How Can Powder Coating Be Improved?

written by Angie Johnson, Product Development Engineer

What is Powder Coating?

Powder coating is a finishing process that utilizes free-flowing, dry powder to create a durable surface on products. The powder is applied electrostatically by grounding the part to be coated and adding a positive charge to the powder particles through a spray gun.

The coated part is then cured in an oven which allows the powder to melt and flow into a strong and attractive coating. It is primarily used on metal surfaces but can be used for other surfaces such as plastic and medium density fiberboard for specific applications.

Powder coating is used in a wide-range of industries and applications. Frequent uses include household and commercial appliances, furniture, bicycles, industrial equipment, automotive and tractor parts, toys, restaurant equipment, kitchen and bath fixtures, door hardware, shelving, rebar for bridges, and many others. Powder coating has the durability and attractive finish to be used almost anywhere. An almost infinite number of colors, specialty finishes and textures are available.

Benefits of Powder Coating

Powder coating provides several benefits over conventional liquid paints, including increased durability, thicker coatings with no running or sagging, and consistency between vertical and horizontal surfaces. Unlike traditional paints, powder coating does not require a solvent component and emits little to no volatile organic compounds (VOCs) making it environmentally friendly. Overspray powder can also be recycled. Powder coating provides an attractive finish with durability to impact, moisture, chemicals, heat, and UV exposure.

Can it be Improved?

Powder coating has been available for more than 60 years and has developed into one of the most durable and environmentally friendly coatings available. Can it be improved? At Microban, we say yes!

The addition of powerful Microban technology can enhance powder coatings by prevent the growth of harmful bacteria that can cause stains and odors on the coated surface. The possibilities for powder coating with Microban are almost endless.

Imagine the powder coating on refrigeration and freezer units, display cases, shelving, carts, counters, and doors in grocery stores that protect surfaces from bacterial growth and keeps them cleaner in between cleanings.  

Other excellent antimicrobial powder coating applications  include door knobs, kitchen and bath faucets, gym /fitness equipment, and furniture designed for use in residential, educational, and commercial environments.

In partnership with Spectrum Brands, makers of Kwikset door hardware, the Microban team set out to create a process that would both meet the rigorous durability requirements of door hardware, and provide an added level of protection for these high touch surfaces. Ultimately, Microban technology was incorporated into the powder coat materials used for Kwikset brand door hardware.

Antimicrobial powder coatings with Microban technology have been tested using stringent standardized test methods, as well as simulated real life exposure challenges. Built-in Microban technology works continuously within the structure of the coating while maintaining the aesthetics of the product surface underneath. Microban technology is added to products at the point of manufacture, so it will not wash off or wear away and continue providing protection for the life of the product.
