Sensitizing Structure in Epoxy Resin
Journal of Investigative Dermatology, 1957 An instance of glue dermatitis was traced to epoxy resin. The hardener used was phthalic anhydride. Samples were obtained from the manufacturer (Ciba) in order to ascertain the sensitizing component. It was recommended that patch test be applied in a one per cent concentration in olive oil. The formula and results of testing appear in the Table.

Toughening of epoxy resins [PDF]
Designed Monomers and Polymers, 2006 Epoxy resins constitute an important class of thermosets which are used extensively in the field of composites, adhesives surface coatings, etc. They are of aliphatic, cycloaliphatic or aromatic backbones. Epoxy resins based on bisphenol A are commercially available and they have good thermal and mechanical properties.

Preliminary Study for Transparentization of SLS Parts by Resin Infiltration [PDF]
, 2004 Since opacity of SLS processed parts are derived from random reflection and refraction at boundaries of refractive indices between the air and plastic, infiltration of resin that shares the same index with the plastic can increase transparency of the ...

Metal (2) 4,4',4",4'" phthalocyanine tetraamines as curing agents for epoxy resins [PDF]
, 1985 Metal, preferably divalent copper, cobalt or nickel, phthalocyanine tetraamines are used as curing agents for epoxides. The resulting copolymers have high thermal and chemical resistance and are homogeneous. They are useful as binders for laminates, e.g.,

Thermochemical tests on resins: Char resistance of selected phenolic cured epoxides [PDF]
Curing epoxy resins with novalac phenolic resins is a feasible approach for increasing intact char of the resin system. Char yields above 40% at 700 C were achieved with epoxy novalac (DEN 438)/novalac phenolic (BRWE 5833) resin systems with or without ...
