| 20090176932 | Halogen containing epoxy compositions and their preparation - One aspect of the current invention is a halogen containing epoxy composition and a method of producing the same. A functional halogen group, fluorine in one case, is incorporated into an epoxy coating by using a functionalized amine curing agent in small amounts. Functionalized amine curing agents are cheaper and easier to produce from small amine precursors when compared to the cost and complexity of functionalizing bulky epoxy resins. Amine curing agents are incorporated into a cured epoxy network. However, many functional groups will affect the reactivity of the curing reaction due to electronegativity effects. By using small amounts of functionalized amines with a large amount of non-functionalized agent, the effect is small and in the case of migration, it can be advantageous for tribological, mechanical and other properties of epoxies and epoxy-containing materials. Additionally, in stratified coatings, it is advantageous to use smaller functionalized amine molecules that can migrate more quickly into the composition before the composition becomes fully cured. | 07-09-2009 |
