  • Publication number: 20120328811
    Abstract: An epoxy resin composition having a curing component and an epoxy component is disclosed. The curing component includes an amount of about 8% to about 70% by weight of the composition of a primary curing agent and about 0.001% to about 5% by weight of the composition of a secondary curing agent. The epoxy composition also includes about 30% to about 92% by weight of the composition of the epoxy component. A number of equivalents of reactive curative groups in the curing component is from about 0.50 to 0.98 times the number of epoxide equivalents present in the epoxy component. An epoxy product formed from the epoxy resin composition is also disclosed.
