Application

The uniqueness of D.E.R. 332 epoxy resin is reflected in its maximum epoxide equivalent weight of 178. Because of its high purity and lack of polymer factions, samples embedded using D.E.R. 322 have uniform performance, exceptionally low viscosity and color; and improved elevated temperature properties.

Caution

Crystallizes very slowly at room-temperature; can be melted by heating up to 50-55 °C
