Tips to Getting Colour Right in the Powder Coating Industry

Powder coating is a dry finishing process that can improve efficiency, maximize production, and enhance environmental compliance. This coating is available in virtually limitless colour options, so it can be hard to know what colour to use. Read more about how to pick a powder coat colour.

What Is Powder Coating?

Powder coating is a dry powder made from curatives, flow modifiers, and leveling agents. This mixture is applied to the surface using electrostatic spray deposition (ESD) and a spray gun. The electrostatic charge helps attract the powder particles to the surface, creating a bond. Once the powder coating is applied, it is cured with heat.

This durable finish protects the surface from rust, corrosion, and exposure to the elements. It can also be used as a decorative finish to give the equipment a certain colour.

Tips to Get Colour Right in the Powder Coating Industry

Getting the right look for your equipment can be challenging since there are so many options available. If you’re looking at a powder coating colour chart and still cannot decide which colour to go with, follow these tips for picking a powder coat colour:

• Get in different lighting: Light influences how we perceive colour. View your powder coating sample in the sunlight, a shadowed space, and fluorescent light, and put the light source at different angles. These different viewing conditions will give you a good picture of what the powder coating will look like.
• Decide on a colour style: If you are powder coating just one part of your equipment, you can choose an accent colour to make it pop, a contrasting colour to stand out, or a complementary colour to fit the look.
• Hide the part’s imperfections: Dark and metallic powder coating colours best hide imperfections on the part’s surface.
• Choose a semi-gloss or satin finish: A semi-gloss or satin powder coating finish gives you the right amount of reflection to make the part look nice. A glossy finish can be too shiny in some conditions.
• Go for an industrial look: Matte and flat finishes are the best choices if you want a tough or commercial look for the piece.

Stay Consistent With Colour With Spectrophotometric Solutions

Spectrophotometric analysis of your powder coatings provide the best quality control by measuring the exact colour of the powder coating, allowing for colour matching. This analysis will help your company win bids for clients who want a specific colour of your powder-coated products. Once you achieve the desired colour, an accurate, feature -rich spectrophotometer will equip you to ensure consistency and repeatability.
