Abstract
Official abstract text for this publication.
A liquid coating composition is disclosed that is prepared from a reaction mixture comprising an amine component comprising (a) an amine component comprising a polyamine complexed with CO 2 and (b) a crosslinker, wherein the amine component is liquid at ambient conditions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing a coated substrate, comprising: spraying onto a substrate a liquid reaction mixture comprising: (a) an amine component liquid at ambient conditions comprising a polyamine complexed with CO 2 , and (b) a crosslinker, whereby the polyamine disassociates from the CO 2 upon spraying and is reactive with the crosslinker. 2. The method of claim 1 , wherein said polyamine comprises a hindered polyamine. 3. The method of claim 2 , wherein said hindered polyamine comprises an aliphatic, cycloaliphatic, or aromatic polyamine. 4. The method of claim 1 , wherein said crosslinker comprises at least two functional groups reactive with amines. 5. The method of claim 4 , wherein said functional groups comprise an isocyanate, oxirane, anhydride, aldehyde, ketone, beta-diketone, beta-ketoester, malonate, acrylate, and/or fumarate. 6. The method of claim 4 , wherein said functional groups comprise an isocyanate. 7. The method of claim 5 , wherein the crosslinker comprises a monofunctional isocyanate, oxirane, anhydride, aldehyde, ketone, beta-diketone, beta-ketoester, malonate, acrylate, and/or fumarate. 8. The method of claim 5 , wherein said crosslinker comprises an aliphatic, cycloaliphatic, and/or aromatic crosslinker. 9. The method of claim 1 , wherein said CO 2 dissociates from said polyamine upon spraying at ambient conditions. 10. The method of claim 1 , wherein said CO 2 dissociates from said polyamine upon spraying at an elevated temperature. 11. The method of claim 1 , wherein the liquid reaction mixture further comprises a catalyst or an accelerant. 12. The method of claim 1 , wherein the substrate comprises a metallic or non-metallic substrate.
