  • Ultraviolet curable epoxidized alkyds
    Patent number: 5612445
    Abstract: The epoxidation of alkyds containing anhydrides or diacids with cycloaliphatic unsaturation results in epoxy resins which cure rapidly in UV light to produce uniform films without the use of flow modifiers. The fatty acid portion of the alkyd functions as an internal plasticizer. Crosslinking occurs through oxirane rings in both the anhydride and fatty acid moieties of the alkyd to produce hard, but not brittle films. Excellent water resistance is obtained without thermal post curing.
