Results e discussions Consumption analysis in accordance with the studies of an important resin producer Energy saving It is estimated a reduction of 5 -10% of the energy costs each 10 ° C decreasing of curing temperature This value is equal to 2 €/hour each 10 ° C decreasing (or 4000 €/year, the value is influenced by the type of oven used) Optimization of production line Increasing of line production speed Increasing of line production capacity Optimization of coating processes - New EVO+ product line

Conclusions • • The aesthetic quality is better even at low thicknesses Possibility to produce EVO+ in all colors The heating gradient sensitivity is less than standard products The EVO+ corrosion resistance is higher than standard products The accelerated weathering test UV-B 313 nm are similar to standard polyesters Decreasing of consumption and environmental impact The productive efficiency is higher than standard products Optimization of coating processes - New EVO+ product line
