Structure and properties of compositions for protection of canning containers

Despite the broad range of materials for protection of canning containers, most lacquers used at present are produced on the basis of epoxyphenol oligomers. However, the diversity and complexity of the technological processes of fabricating modern types of canning containers, various sterilization regimes of canned products, high requirements to the terms of their storage compel researchers to search for ways to improve the properties of epoxyphenol compositions. Work is under way mainly in two directions: chemical modification of particular components of epoxyphenol compositions, mainly phenol-formaldehyde oligomers, and modification of epoxyphenol compositions by various additives.
