Abstract

Using electrostatic spray coating technique, POLYPROPYLENE (EPD 60r) was applied an carbon steel substrates at room temperature. In order to obtain a uniform coating, steel substrates with powder coating were heated in a vacuum oven at various temperatures up to 250°C for various periods of time up to 45 min and a pressure of 200mb. The coating produced had thickness of around 470 microns. In order to modify the chemical structure of this polymer, the powder coatings containing various weight percentages of maleic (anhydride (MA) and a peroxide (TBHP or DCP) were also applied on to the steel substrates under the above conditions. ADHESION strength, were resistance, and ductility of polymer coatings produced were assessed using ASTM standard methods. Results obtained revealed that the polymer coating containing 5 wt%. MA and 0.1 wt%. TBHP had the best mechanical properties. Adhesive strength and were resistance of this coating were 14.3kgf and 250.3 cm, at 6 kgf, respectively, under the applied load of 6kg. Results obtained from DSC thermographs IR spectroscopy also proved the chemical bond formation (grafting) between the polymer and M.A. the mechanical properties of coating an steel substrate stem from such grafting.
