Jigs should be clean in order to maintain good earthing. To avoidcontamination, when using different colors, thorough cleaning of the application andrecovery systems must be carried out between each color. Care should be taken in keepingdifferent colors and types of powders well segregated.The total curing time of the film is dependent on several factors like material substrate,thickness & mass of the material and shape of the material.The effective curing time commences when the object has reached the recommendedtemperature.Storage & PackingStorage Store in closed, cool room (below 30C) in dry condition and in the original packing.Exposure to direct sunlight, heat and high humidity should be avoided. For best results, the stack height should not exceed three cartons. Partly used bags must be tightly closed after each removal and stored carefully insidethe carton in a cool dry storage room. For best performance use within six months.Packing Standard pack size is 10
