more polyesters, vinyl esters or terephthalate based resins, and wherein the colored under layer is free of particles and chips.
