Patent ID: 8048965

Claim:
A method for extending a shelf life of vinyl ester resin or unsaturated polyester resin, comprising the step of enhancing an oxygen content of said vinyl ester resin or said unsaturated polyester resin; wherein the step of enhancing the oxygen content of said vinyl ester resin or said unsaturated polyester resin is accomplished by conducting a chemical reaction that produces oxygen in said vinyl ester resin or said unsaturated polyester resin by using a plurality of chemical substances; wherein a first vessel in which said chemical substances are deposited is placed in a second vessel in which said vinyl ester resin or said unsaturated polyester resin is stored, such that the oxygen produced from said chemical reaction is introduced into said vinyl ester resin or said unsaturated polyester resin by diffusion; wherein said chemical substances comprise calcium peroxide and methacrylic acid; wherein the ratio of said calcium peroxide to said methacrylic acid ranges from 1:2 to 1:0.001.
