Curing Agents Hardeners

The mechanisms of radiation damage and effects of hardeners were studied recently by pulse radiolysis [89], The epoxy resins require a relatively large amount of curing agents (hardeners), most of them are aromatic and aliphatic amines such as diamino diphenyl methane or triethylene tetramine. On the basis of the emission spectra and kinetic behavior of excited states observed, the radiation resistance of aromatic and aliphatic amine curing epoxy resin was explained by internal radiation protection effects due to energy transfer. [Pg.76]

Leecure B. [Leqroxy Plastics] Boron ttifluoride-based epoxy curing agents/ hardeners. [Pg.206]

The epoxy group (oxirane ring) can react with both nucleophilic and electrophilic reagents. The most typical example of a step-growth polymerization of epoxy monomers is the reaction with amines, which are the most commonly curing agents/hardeners used to build up epoxy networks. The reactions shown in Scheme 28.1 take place in this case. [Pg.520]

Epoxy adhesives are widely used in electronics assembly and packaging. They are formed by polymerizing epoxy resins having one or more terminal glycidyl ether (epoxy) groups with a variety of curing agents, hardeners, or catalysts. [Pg.77]
