Understand what you need when you pick powder coating powder
Powder coating may be forever associated with hotting up vehicles, but it is far more than that. 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 cost effective – it produces little to no waste as powder overspray can be collected and recycled. This also makes it an environment-friendly coating option. All these qualities make powder coating attractive, and there are many companies across Canada where you can buy powder coating powder.
In this article we look at powder coating powders 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 across Canada.
How powder coat colours and special finishes affect powder price
Colour options will start with the basic solid colour standard, and then get more exciting (and more expensive) from there. Most powder companies have 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.
Powder coating comes in a range of special effect finishes which may require extra clear coats or special application techniques. These special powders include:
- Gloss – A powder coating finish comes in levels of gloss from flat/matte, with no shine, to full gloss, which is the shiniest. Between these are satin and medium gloss.
- Colour effects – These include translucents (which add colour while also allowing the metal substrate to gleam through), and dormants (a two step effect with a typically metallic base coat and a clear top coat to get a bright candy finish). These are particularly used on bikes.
- 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.
- Textures – These include sand (sandpaper appearance), hammer (like a hammered metal surface), wrinkle (commonly seen on items like gym machines – rough yet smooth, with depth), and river vein (an almost wet look finish with a dimpled and crinkled effect).
$15 per pound is the average powder coating powder price, but of course this changes with brand and specializations. As an example, Cardinal Paint sells its Cardinal White powder coating powder in 5lb boxes retailing at $60 per box. 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 specialized the powder, the higher the price. Powders are commonly sold by the pound, with the cost-per-pound decreasing as the volume increases.

Choosing the right powder coating resin for your application
Like liquid paint, powder coating powder is available in a range of resin types from acrylic to polyurethane. These resins can be divided into two broad categories based on how they cure: thermoset and thermoplastic. In a thermoset resin, the molecules form crosslinks as they cure. This permanently alters the chemical composition of the coating. Thermoplastic 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.
|Powder Coating Powder Type||Description||Uses||Product example|
|ACRYLIC POWDER||A thermosetting resin with good chemical resistance.||Mainly used in the automotive industry for smooth, chip resistant clear coats.||PPG Enviracryl|
|EPOXY POWDER||A thermosetting, impact resistant, durable, corrosion resistant, chemical resistant, and highly adhesive powder. Not UV stable.||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.||Axalta Nap-Gard FBE Powder Coating|
|POLYESTER POWDER||The most common thermosetting resin type due to its flexibility, durability, mechanical resistance, chemical resistance, versatility and low cost. TGIC and TGIC-free formulations.||Used for exterior applications. There are also Super Durable Polyesters which offer extended colour and gloss lifespans.||Sherwin Williams Powdura TGIC Polyester|
|HYBRID EPOXY-POLYESTER POWDER||Toughness, chemical resistant, colour stable and highly decorative. It has better weatherability than pure epoxy, but decreased chemical and corrosion resistance.||Commonly used for office furniture, consumer products, retail/shopfitting and interior applications.||Cardinal Paint Epoxy Polyester Hybrid H-Series|
|FLUOROPOLYMER POWDER||Thermoset fluoropolymer powder coating isas they have excellent weatherability, UV stability, and colour and gloss retention.||Typically used in exterior industrial and architectural applications (like PVDF coating) as they are the longest-lasting, best-performing outdoor powder coating option.||PPG Duranar|
|NYLON POWDER||Thermoplastic powder used where friction reduction, resistance to corrosion and chemicals, and a cosmetic finish are required.||Kids playground equipment, shopping carts and wire shelving use nylon coating, as well as applications in the healthcare industry.||AkzoNobel Interpon TP RTS|
|POLYURETHANE POWDER||A thermosetting powder with excellent corrosion resistance, UV stability, and durability, but more expensive than alternatives.||Used for exterior applications with a need for hardness and a lower film build, furniture, garage doors, lighting, etc.||Spectrum Powder Manufacturing PU Range|
|SILICONE POWDER||A heat resistant powder coating for temperatures up to 1000°F.||For high heat applications such as engines and exhaust systems, stoves, ovens, lighting and others.||AkzoNobel Interpon HT 450 RTS|
Where to buy powder coating powder in Canada
If you are looking to buy powder coating powder for your business or a large project, there are several big companies operating in Canada who provide powders for your needs. These companies include PPG, Sherwin Williams, and Axalta, just to name a few. Below is a table outlining a few of the products available on the Canadian market.
For the at-home hobbyist with wheels or garden furniture to coat, there are many online portals that sell powder in smaller quantities. The bigger companies like PPG are unlikely to provide a single pound of powder for a small application, and a pound will get you very far. Companies like The Powder Depot, Prismatic Powders, KCI International Powdercoating, and Rosey’s Powder Coating sell a range of powder colours, effects, and chemistries by the pound for these types of applications.
