In this paper, electrochemical behavior of epoxy paints embedded by modified calcium carbonate particles was investigated during exposure to 3.5 wt% NaCl solution. The precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) particles were utilized as inexpensive filler for epoxy paints. Electrochemical impedance spectroscopy (EIS), polarization tests and pin-on-disk method w...

Epoxy resin systems have been associated with occupational asthma in several case reports, but medical publications contain little on the potential adverse respiratory effects of these chemicals in exposed worker populations. To further evaluate the association of workplace exposure to epoxy paints and respiratory dysfunction, the cross workshift changes in pulmonary function and symptoms of 32...

Epoxy resins are used widely in industry because of their strong adhesive properties, chemical resistance, mechanical toughness and high electrical insulation. Consequently they are often found in adhesives, stabilizers, sealants, varnishes and paints. Epoxy resins consist of bridged diepoxide oligomers of increasing molecular weight and there are various types corresponding to different molecu...

ing operations involvig the use of a bisphenol-A diglycidyl ether tye of epoxy resin. ln a faciity producig miltaiy aircraft, the use of an epoxy prier did not result in detectable epoxide levels, and the authors surmised that the epoxy-amine curig reaction had probably . consumed most of the epoxide group. Epoxide levels of 2-12 J.Eq/m3 epode functional group were recorded durig the painting o...

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...

BACKGROUND We present an unusual case of subcutaneous granulomas that also highlights the importance of assessing possible associations between exposure and symptoms early in the diagnostic approach to prevent further adverse health effects. Granulomas of the skin are seen in association with several diseases and after foreign body penetration of soft tissue, but have not been described after c...
