Surface composition and method of application

Abstract

A surface composition for reducing degradation and fading of surfaces subjected to extended periods of submersion in an aqueous liquid includes 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 clear barrier layer provides structural protection against degradation from chemical attack and from fading due to UV exposure.

What is claimed is: 
     
         1 . A method of manufacturing a pool, the method comprising:
 applying a clear gelcoat liquid to a mold, wherein the gelcoat is a clear polyester gelcoat comprising one or more phthalate containing polyesters, vinyl containing polyesters or methyl methacrylate containing polyesters;   permitting the gelcoat to cure and subsequently applying a colored or decorative layer comprising inorganic or organic pigments and comprising one or more polyesters, vinyl esters or terephthalate based resins to the cured gelcoat;   applying fiberglass lamination to the colored or decorative layer; and   releasing a cured finished pool from the mold.   
     
     
         2 . The method according to  claim 1 , wherein the clear polyester gelcoat comprises a phthalate containing polyester. 
     
     
         3 . The method according to  claim 2 , wherein the phthalate containing polyester is derived from an isophthalic neopentyl glycol. 
     
     
         4 . The method according to  claim 3 , wherein the phthalate containing polyester is derived from greater than 70 mole % neopentyl glycol based on the total mole % of dihydroxy compounds in the polyester. 
     
     
         5 . The method according to  claim 1 , wherein the coloured or decorative layer comprises one or more epoxy vinyl esters, brominated epoxy vinyl esters, novolac epoxy vinyl ester resins or elastomer modified vinyl ester resins. 
     
     
         6 . The method according to  claim 5 , wherein the epoxy vinyl ester resin comprises a bisphenol-A epoxy vinyl ester resin. 
     
     
         7 . The method according to  claim 1 , wherein the coloured or decorative layer further comprises one or more decorative agents in the form of chips or particles. 
     
     
         8 . The method according to  claim 1 , wherein the clear gelcoat comprises one or more UV inhibitors, absorbers and/or stabilisers. 
     
     
         9 . The method according to  claim 1 , wherein the clear gelcoat comprises a triazine based UV absorber. 
     
     
         10 . The method according to  claim 1 , wherein the clear gelcoat comprises a hindered amine light stabiliser. 
     
     
         11 . The method according to  claim 1 , wherein the clear gelcoat comprises one or more metal promoters. 
     
     
         12 . The method according to  claim 11 , wherein the one or more metal promoters is selected from the group consisting of zinc octoate, potassium octoate, or cobalt octoate. 
     
     
         13 . The method according to  claim 1 , wherein the colored or decorative layer comprises one or more metal promoters.
