Industrial Coatings

Industrial coatings are thin, film coatings that are applied to materials to: add color to them, to improve their appearance, to provide corrosion and wear resistance, and to improve the thermal and electrical characteristics of the material. There are many different internal components and outer parts that that are used in industry that need to have an industrial coating on them to protect them.

There are many types of materials that can be coated such as stainless steel, leather, glass, ceramic, wood, fiber, plastic, and metals, etc. The coating can generally vary in thickness from a few microns to a few millimeters. There are also many types of coatings that can be applied such as: rubber, aluminum, copper, silver, gold, acrylic, boron nitride, titanium nitride, ceramic, epoxy, furan, graphite, plastic, latex, nylon, phenolic resins, plastisol, polyurethane, teflon, silicone, tin, chrome, wax, zinc, and vinyl, etc. Some items that commonly use industrial coating processes include aluminum beverage cans, automobiles, and electrical wiring.

Coatings are combined with various types of resins such as: furan, alkyd resins, epoxies, and thermosetting resins, etc. These substances form a thin coat on the surface of the material. Pigments that are made of titanium dioxide are added to give different colors to the coating. Compounds such as: calcium carbonate, talc, silicones, mica, etc. are often added as fillers and help maintain the sheen, viscosity and consistency of the coating.

Industrial coatings can be applied as: films and laminates, aerosols, liquids, powders, solids, pastes, and solvents-based, etc. The coatings may have different types of carriers such as: volatile organic compounds, glycol, alcohols, ethers and water-based carriers. There are many different processes used to apply the coatings such as: dip coating, rollers, brushes, sponges, screens, sprays, spinning, and electro-coatings, etc.

You need to make sure that the items you are going to coat are as clean and as smooth as you can get them. Different pre-coating techniques like sand blasting, rinsing in chemical baths, etc. are used along with emery polishing and etching to improve the surface adhesion qualities of the material. The cost of the coating process and the end-use of the items generally determine the method of coating and the materials that are used.
