In NCCA Tool Kit # 26, “Factors Influencing the Long-Term Performance of Prepainted Metal Building,” an emphasis was justifiably placed on the selection of materials. That selection process starts with a substrate that must provide the corrosion-resistant properties for the environment in which the prepainted product will be used, probably for decades. Whether the specifier is considering steel or aluminum, the mechanical properties of the material are of paramount importance. After all, all prepainted metal is post-formed, so the substrate, as well as the paint system, must be able to withstand the rigors of the fabrication process. With a steel substrate, it’s the thickness of the metallic coating layer; with hot-dipped galvanized steel, it’s the zinc; and with Galvalume®, it’s the Zn-Al metallic blend that needs to have an adequate thickness to provide the necessary lifetime and level sacrificial of galvanic properties. There are many parameters to consider. Continue reading
It seems so simple: We cut a finger or bruise a knee, and a week or so later we’re all better. You snip a small branch of basil leaves to make pesto, and before you know it there is another branch of basil leaves sprouting from the cut. If plants and animals can heal and thrive, why not other organic material, like polymers used to make coatings?
These days, it’s not uncommon to hear businesses from nearly every industry discuss “sustainability” or plans for a more sustainable future. As the term becomes more ubiquitous in today’s business planning, its definition can be somewhat vague. For our purposes, sustainability refers to a company’s efforts in reducing its environmental impact through the use of more environmentally-friendly building materials and less consumption of natural resources. While the coating industry works diligently in manufacturing products that adhere to high standards for sustainability, there are several ways to be more sustainable and environmentally conscious.
1. Reduce the use of volatile organic compounds.
For a long time, volatile organic compounds, or VOCs, played a large role in the coating industry because they contain properties that assist in applying coatings to a surface. Continue reading
Year after year, the coated metal industry continues to innovate and inspire designers and architects with new aesthetical and color options that have reshaped consumer expectations. More than ever, buildings have the ability to stand out, while reaping the durability and environmental benefits of using prepainted metal. Here are just a few of the latest trends in coated metal that define why there’s never been a more exciting time in the industry.
1. Textured Products
Textured, painted metal products were introduced in the 1980s to expand the visual, durability and eco-friendly possibilities of incorporating these products into commercial and residential applications. Continue reading
We’ve seen the beauty and innovation prepainted metal has brought to countless exterior applications. But did you know prepainted metal can be an integral part of a number of interior applications? Here are five ways prepainted metals can spice up the interior of any building:
1. Interior Walls
Prepainted interior wall panels are available in a variety of profiles, including ribbed, insulated (foamed), composite and architectural shallow flat styles. These panels are lightweight and can be installed more quickly than traditional walls. They can also take on dramatic shapes with colors or laminates that create striking design elements.
2. Ceilings Continue reading
When it comes to coatings, the resin, or “binder,” acts as an adhesive that keeps all the elements of a paint formulation together. The resin selected is the backbone of the coating and therefore the primary source for determining the coating’s durability and physical properties. When choosing a resin-based coating, it’s important to know some of their key features.
Fluoropolymer resins are known for non-stick properties and their ability to avoid UV damage. The most well-known best performing resin in this category is Polyvinylidene Fluoride (PVDF). PVDF is at least 70 percent of the binder used in superior performance coatings, while an acrylic resin makes up the other 30 percent. PVDFs are found in coil coatings, where exceptional durability is desired. When compared to other coatings, PVDF resin-based coatings were the only coatings that did not lose their original gloss within 2-5 years.
One of the most common causes of failure for resin-based coatings is the risk of color fading. Continue reading
For most buildings, the exterior is designed to be its most important eye-catching feature. While we’re wired to be extra mindful of the cleanliness and maintenance of the interior of our homes and offices, we sometimes neglect to remember to give the outside of our buildings the proper care. One of the biggest advantages of prepainted metal is its easy maintenance, but there are a few easy steps to make your metal panels shine bright.
Rinse the surface with water.
This sounds like a no-brainer, but this is one of the easiest ways to clean coated metal panels. Dirt and debris built up over time can affect the quality of the panel’s appearance and potentially reduce the lifetime of the coating. Simply rinsing the surface with a garden hose or pressure spray system will clean most buildups on a coating surface, allowing the panels to look brand new.
Clean with soap or water for difficult areas.
