Coil coating is a continuous and automated process that applies an organic coating substance to a rolled metal strip. Cleaning and chemical pre-treatment of the metal surface on one or both sides, single or repeated applications of liquid paints or coating powders, which are then cured or laminated with plastic sheets before manufacture into an end product are all part of the process. Cleaning, pretreating, pre-priming, pre-painting, and coating flat metal coils or sheets of steel or aluminum in a continuous process before subsequent stages of industrial manufacturing are used in coil coating. At 700 feet per minute, steel or aluminum substrates are provided in coil form. A flat sheet enables for mechanical cleaning as well as good control of coating weights for pretreatment and paint depending on the equipment and paint system being used. The coil coating process comprises a back coat, top coat, and primers that come in a variety of colors and finishes and may be applied to steel or aluminum coils using rollers.
Uncoiling of bare material, coil splicing with stack accumulation, metal degreasing, cleaning, rinsing with a chemical pretreatment, drying the strip, applying primer on one or both sides, curing (15 to 60 seconds), cooling the strip, top coating on one or both sides, second curing, cooling to room temperature, and finally rewinding of t Coil coating creates long-lasting surfaces with eye-catching topcoats. When compared to alternative substrates and coil coating choices, they are both cost-effective and environmentally benign.
Building uses for coil coatings include wall cladding, roofing, ornamental elements, and lighting fixtures. Sheet and panel applications for containers, caravan and mobile home sidings and interiors, van and trailer bodies, insulated boxes, road and railway coaches Refrigerators, washing machines, dishwashers, microwaves, heating, ventilation, and air-conditioning equipment are examples of their uses in the appliance and general industries. They are also utilized in film lamination for applications that need a high specular reflection, such as fluorescent light fixtures, solar tubes, and reflectors. Steel and aluminum are the primary application sectors for coil coatings. Increasing steel and aluminum demand in the construction and transportation industries is projected to drive the coil coatings market, while residential development is a more recent industry to be addressed.
