Industrial painting services apply paint to substrates for protection and/or decoration. They use several types of painting processes. Coil coating or roll coating is a continuous, high speed, roll-to-roll process for coating metal that will be fabricated into parts or finished products. In dip coating or immersion coating, parts are dipped or immersed into a bath or tank filled with paint. Dry lubricants are often painted onto the surfaces of machine parts, fittings, cams, springs, gears, cables, and elastomeric gaskets in order to reduce friction, corrosion, and wear. The most commonly used dry lubricants are molybdenum disulfide (MoS2 ) and polytetrafluoroethylene (PTFE). These compounds are often mixed together or combined with adhesion promoters. Powder coating is a finishing technology in which dry paint particles are charged electrostatically and then applied to a grounded part. Electrostatic attraction holds the particles in place until heat is added and the powder is cured. Web coating applies a layer of paint to the surface of a continuous sheet of material. Some industrial painting services specialize in the coating of new components or the recoating of damaged surfaces. Others perform general-purpose painting or specialize in architectural painting for the preservation or restoration of buildings and process plants.
