WEATHER-RESISTANT POWDER COATINGS IN HOUSTON

Powder coating provides great protection and durability for many items subject to the elements. To get the best out of weather-resistant powder coatings in Houston, there are certain steps that should be taken to provide optimal protection, especially if refinishing an item that already has a powder coating. 

The first step is to prepare the surface to accept the powder coat. This can be done by media blasting. Media blasting in Houston is the process of using small granules (can be sand, crushed walnut shells, etc.) blown at high speed against an object to remove debris like old paint or rust. This step, where necessary, is vital to the life of the powder coat.

The next step is the actual powder coating application. A primer or rust deterrent can be applied to the surface before the actual powder coat to serve as a foundation. Zinc-rich primers can be used to prevent the formation of rust in humid or wet environments. The powders used in powder coating stick to the surface of the primed metal through electrostatic charge. 

The RAL color matching system, originally developed in Germany in the 1920s, represents a group of standards that allow for consistent reproduction of colors for a variety of applications, including powder coating in Houston. The name “RAL” comes from the German government organization that developed it—the Reichs-Ausschuß für Lieferbedingungen und Gütesicherung—but thankfully we have the acronym RAL, which is a lot easier on the tongue. It’s not necessary to be intimately familiar with the history and technical aspects of RAL colors, but a little knowledge about the system can go a long way in helping you determine the kind of powder coat colors and other coating options that are right for the job you need, whether it’s as simple as outdoor furniture refinishing or as complex as large-scale industrial coating.

RAL is a continuously evolving standard, with over 2,300 colors represented, as well as 213 “classic” colors. This wide range of available colors allows for accurate color matching across the spectrum. Color standards are important in accurate reproduction of colors; prior to the introduction of this standard, color matching was achieved by exchanging samples of colors between customers and manufacturers. If you’ve ever brought a paint sample to a hardware store, you know that this method can be unreliable in achieving the exact same tint due to the difficulty of mixing by eye and general inconsistencies in mixing. Color standards are much more accurate, allowing for exact formulation and reproduction of powder coat colors in any application from patio furniture refinishing to road signage (a common use case for RAL—the traffic signs you see on your way home from work are painted by RAL standard).

Although RAL-standard coating can be purchased by any company offering powder coating in Houston services, larger companies will likely be able to offer better deals and better access to specialty formulations due to closer relationships with manufacturers and larger-volume orders. Whether you need a simple outdoor furniture refinishing job or large-scale coating services for construction or industry, consider working with an experienced and capable powder coating company that has the skills, knowledge, and access of RAL powder coat colors to get your job done right.

In the pursuit of bringing hydrocarbons to market, there are many obstacles, both natural and man-made. Some of these difficulties can be circumvented, but others, like corrosion, are unavoidable. As much as oil and gas production companies would love to dodge this process altogether, it’s a natural part of chemistry and physics, and it’s not going anywhere any time soon. Over the decades, many technologies have been created to resist or prevent corrosion-damage to pipelines. These pipelines are essential to the delivery of hydrocarbons, but are susceptible to corrosion damage from the heat, moisture, and abrasives that are often present in these working conditions. One such technology used in the battle against corrosion is fusion bonded epoxy coatings (FBE).

FBE coatings are supplied by multiple manufacturers. Axalta is a leading provider of protective coatings throughout North America, offering an array of high-tech FBE options. Axalta Nap-Gard® 7-2500 Fusion Bonded Epoxy is one such coating, designed to provide corrosion protection in the demanding oil and gas production environment. In addition, Nap-Gard® 7-2500 is used in transporting wastewater and saltwater, each of which present their own challenges that must be addressed.

Nap-Gard® 7-2500 is designed to provide protection for both internal and external surfaces of pipeline. The protection of both surfaces is important: internal surfaces are exposed to chemically-active hydrocarbons, while outside surfaces can be exposed to high heat, high pressures, and abrasives such as salt. The 7-2500 specification is formulated to withstand high temperatures of 107°C (225°F)—vital heat protection in the unforgiving oil and gas production environment. In addition to providing this protection for oil and gas applications, the product complies with NSF-61 specification, meaning that it’s approved for transporting potable water.

Powder coating in Houston isn’t just important for the protection of pipelines in the oil and gas industry—it has applications in many other industries. In the economic powerhouse of Houston, powder coating is also used in residential and commercial construction. From the fencing and awnings that protect our homes to the railings, banisters, gates, and light poles that provide accessibility to commercial spaces, powder coating protects a variety of surfaces in Houston’s hot and humid climate.

The advanced electrostatic application process used in powder coating provides an especially resilient and durable surface, but it’s also aesthetically pleasing. Powder coat colors are readily available in a wide variety of on-hand stock, and if stock colors don’t provide an exact match, coat colors can also be specially formulated to match a specific need.

The powder coating in Houston process adheres to strict preparation and quality standards no matter the surface or application. Architectural finishes, like those that would commonly be used in residential or commercial spaces, must follow the American Architectural Manufacturers Association (AAMA) standards. The AAMA provides offers three specifications for the performance that a coating is expected to achieve:
