Abstract
Official abstract text for this publication.
A curing agent for curing an epoxy resin comprises a fluorinated central moiety covalently bonded to first and second imide-amine moieties, the first and second imide-amine moieties include amine terminal functional groups, wherein the amine functional groups of the curing agent, when applied to the epoxy resin, take part in curing reactions with ring molecules of the epoxy resin.
First claim
Opening claim text (preview).
What is claimed is: 1. A curing agent composition for curing an epoxy resin comprising: first and second imide-amine moieties which each include amine terminal functional groups, and a fluorinated central moiety covalently bonded to the first and second imide-amine moieties, wherein the amine functional groups of the curing agent, when applied to the epoxy resin, take part in curing reactions with ring molecules of the epoxy resin, wherein the curing agent has a molecular weight of less than 2000 grams per mole, and wherein the curing agent has the following formula: 2. A cured epoxy matrix comprising: an epoxy resin matrix; and a curing agent composition cross-linked with the epoxy resin, the curing agent including first and second imide-amine moieties which each include amine terminal functional groups and a fluorinated central moiety covalently bonded to the first and second imide-amine moieties, wherein the amine functional groups of the curing agent take part in curing reactions with ring molecules of the epoxy resin matrix, wherein the curing agent has the following formula: 3. The cured epoxy matrix of claim 2 , wherein the curing agent is homogenously cross-linked with the epoxy resin throughout the matrix. 4. The cured epoxy matrix of claim 2 , wherein the curing agent has a molecular weight of less than 2000 grams per mole. 5. A curing agent composition for curing an epoxy resin comprising: first and second imide-amine moieties which each include amine terminal functional groups, and a fluorinated central moiety covalently bonded to the first and second imide-amine moieties, wherein the amine functional groups of the curing agent, when applied to the epoxy resin, take part in curing reactions with ring molecules of the epoxy resin, wherein the curing agent has a molecular weight of less than 2000 grams per mole, and wherein the curing agent has the following formula: 6. A cured epoxy matrix comprising: an epoxy resin matrix; and a curing agent composition cross-linked with the epoxy resin, the curing agent including first and second imide-amine moieties which each include amine terminal functional groups and a fluorinated central moiety covalently bonded to the first and second imide-amine moieties, wherein the amine functional groups of the curing agent take part in curing reactions with ring molecules of the epoxy resin matrix, wherein the curing agent has the following formula: 7. The cured epoxy matrix of claim 6 , wherein the curing agent is homogenously cross-linked with the epoxy resin throughout the matrix.
