Contact allergy to epoxy hardeners.
BACKGROUND Diglycidylether of bisphenol A resin is the most important sensitizer in epoxy systems, but a minority of patients develop concomitant or solitary contact allergy to epoxy hardeners. At the Finnish Institute of Occupational Health, several in-house test substances of epoxy hardeners have been tested in a special epoxy compound patch test series. OBJECTIVES To analyse the frequency ...
متن کاملPreparation and Characterization of New Geopolymer-Epoxy Resin Hybrid Mortars
The preparation and characterization of metakaolin-based geopolymer mortars containing an organic epoxy resin are presented here for the first time. The specimens have been prepared by means of an innovative in situ co-reticulation process, in mild conditions, of commercial epoxy based organic resins and geopolymeric slurry. In this way, geopolymer based hybrid mortars characterized by a differ...
متن کاملOccupational contact dermatitis caused by 1,3-benzenedimethanamine, N-(2-phenylethyl) derivatives in hardeners for epoxy paints and coatings.
BACKGROUND Amines in epoxy hardeners are significant causes of occupational allergic contact dermatitis among workers who use epoxy resin systems. OBJECTIVES To describe a novel group of contact allergens: N-(2-phenylethyl) derivatives of the reactive amine 1,3-benzenedimethanamine (1,3-BDMA). METHODS We describe the clinical examinations and exposure of 6 patients with occupational contact...
متن کاملPreparation of antibacterial coating film using ZnO nanoparticles and epoxy resin
The production of antibacterial and antifungal nanocomposites is widely usedin pharmaceutical, health, food, packaging and medical industries. Meanwhile,the epoxy coating film is one of the most commonly used protective coatings inindustrial applications. In this work, ZnO nanoparticles were first synthesized atthree different concentrations. UV-Vis spectroscopy and dyna...
متن کاملPreparation and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid
The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...
