In sheet metal painting for various applications like Tractor, Automobile, most attractive coating is metallic paints and it is widely applied using 3 coats 2 bake or 3 coat 1 bake technology. Both options, results in high energy consumption, higher production throughput time & lower productivity in manufacturing process. During various brainstorming & sustainable initiatives, paint application process was identified for alternative thinking to reduce burden on environment & save energy. Various other industry benchmarking & field performance requirement studies helped us identify the critical to quality parameters. We worked jointly with supplier to develop mono-coat system without compromising the performance & aesthetical properties. This results in achieving better productivity, elimination of two paint layers, substantial reduction in volatile organic content, elimination of one baking cycle and energy saving. Metallic mono-coat formulated using strong polyurethane resins & latest technology pre-coated aluminum pigment for achieving metallic effect in finish. With new resin technology further, reduction of baking temperature is possible & reduce further energy consumption. The proposed technology is fully validated on component and ready. Proposed technology meets all stringent tractor industry specifications including chemical, fertilizer, resistance and comparable weather resistance to solid mono-coat currently being used.
