Function of Epoxol® 7-4

The activity of Epoxol® 7-4 as a plasticizer acid scavenger and reaction chemical intermediate is due to its oxirane content (7% minimum), an average of 4-1/2 groups per molecule. It is capable of reacting with 4-1/2 equivalents of mineral acid, halogen acid, or carboxylic acid. The stronger and more corrosive the acid, the more rapidly it is deactivated by Epoxol® 7-4. The epoxy groups in Epoxol® 7-4 open in the presence of acids and chemically combine to form neutral esters of the acid present.
(Epoxol® 7-4 and its reaction products with acids are neutral.)
