Powder coating aluminum is a process that produces versatile, sustainable finishes. Powder-coated aluminum is useful for industries as diverse as aerospace and architecture, along with many others. This step-by-step guide will explain the process of powder coating aluminum.
Manufacturers and product fabricators send their aluminum products for powder coating as a finish for several reasons. The main benefits of this finish include:
Before beginning, manufacturers will determine their specifications for the end product. The actual process of powder coating aluminum involves up to 11 different steps:
Before preparing aluminum for powder coating, it is essential to ensure the material is free of inorganic contaminants like grease, rust or debris. If the material is being repurposed, any previous finish also needs to be removed. This is achieved through abrasive blasting to prepare the surface.
This step contributes to better powder coat adhesion and enhanced finish durability.
Once the aluminum is clean, it is ready for pretreatment. Methods vary, but Keystone Koating&#;s thorough aluminum pretreatment process has eight stages:
Using a thorough pretreatment process during aluminum powder coating can sometimes eliminate the need for additional abrasive blasting.
If the powder coating is for an aluminum component with holes, threads or machined areas that need to stay clean, masking blocks off those areas to protect them during powder coat application. Masking is also helpful for creating straight lines across a surface.
Special, high-temperature masking tape that can survive temperatures approaching 400 degrees Fahrenheit is necessary for this process.
This is an optional step but an impactful one, especially for products intended for outdoor use. Applying a quality non-zinc primer coat to the aluminum before the powder coating can prevent corrosion, even in severe weather and environments with high moisture and high airborne salinity. The most effective primers on the market can extend the life span of a powder coat four times over.
If longevity is important to you, it is wise to ask your coating partner to use a primer before applying the powder coat.
With the aluminum surface clean, pretreated, masked and primed, the next step is to apply the powder coat. The powder itself could be epoxy, polyester or fluoropolymer, depending on the component&#;s application. While other methods exist, electrostatic spraying is the most versatile and precise way to apply powder coating to aluminum components.
This method uses electrostatic spray guns to apply the powder coat. The guns charge the powder particles with electrostatic energy on their way out of the spray nozzles. The coating then forms a strong electrostatic bond with the aluminum surface. This process continues until the component is fully coated with powder for the desired finish and thickness. The electrostatic bonds are so strong that the coat can protect the aluminum for years or even decades.
Next, the freshly applied coat requires curing in an oven. Curing melts the resins in the powder to form a durable coat. Most aluminum powder coats will cure at 325-400 degrees Fahrenheit (163-204 degrees Celcius) for 10-25 minutes. Coating professionals calculate the exact time and temperature to cure a coat based on factors like:
Through careful optimization of curing time and temperature, coating professionals ensure an even, durable finish.
After leaving the curing oven, the component must cool down. This is when the powder solidifies to form a hardy protective layer over the aluminum surface. Proper cooling is crucial to prevent thermal stress, minimize the potential for defects and enable professionals to handle the component safely while inspecting and packaging it.
Leaving the component to cool naturally ensures gentle acclimation to the ambient temperature. However, in some cases, the material or conditions may demand more rapid cooling methods, including:
After cooling, the powder coat is complete. A reputable coating professional will conduct rigorous inspection and quality testing before returning a coated component to a client. Top-tier quality control combines an experienced eye with specialized testing equipment to check the coat&#;s adhesion, thickness, cure and appearance.
Keystone Koating conducts these checks in a quality assurance laboratory dedicated to thorough testing and top-quality standards. Our testing procedures follow the quality and reliability standards of the American Society for Testing and Materials (ASTM) and the American Architectural Manufacturers Association (AAMA). We also hold ISO - certification.
Quality testing ensures the coat meets the coating company&#;s standards and the client&#;s specifications.
Once the component passes quality control, it is ready for packaging and shipping. If your component requires assembly, most coating professionals will return the coated parts to you to assemble yourself. However, if you choose Keystone Koating, you can ask for minor assembly on-site as a value-added service.
The powder-coated aluminum component is placed in protective packaging for convenient shipping. If your component is destined for the retail or wholesale market, provide Keystone Koating with the packaging materials and specifications and request custom packaging as a value-added service. This ensures the presentation standards you want your customer to experience.
Explore the shipping options your coating partner offers to ensure a delivery that meets your timeline. Keystone Koating provides multiple fast shipping options to suit your needs and preferences. Arrange a direct shipping schedule that gets all your completed orders to your location on time.
