Electrochemical Characterizations of Epoxy Coatings Embedded by Modified Calcium Carbonate Particles

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...

Photo-oxidative Stability of a Series of Red Acrylic Paints

Photo-oxidative stability of a series of most common red acrylic paints has been investigated. The paints in question were carmine, quinacridone scarlet, alizarin crimson, brilliant red, vermilion and cadmium red hue. Structural changes, discoloration and weight loss of paints film subjected to UV irradiation in an accelerated ageing chamber were measured using FT-IR spectroscopy, colorimetry a...

Hplc Determination of Free Acrylic Acid and Monomers in Polyacrylates

Acrylic polymers have broad applications in the manufacture of paints and paper coatings, emulsion adhesives, plastics, lighting, glass replacements, personal care products and even dental fillings. However, acrylic acid and some acrylate oligomers and monomers adversely affect human health as eye and skin irritants. Exposure to monomers occurs primarily in the workplace via inhalation and derm...

Time to Ban Lead in Industrial Paints and Coatings

In the U.S. and most high-income countries, regulations already restrict the use of lead paint for residential applications. However, few countries have enacted comprehensive bans on the use of lead additives in all paints. In 2009, more than 120 countries at the UN International Conference on Chemicals Management (ICCM) voted to phase-out all lead paints (1). Since then, a few countries includ...
