Coating process from A to Z

A coating is a substance that is applied to an object or surface. A coating can change the substrate’s property or appearance as well as protecting the substrate from wearing out. There are many different types of coatings due to the fact that they are suitable for different applications and have different properties. Some coatings are ideal for wood whereas others are more suitable for metal or plastic surfaces. When it comes to properties, the use of coating is prevail: floors need durable coatings such as epoxy or PU systems and stairs should be made anti slip.The basic manufacturing coating process is similar in most types of liquid paints. The main ingredients for coatings are:

  • Solvent/water;
  • Filler;
  • Pigment;
  • Binder;
  • Additives.

A major consideration for most coating processes is that the coating is to be applied at a controlled thickness, and a number of different processes are in use to achieve this control, ranging from a simple brush for painting a wall, to some very expensive machinery applying coatings in the electronics industry.

The great variety of coatings and processes

There are many different types of coating to identify. For instance there is anti corrosion coating, anti graffiti coating, anti fouling coating, roof coating, protective coating and optical coating. At coatings.co.in we will inform you about all the coating types and possibilities. The possibilities are infinite. For instance, you can use a special coating for all sorts of materials like; wood, concrete, glass, metals and aluminum.

Industrial coating process and methods

Coatings can be applied in many different ways depending on the type of product and surface. For example most polyurethane and epoxy coatings consist of two components, which means that the application includes mixing the components. Therefore, a one pot system applications can be simpler. The coating process for industrial and decorative coatings are very different from each other. Most home decorators apply paints and coatings with either roller or brush. Also spray solutions are available. Other application methods such as powder coating are possible to realise at home, however, they do require more knowledge on the coating process and equipment.

Dip coating, industrial coating process in action

Dip coating is a common industrial coating process.

Industrial applications, for their part, are often more complicated and they must be time efficient. Therefore, depending on the product, the industrial coating process is often automated. The process can be carried out using:

  • Electrostatic spray (powder coating)
  • Roller/brush (most liquid paints, also consumer products)
  • Thermal spray
  • Dipping applications

Every coating process includes cleaning the surface, applying the product and curing. In general, the surface should be dust/dirt and grease free. The surface can further be prepared by sanding and applying a sealer or primer, depending on the recommendations. After applying the first layer, bringing on mid or topcoat follows. Sometimes other layers are needed for ideally completing the coating process. Last but not least, curing refers to letting the coating harden and dry. This can be done with several methods such as UV curing, high temperature curing (oven for powder coatings) or naturally by giving the surface time to dry. Also the curing process is dependent on the type of paint.
