Learn the meaning of coating before the coating types
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.
Coating types; industrial definitions
Each coating consists of its own mix with sometimes two or more resins, a special curing agent, pigment additives and solvents. This results in largely different properties for each coating. That is why there are many different coating solutions available.
Industry standards define three types of coatings;
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.
Epoxy, polyurethane and other resins
When we talk about different coating types we are basically talking about different components. The purpose of the coating and its properties depend on the type of resin in the component blend. The most common resin types are: Epoxy, Polyurethane, Alkyd, Acrylic
Depending on which resin was used, the coating may be applied to provide:
- Corrosion resistance
- Sealing & Waterproofing electronic circuit boards
- Fire & heat resistance
- Improved appearance (Aesthetics)
- Protection against wear, tear, pitting and general deterioration
- Self healing, self cleaning properties
- Chemical resistance
- Non stick adhesion properties
Especially fire retardant, intumescent and fireproof coatings have to meet strict regulations. Therefor, Taipei (and Taiwan) businesses are by law required to use approved applicators to ensure regulatory compliance with Taiwan standards.
10 most common coating methods in Taiwan

- Spray Painting
- Brush painting
- Roller coating
- Thermal spraying
- Dip Coating
- Hot dipping (Galvanizing)
- Coil coating
- Plasma spraying
The best type of coating for your project
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.

Growing segments in Taiwan
Marine paints, Army paints and traffic paints are a few examples of special purpose coatings. The coating world is rapidly expanding, especially in Taipei with special purpose coating types.
