A complete powder coating powder guide Singapore
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 several companies in Singapore 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 Singapore.
How powder coating colours and effects influence the price
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:
- 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.
- 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).
- 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.
$8 per kilogram is the average powder coating powder price, but of course this changes with brand and specialisations. As an example, AkzoNobel’s Interpon 100 epoxy powder in basic white retails at $848.08 per 25kg box, breaking down to $33.90 per kilogram. When you look to buy powder coating powder you quickly realize the more extreme the effect or outrageous the colour or texture, the more expensive it is.
Metallics in general are more expensive due to the extra processes involved in making them, the special textures require extra thick film build or specialty application techniques which also increase the price. The more specialiced the powder, the higher the price. Powders are commonly sold by the kilogram or pound, with the cost-per-kilo decreasing as the volume increases.
8 different types of powder coating powder for different uses
Like liquid paint, powder coating powder is available in a range of resin types from acrylic to polyurethane. Another important factor to understand is the curing process of the powder. In this respect powders can be divided into two broad categories: thermoset and 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.
They are both applied through the usual powder coating methods, but thermoplastic powders are more flexible, where thermoset powders are heat stable. Most powder coating powders are thermoset powders. Below is a list of the main resin types and their applications. It is important to choose coating products based on the substrate, environment, and use that it is required for.
- NYLON – Thermoplastic powder used which require friction reduction, resistance to corrosion and chemicals, and a cosmetic finish
Uses: Kids playground equipment, shopping carts and wire shelving use nylon coating, and applications in the healthcare industry
Product example: AkzoNobel Interpon TP RTS
- ACRYLIC – A thermosetting resin with good chemical resistance
Uses: Mainly used in the automotive industry for smooth, chip resistant clear coats
Product example: PPG Enviracryl
- EPOXY – Thermosetting, impact resistant, durable, corrosion and chemical resistant, and highly adhesive powder. Not UV stable
Uses: Mostly as a protective coating in interior applications and factory equipment. Fusion bonded epoxy powder coating is used to protect pipelines
Product example: –Axalta Nap-Gard FBE Powder Coating
- POLYESTER – The most common thermosetting resin type due to its flexibility, durability, mechanical resistance, chemical resistance, versatility and low cost
Uses: Used for exterior applications. There are also Super Durable Polyesters which offer extended color and gloss lifespans
Product example: Prismatic Powder Color Range and Sherwin Williams Powdura TGIC Polyester
- EPOXY POLYESTER HYBRID – Toughness, chemical resistant, color stable and highly decorative.
Uses: Commonly used for office furniture, consumer products, retail/shopfitting and interior applications
Product example: AkzoNobel Interpon 700
- FLUOROPOLYMER – Thermoset fluoropolymer powder coating isas they have excellent weatherability, UV stability, and color and gloss retention
Uses: Typically used in exterior industrial and architectural applications (like PVDF coating) as they are the longest-lasting, best-performing outdoor powder coating option
Product example: PPG Duranar and Axalta Alesta AR500
- POLYURETHANE – A thermosetting powder with excellent corrosion resistance, UV stability, and durability, but more expensive than alternatives
Uses: Used for exterior applications with a need for hardness and a lower film build, furniture, garage doors, lighting, etc
Product example: AkzoNobel Interpon 200 RTS and PPG Envirocron Polyurethane
- SILICONE – A heat resistant powder coating for temperatures up to 540°C
Uses: For high heat applications such as engines and exhaust systems, stoves, ovens, lighting and others
Product example: AkzoNobel Interpon HT 450 RTS
