Amino Terminated Unsaturated Polyamides and Their Application as Epoxy Resin Hardener
Polymerization of β-phenyl glutaconic diethyl ester (GE) with various diamines (DA) at 1:2 molar ratios in 1,4dioxane solvent was carried out at reflux temperature. The resultant amino terminated unsaturated oligomers (ATUP) were characterized by elemental analysis, number of terminal amino groups, IR spectral studies, number average molecular weight estimated by non-aqueous conductometric titr...
متن کاملOccupational contact allergy to the epoxy resin hardener 2-methylpentane-1,5-diamine.
A 63-year-old painter and varnisher presented with a 4-year history of work-related contact dermatitis affecting the dorsal surfaces of his hands, forearms, and face. He reported itching, burning and oozing when he occupationally handled epoxy resin systems. Patch testing was performed by the use of small Finn Chambers® on Scanpor® tape (SmartPractice Europe, Reinbek, Germany) with the baseline...
متن کاملOccupational Allergic Dermatitis Induced by an Epoxy Hardener Alkylamine
Epoxy resins have been widely used in commercial applications, and their adverse health effects have been mostly reported in occupational settings. The most frequent adverse effects are irritation or allergic mechanisms involving the dermal and respiratory systems. Sensitization is usually caused by low molecular weight or short-chain compounds. We report here two workers exposed to an epoxy re...
متن کاملCellulose whisker/epoxy resin nanocomposites.
New nanocomposites composed of cellulose nanofibers or "whiskers" and an epoxy resin were prepared. Cellulose whiskers with aspect ratios of approximately 10 and approximately 84 were isolated from cotton and sea animals called tunicates, respectively. Suspensions of these whiskers in dimethylformamide were combined with an oligomeric difunctional diglycidyl ether of bisphenol A with an epoxide...
متن کاملAssessment of cross-reactivity of new less sensitizing epoxy resin monomers in epoxy resin-allergic individuals.
BACKGROUND Measures to prevent occupational exposure to epoxy resins, including education, medical examination, and voluntary agreements between employers and workers, have not been effective enough to protect against skin sensitization. Therefore, alternatives to the major epoxy resin haptens that have been found to be less sensitizing in the local lymph node assay have been developed. OBJEC...
