Types of coating in Pakistan

Understanding types of coating; the meaning of coating

Before you can understand types of coating, it is important to know the meaning of the word. The word coating means literally a thin layer or, when used as a verb, the application process of covering surfaces (usually referred to as substrates). Coating is used for changing the properties or enhancing the decorative appearance of an object as well as to create a protective barrier against deterioration. Known coating synonyms are:

  • covering
  • layer
  • glaze
  • varnish
  • paint
  • film
  • lacquers
  • finish
  • veneer

4 main types of coating resins

Industry standards define three types of coatings; metallic, organic and inorganic. However, most coatings contain a combination of organic, synthetic and inorganic materials, including solvents, pigments, fillers and extenders. These additives improve the application and curing process. What more defines the coating is the resin base. The most common resin types are:

  1. Epoxy
  2. Polyurethane
  3. Alyd
  4. Acrylic

With so many chemicals blends available, there is an engineered coating for almost every industrial and commercial application. That is why there are many different coating solutions available.

Functional and protective types of coating

Functional coatings may be applied to change the surface properties of the substrate, such as adhesion, waterproofing, corrosion resistance, or wear resistance. The segment protective coatings consists of coatings with protective and damage preventive properties. The hot weather in Pakistan asks for specific types of coating. Commonly used coatings in Pakistan are for example:

Protective types of coating on steel

Types of coating can be protective and decorative at the same time!

  • fire resistant/retardant coatings
  • intumescent coatings
  • anti fouling coatings
  • cooling coatings
  • corrosion protection coating
  • conforming coatings
  • weatherproof coatings

Especially fire retardant, intumescent and fireproof coatings have to meet strict regulations. Therefor, Islamabad (and Pakistan) businesses are by law required to use approved applicators for these coatings to ensure compliance with the standards of Pakistan legislation.

10 different types of coating methods (process)

Different regulations and technical requirements for each market and application dictate different types of coating. It is also important to choose the right type and method of coating as each type of coating method accomplishes a different goal and has its own appearance.

Here are 10 common coating methods in Pakistan:

  1. Powder coating (electrostatic spray deposition)
  2. Spray Painting
  3. Brush painting
  4. Roller coating
  5. Thermal spraying
  6. Dip Coating
  7. Hot dipping (Galvanizing)
  8. Electroplating
  9. Coil coating

Most coatings are applied during the manufacturing of a product. If you need any help to determine the best coating method for your project, do not hesitate to contact us. We are happy to help!

Growing coating industry in Pakistan

Powder coating is the biggest coating industry in Pakistan and consists of many colors and finishes, followed by conformal coating. The coating world is rapidly expanding, especially in Islamabad and Karachi with special purpose coating types. Pakistan’s market for coating has very big potential not only in terms of increase in local consumption but also in terms of trading. Worldwide the coatings industry is expected to grow up to $176.5 Billion in 2020, which will impact regional markets in Pakistan in terms of new trading and production opportunities.
