However, it is also known that, DGEBA epoxy resin, amine hardeners, dicarboxylic (phthalic) anhydride hardeners, and reactive epoxy diluents are all common causes of allergic contact dermatitis. And since all are health hazard causing organic pollutants, no remnants should be left in the composite, and must be decreased or avoided completely [73, 74]. 

Other examples of this phenomenon include residual crosslinking agents from partially cured duroplastics, formaldehyde from phenolic resin, amines in epoxy resins, and benzoyl peroxide from unsaturated polyesters. Section 5.3 in chapter Processing (Primary Forming) of Plastics into Structural Components addresses the nitrosamine in elastomers. 

The main obstacle to wide employment of organic compositions for impregnation purposes lies in selective adsorption of certain components by the pores of the surface of the impregnated materials. If this happens, the components are separated, leading to disturbance of the system s stoichiometry and to lack of curing. For example, when concrete is impregnated with epoxy resin/amine hardener mixture, the upper part of the concrete becomes impregnated with epoxy resin only, and the deeper parts with hardener.

A common modification which is performed commercially to selectively improve the performance is to react a glycidyl ether resin with an excess of amine groups to produce a resinous amine adduct hardener. These have advantages over unmodified versions in that they result in more convenient mixing ratios, are less dangerous to handle and can exhibit reduced moisture sensitivity.

Little information is available about the long term behavior of the filler substances when immersed in sea water and under irradiation. Bitumen is known to become brittle and crack below room temperature. As Furfurol(F) is a patented material, information about its composition and behavior was not available to the Group, and long term behavior is, in any case, difficult to predict. It is known to be a mixture of the following constituents epoxy resin, amine type solidifier, mineral filler, shale distillate and furfuryl alcohol [26]. An effective lifetime of SOO years is quoted in the White Book [1] for this material. 

Class I methyl MF resins are the most commonly used cross-linkers. Various types and amounts of amine can be used (164-166). Generally, less than the stoichiometric amount of amine is used. The lower the amine content, the lower the viscosity of the fully diluted systems. For any resin-amine combination, there is a minimum amoimt of amine required to give a stable dispersion at application viscosity, that is, to prevent macrophase separation. The viscosity is sensitive to amine content. The structiu-e of the amine affects application solids, stability, and cure rate. DMAE is widely used but N-alkylmorpholines and 2,2-dimethylaminopropanol permit faster curing. The amine also affects on wrinkling during curing (164). 

This technique has found the following applications in addition to those discussed in Sections 10.1 (resin cure studies on phenol urethane compositions) [65], 12.2 (photopolymer studies [66-68]), and 13.3 (phase transitions in PE) [66], Chapter 15 (viscoelastic and rheological properties), and Section 16.4 (heat deflection temperatures) epoxy resin-amine system [67], cured acrylate-terminated unsaturated copolymers [68], PE and PP foam [69], ethylene-propylene-diene terpolymers [70], natural rubbers [71, 72], polyester-based clear coat resins [73], polyvinyl esters and unsaturated polyester resins [74], polyimide-clay nanocomposites [75], polyether sulfone-styrene-acrylonitrile, PS-polymethyl methacrylate (PMMA) blends and PS-polytetrafluoroethylene PMMA copolymers [76], cyanate ester resin-carbon fibre composites [77], polycyanate epoxy resins [78], and styrenic copolymers [79].
