Electronics-grade dicyandiamide hardener for epoxy resins Application IsoQure® DCD 100 ETS is a high-purity latent epoxy resin hardener which provides (in contrary to aliphatic or aromatic amines) an almost unlimited shelf life of the finished epoxy resin compound. At temperatures starting at about 180°C, IsoQure® DCD 100 ETS reacts

of specific epoxy resin adhesives are given. 1 Introduction With the advent and use of room-temperature-cure epoxy resin adhesives for the repair of glass artifacts, many difficulties in bonding glass have been resolved [1]. The inherent tendency for epoxy resin adhesives to yellow with time has precluded their wider acceptance in conservation.

It is commonly known that dicyandiamide (dicy), as a curing agent for epoxy resins, will provide one part formulations with extended room temperature shelf lives. The cured properties of these formulations are usually quite acceptable for many applications. However, a significant drawback to a dicy cure is that it must be accomplished above 170°C.
