Curing agents acidic

The cycloahphatic products are generally Hquids of lower viscosity than the standard glycidyl ether resins. The peroxidized resins contain no chlorine and low ash content and their ring-contained oxirane group (cyclohexene oxide type) reacts more readily with acidic curing agents than the bisphenol A-derived epoxy resins. [Pg.364]

The type of epoxy group and its location within the molecule influence reactivity. Some epoxy resin structures prefer to react with acid curing agents, and others with basic curing agents. Certain epoxy structures are extremely reactive with specific catalysts, and others are virtually inactive. Several types of epoxy resins are reactive with almost all classes of curing agents. [Pg.53]

Amines. Tertiary amines R3N are catalysts that open the epoxy ring and thus catalyze the polymerization reaction. They may be used with hydroxyl-containing molecules to catalyze homopolymeiization (Fig. 3.26), but more often they are used to catalyze copolymerization of epoxy resins with amine or acid curing agents. Several more specialized amines are also mentioned as catalysts (Fig. 3.27). [Pg.156]

Catalysts. The choice of a catalyst and of its amoimt is important. As discussed in previous sections, some tertiary amine catalysts can play multiple roles in the curing reaction. Anhydride cure in particular is highly sensitive to catalyst amount. Nucleophilic catalysts, used with acidic curing agents such as... [Pg.2728]

The reactions of epoxy resins with the acid curing agents are more complex than those with the amine curing agents and are somewhat less well understood [77,78]. The reactions may be brought about with or without catalysts. The uncatalyzed reaction, in simplified form, may be represented by... [Pg.410]

Postcured silicates Soluble silicates are combined with zinc dust to form very hard rocklike films that are further stabilized by reacting them with an acidic curing agent. [Pg.613]
