Often when I first approach metal fabrication workshops, I commonly find that not many are overly concerned with finishing processes. Like many in the trade, they are focused on welding precision, structural integrity, and timely delivery. Getting the fabricated parts deburred is already a step they do not relish but must endure. Then their customer also expects them to arrange the coating of the metal fabrications, another step that is not their core competency. However, in order to land the order, they must include, thus outsource, this extra step.
After all of this "extra" work, if there are rejects due to the coating, the metal fab shop is now behind the proverbial eight ball. Not only will they now be late with the delivery, but they also must look at getting the parts stripped of the coating and re-coated. Either that or replace the parts. Even worse, if the coating fails "in the field"; replacements, charge-backs...all kinds of issues can result. One very common cause of failed coating is rust.
Latem Industries Limited has become a one-stop shop. Not only are we one of the largest deburring job shops in North America, we also offer many coatings such as nylon and plastisol. We also have expanded into the winning combination of electrostatic coating followed by powder coatings. It isn't just a solution - it's a game changer.
Electrostatic coating sounds complicated at first. People imagine high-voltage sparks and lab coats. But in essence, it's beautifully simple. The process involves submerging metal parts into a bath containing paint emulsion and then applying a voltage. This creates a positive charge in the coating particles, and since metal parts are naturally conductive (and usually grounded), they attract the charged particles like a magnet. The result is a consistent even coat. E-coat in itself is a formidable coating used in the proper context. Latem Industries processes a multitude of parts in the automotive, furniture and other sectors with great results. Adding powder coating over top of the electrostatic coating is next level.
Powder coating, is essentially paint in powdered form that’s also applied electrostatically. Once the charged particles cling to the metal surface, the item is baked in an oven. The heat melts the powder, turning it into a smooth, durable, and seamless finish that’s resistant to scratching, chipping, and corrosion as well as excellent against UV, making it an ideal outdoor coating.
Why the Two Together Are Better Than One
Using electrostatic coating followed by powder coating might seem redundant, but the synergy between them is impressive. Here's why this layered approach has become a go-to for many industries.
- Superior Adhesion and Coverage
The initial electrostatic primer (either a liquid epoxy or a specially formulated base coat) provides excellent bonding to the metal. This ensures that the powder coat adheres even more securely during the curing process. The electrostatic application method also ensures hard-to-reach crevices and curves are evenly coated.
- Maximum Durability
Powder coating alone is tough, but when applied over an electrostatically applied primer, it becomes virtually impervious to the elements. UV rays, moisture, salt, and chemicals stand little chance. This has been especially useful for outdoor furniture, gates, and railings installed near the ocean—no more rust complaints.
- Cost-Efficiency Over Time
The reduction in rework, warranty claims, and touch-ups can be substantial.
- Eco-Friendliness
Powder coating contains no solvents and releases negligible volatile organic compounds (VOCs), unlike traditional wet paint. Combining that with the efficient transfer rate of electrostatic coating makes for a process that's cleaner for the environment.
- Aesthetics and Finish Quality
Clients notice the difference. Whether it's a vibrant red bench or a matte black stair railing, the finish looks professional, smooth, and high-end. And since powder coating comes in endless colors and textures—metallics, hammertones, glossy, matte—it opens up creative possibilities.
In summary, Latem Industries is a great option for your metal finishing needs. We offer many different deburring processes, along with different medias, and can handle your coating needs as well, offering nylon coating, plastisol coating, e-coating and/or powder coating.
