Professional guidance on how to buy powder coating powder for industrial use
Powder coating is not just the coating used to hot-up vehicles. It is a highly protective coating method that is used to protect substrates from corrosion, chemicals, weather, and physical damage while providing an attractive drip-and-sag-free finish. Powder coating is also a cost effective coating option as it produces little to no waste; Powder coating powder overspray can be collected and recycled, which is partly the reason behind its environmentally friendly cred. All these qualities make powder coating attractive, and there are many companies in Taiwan from which you can buy powder coating powder for industrial applications.
In this article we look at different types of powder coating powder and give you the information you need to buy the right one. We also look at where to buy powder coating powder and the brands and companies that sell them in Taiwan.
The cost is affected by the powder coating powder colour and finish
Most powder companies will produce a range of “standard” colours, with the option to choose another RAL colour that they can produce for you. These options will be represented in their powder coat colour chart or their sample cards. Powder coat colours can also be tailor-made for your specific needs, though not all companies provide this service. The colour options will start with the basic solid colour standard, and then get more exciting (and more expensive) from there.
Powder coating comes in a range of special effect finishes which are not available in liquid paint. These special powders include:
- Textures – These include sand (sandpaper appearance), hammer (like a hammered metal surface), wrinkle (commonly used on items like gym machines – rough yet smooth, with depth), and river vein (an almost wet look finish with a dimpled and crinkled effect). Textured finishes are usually more expensive because they require thicker films and special application methods.
- Gloss – A powder coating finish comes in levels of gloss from matte with no shine to full gloss, which is the shiniest. Between these are satin and semigloss.
- Metallics – A metallic sheen or sparkle effect caused by the inclusion of metallic pigments like aluminium flake or mica, ranging from shimmer to glitter. They come in bonded and unbonded (which describes how the metal is incorporated). Unbonded is the cheaper but less consistent finish. Metallics are generally more expensive due to the extra process involved in making them.
- Colour effects – These include translucent finishes, which add colour while also allowing the metal substrate to gleam through, and dormant powders – a bright candy finish, this is a two step effect with a typically metallic base coat and a clear top coat. These are particularly used on bikes.

Choose the right type when you buy powder coating powder
Powder coating is available in a range of resin types from the traditional epoxy and polyester to the more specific fluoropolymers and nylon. Next to the resin, it is also important to understand the curing process of the powder – when you buy powder coating, you should know whether you need a thermosetting or thermoplastic powder. In a thermoset resin, the molecules form crosslinks as they cure. This permanently alters the chemical composition of the coating. Thermoplastic powder coating resins have longer chain molecules to begin with and do not form crosslinks. Consequently, they can be re-melted if exposed to high enough temperatures.
Thermoset epoxy powder coating
A highly protective powder coating powder for interior applications
Epoxy resin is thermosetting, impact resistant, durable, corrosion resistant, chemical resistant, and highly adhesive as a powder coating powder. However it is not UV stable and therefore never used as a topcoat in exterior applications. It is mostly used in as a protective coating in interior applications and factory equipment. Fusion bonded epoxy powder coating is used to protect pipelines from corrosion.
Example: Axalta Nap-Gard FBE Powder Coating and Teknos EP 8024
Thermoset polyester powder
A low cost, but durable powder for exteriors
Polyester is the most common thermosetting resin type due to its flexibility, durability, mechanical resistance, chemical resistance, versatility and low cost. It is available as TGIC and TGIC-free formulations. Polyester powder coating is used for exterior applications. There are also Super Durable Polyesters which offer extended colour and gloss lifespans.
Example: Prismatic Powder Color Range and Sherwin Williams Powdura TGIC Polyester
Thermoset hybrid epoxy polyester powder
A thermosetting hybrid powder coating powder that combines the best properties of epoxy and polyester
The advantages of epoxy polyester powder coating include toughness, colour stability, chemical resistance and highly decorative finish. It has better weatherability than pure epoxy, but decreased chemical and corrosion resistance. Epoxy polyester powder coating powders are commonly used for office furniture, consumer products, shopfitting and interior applications.
Example: AkzoNobel Interpon 700
Thermoset polyurethane powder
The most expensive and highly durable powder
Polyurethane powder is made of a thermosetting resin and it has excellent corrosion resistance, UV stability and durability. However, it is the most expensive powder coating resin in the market. Polyurethane powder is used for exterior applications with a need for hardness and a lower film build, furniture, garage doors, lighting, etc.
Example: AkzoNobel Interpon 200 RTS and PPG Envirocron Polyurethane
Thermoset silicone powder
The heat resistant powder coating powder
Silicone powder forms a heat resistant powder coat up to 540°C. Therefore, it is used for high heat applications such as engines and exhaust systems, ovens, stoves, lightning and many others that need heat resistance.
Example: AkzoNobel Interpon HT 450 RTS
Thermoplastic nylon powder
A thermoplastic powder that provides looks and soft touch
Nylon powder coating is ideal for applications that require reduced friction, corrosion and chemical resistance, and a cosmetic, pleasant to touch finish. Therefore, this powder coating powder is used for kids’ playground equipment, shopping carts and wire shelving as well as applications in the healthcare industry.
Example: AkzoNobel Interpon TP RTS
Thermoset acrylic powder
Smooth surfaces for automotive industry with thermoset acrylic powder
Acrylic powder coating is results in a chemical resistant finish which is mainly used in the automotive industry. It helps create smooth, chip resistant clear coats on a variety of surfaces.
Example: PPG Enviracryl
Thermoset fluoropolymer powder
A thermosetting non-stick powder coating powder
The thrmoset fluoropolymer powder coating powder is known for its excellent weatherability, UV stability, and colour and gloss retention. It is typicall used in exterior industrial and architectural applications (like PVDF coating) as it is the longest-lasting, best-performing outdoor powder coating option.
Example: PPG Duranar and Axalta Alesta AR500
