Abstract

This article introduces effects of acrylic/melamine ratio on mechanical properties, chemical stability, thermal resistance,… of baking acrylic- melamine varnish. Infrared spectroscopy (FT-IR), Thermal gravimetric analysis (TGA), FESEM,... were used to examine the investigation’s results. Through testing mechanical properties and through- drying temprature of coating, acrylic / melamine ratio is 35/15 and drying temperature of 140^oC, in 60 minutes are determined. Infrared spectroscopy (IR) shows curing reaction between acrylic and melamine resin. In addition, article also introduces testing results in lubricant, HCl acid 5%, A95 gasoline for 240 hours and thermal stability of acrylic- melamine varnish. Results of TGA have shown that thermal decomposition of varnish coatings depend on ratios of acrylic/melamine resin. Acrylic- melamine coating is capable of being used to protect metal parts in some chemical conditions and the coating can be used for cars’ fuel tank or motors’ fuel tank,...
