Abstract
Official abstract text for this publication.
Disclosed herein are methods for pasteurizing architectural coating compositions using heat, radiation or other energy sources without additionally polymerizing the compositions and storing same.
First claim
Opening claim text (preview).
We claim: 1. A method for pasteurizing a paint or stain composition comprising the steps of (i) preparing the paint or stain composition, wherein the paint or stain composition comprises latex particles that when applied to a substrate form a paint film; (ii) treating the paint or stain composition with a gamma radiation, wherein an amount of applied gamma radiation is less than about 15 kilograys without further polymerizing the paint or stain composition; and (iii) storing the treated paint or stain composition in containers. 2. The method of claim 1 , wherein step (iii) comprises storing the pasteurized paint or stain composition at temperatures that discourages or inhibits growth of biological agents. 3. The method of claim 2 , wherein said temperatures are temperatures below ambient temperature. 4. The method of claim 1 , wherein the amount of applied gamma radiation ranges from about 3 kilograys to about 15 kilograys. 5. The method of claim 1 , wherein the amount of applied gamma radiation ranges from about 5 kilograys to about 10 kilograys. 6. The method of claim 1 , wherein the amount of applied gamma radiation ranges from about 3 kilograys to about 5 kilograys.
