Polyepoxy reactive diluents

Diepoxy and polyepoxy reactive diluents. Diepoxy or polyepoxy reactive diluents are incorporated in order to preserve physical properties at elevated temperatures. These diluents will not reduce system functionality and in some cases will result in an increase in system cross-linking density. They can be used in higher concentrations than can the monoepoxy diluents to obtain the desired reduction in viscosity. Some examples are shown in Figure 2.13.

The commercial flexibilizing reactive diluents are predominantly glycidyl derivatives of glycols, dimerized acids, or reaction products of dicarboxylic acids with epoxy resins. The properties of certain polyepoxy diluents are summarized in Table 8.3. Some of, but not all, these materials provide good reactivity with aliphatic primary amines at room temperature.
