Epoxy value

[1] This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent.

[2] The epoxide equivalent weight is usually measured first and done by titration.

The standard test method is ASTM D1652 though this has been modified by certain states of the USA.

[5] Polyoxypropylene diglycidyl ether, a reactive diluent with the trade name of Diluent F, has an average molecular weight of 1000 and a functionality of 2 so the EEW is 1000/2 = 500.

[6] There are methods using instruments that do not use traditional titration techniques to determine epoxide equivalent weights.
