<p>Accordingly, the invention described herein relates to a low VOC epoxy based coating utilizing the following essential components: 1. An epoxy functional resin component where the average epoxide functionality is >1. 2. An aliphatic amine or aliphatic blocked amine functional component where the amine functionality is >1. This includes polyamidoamines, polyamines, ketimines and aldimines. 3. An acetoacetonate functional oligomer where the molecular weight is < 1000 and the acetoacetonate functionality is >1. 4. Optionally other components that typically constitute a complete coatings system such as pigments, catalysts, additives, plasticizers, etc. This is typically a three-package system however, with modification, it can become a two-package system.</p> |
